Hawk arrived well packed with no damage. Assembled with radio without adding any unnecessary weight. Only 3 light weight servos. Had to add a small amount of nose weight to get CG right. All up flying weight was just over 130 gm. Model was nicely finished when arrived. Flies nicely. Little bit tight for putting in radio in nose.
this is my first dlg. being use to larger gliders of course things all somewhat smaller but plenty of room for installing 3 servos. Once servo arrangement was decided it is easy to assemble. wings already have bolt holes and fixings in fuselage are in place in fuselage so that took a lot of the stress out of assembling compared to other models. decided on sd100 servos which fit fine. not flown yet as ever first class service from hyperflight.
As usual, the kit arrived well packed.
Delivery was delayed because it stopped at customs and with the new rules for purchases outside the EU, it is necessary to pay taxes.
The kit parts have a super-precise laser cut so it will be a delight to assemble this gem. Thank you.
Although I finally was very pleased with the results with Oralight covering after painting the stuff on I feared I’d ruined the wing and tail. It does seem too thick (next time if used I’d thin it) and areas were over generously painted whilst other sparsely. After drying for several days it was still sticky and like Brer Rabbit and the Tar Baby I couldn’t put fingers anywhere and had to prise them off. Too easy for stray wood shavings to get where they shouldn’t. That aside to my surprise the covering could be easily repositioned before tacking and shrinking and I’m extremely pleased with the final results. Basically it’s stressful and a devil to deal with but the end result was worth it.
Bought this alongside my Weasel Trek slope soarer and I can use it to charge both the 4-cell 750mAh NiMH battery for the glider and the 5-cell 1800mAh NiMH battery in my Futaba transmitter.
I always have a USB power supply of some sort with me, so with this charger the amount of charging clutter I need to take on holiday with me has been greatly reduced!
Bought this to decorate and personalise my Weasel Trek slope soarer and it did a great job. It’s very sticky and it had no problem sticking to the smooth shiny foam surface of the Weasel.
It doesn’t have much stretch to it though, so if your model has anything more than the slightest compound curve you’ll need to cut darts into the film to get it to follow the surface. Unfortunately, the colour of the film appears to be applied to its upper, non-sticky surface, and where the darts end I’ve found the colour will quickly wear / flake off. It’s no big deal though, and is obviously only visible up close.
Given you obviously can’t use heat-shrink film on a foamie (or you won’t have a flyable foamie afterwards!), this does a good job. Bear in mind you don’t get a lot in each pack (check those measurements), so make sure you order enough for your needs.
Having always loved slope soaring but rarely having the opportunity to fly, I wanted to buy a compact slope soarer that I could take on holidays and which could handle a range of wind conditions — and could also take the odd knock and bump without breaking. My previous ‘holiday’ slope soarer — the balsa and fibreglass Nano Floh — was great fun and was very lightweight, but the film covering over the balsa wing was prone to punctures and the wing itself was also pretty delicate.
The Weasel Trek has fitted the bill perfectly! It was a pleasure to assemble, and literally only required the use of a small screwdriver to complete the build. I then added some red and black adhesive film (sold by HyperFlight) and the decals that came in the box to personalise the plane and also make it more visible in the air.
I’ve now flown the Weasel at 4 different locations, each with different hill profiles and with varying amounts of wind (from light / medium to seriously stiff!), and the Weasel has handled all the conditions very admirably! I almost always fly it using the ‘high’ rates as detailed in the manual, and it gives it very spritely performance. Being basically a large wedge of lightweight foam, it doesn’t carry its speed particularly well (certainly compared to the all glass-fibre 2m slope soarer I used to fly), but it still recovers height well after a fast dive and generally a blast to hurl around the sky.
I’ve also developed my own lead ballast weights which allows me to add 15g, 30g or 45g of lead to the ballast cavity in the underside of the wing just behind the finger rest. I’ve not noticed a huge difference in performance yet, but the lead will certainly help the plane carry its speed better and also penetrate into stronger winds. The weights were formed by pouring molten lead into square aluminium tubing, cutting it to length, covering it in clear heat-shrink, and then drilling a 3mm hole in the middle for an M3 nylon screw. I then sunk an M3 threaded pillar into the foam at the bottom of the ballast cavity for the screw to screw into. Fortunately the foam wing is deep enough to allow either both 15g and 30g weights to be used together, or for no weights to be used, without the M3 nylon screw sticking out of the top surface of the wing, even when fully screwed in.
The Weasel Trek is a blast to fly and I’m so glad I bought it — I now take it everywhere with me on holidays if there’s a chance we will encounter the slightest of hills!
Nicely built and rock solid construction. Much more robust than the Sunbird. Build is quite easy. Flies great. While the Stabilizer is technically removable, its pretty hard to do in the field, so its essentially not. Impressive , cordial and speedy response in ordering!
The controller is brilliant the instruction could be so much better. 1st for windows 10 needed to install the drivers from her https://ftdichip.com/drivers/ then could be programmed with the card although in all honestly the default settings from hyperflight would be fine for glider. The multiplex telemetry is fantastic and you can use this and a various. Would buy same again just for the telemetry
Purchased this plane with Powerline Turbo 1010, YGE-35LVT and having just flown it off a slope can't tell you how impressed I am with both ballast and without. The flaps and control and landing is incredible, the rudder control is awesome. It is incredibly sensitive to camber / reflex changes. All in all very very pleased. With the motor it goes vertical with a 850mah and the telemetry from the esc is just what i wanted. Will be interested how it thermals but off a slope it worked wonders.
nicely presented kit with excellent plan. took 8 days to build and fit motor to F5 spec with Hacker A7 geared motor- plan shows conversion and 2 motor bulkheads are included with different hole spacings. went together very well though tailplane pylon is fiddly. wing tips are very weak and I braced them with bent wire at T.E. and carbon rod into mainspar. turned up some stainless ballast bars to give an extra 100g and have now flown with and without ballast- very impressive all-round. looking forward to some competitions.
This is already the third glider bag I buy.
Excellent quality, strong and good layout internally.
They last a lifetime.
But there is a small minus.
Since the fuselages are getting thinner, they can no longer really be fixed.
When you carry the glider bag, the fuselage rotates due to the weight of the rudder.
Actually, the rudder should also be able to fixate so that it remains flat.
This reduces the chance of damage.
But otherwise more than satisfied.
After writing my previous review I noticed that the product image shows only three gears and two shafts. All sets I have received so far actually contain five gears, three shafts, and an output shaft ball race. This is the entire gear train except for the motor output gear which is not replaceable in any case.
I have used quite a few of these as detailed in my review of DS125MG servos. In all cases there were no installation issues and the servos now function as well as new.
The gear set is comprehesive and even includes new shafts. In my experience so far the only gears to suffer damage are the two in final drive, and although it is probably good practice to replace the entire set I have not done so yet with no ill effects. However I have used some of the spare gears to minimise the backlash on a couple of used but servicable servos by selective assembly.
I am entirely satisfied with these items and would recommend anyone using the 10mm KST servos (the gearsets fit most of them) keep a few in stock.
Neil's service is always exemplary and his prompt and reasonably priced postage rates make Hyperflight my preferred supplier.
Before going further I should state that I am delighted with these servos and Neil's service. The servos have minimal backlash, good speed and centering, and under normal conditions are extremely reliable. However, like any mechanism they have limits.
I fly mostly on slope and the normal heavy usage that this entails coupled with my inexperience with heavy, slippery planes has given these servos an extreme trial and revealed the conditions under which they could fail.
When I bought my first moulded glider, a second hand but immaculate Valenta Prosecco full carbon it was fitted with these servos on the ailerons, and I also installed on the flaps before I flew the model.
First flight I had a hard dorked landing in turbulence and damaged the fuselage but no apparent damage to servos.
On rebuild I installed a motor to get some landing practice away from slope and had many successful flights but with the inevitable failures to fully raise flaps on landing.
One day I noticed that the flaps servos although operating correctly had some notchy movement at certain points in their travel. I decided to investigate and discovered that both of the servos had missing teeth on their output gears. Purchased replacement gears from Neil and servos functioned perfectly after they were fitted (see my review of replacement gearsets).
Later a combination of gusty weather and over confidence led to a vertical arrival at high speed. Luckily the ground was soft but still the carbon wing joiner was cleanly sheared off both sides. Miraculously the only other damage apparent was a couple of very minor cracks in one wing and the tail broken off - a tribute to the massive construction of the Prosecco. However further inspection revealed that the plastic flap servo arms had shattered and the servos had rough spots in travel, aileron servos seemed OK initially but careful inspection also showed rough spots. All of the servos had broken teeth. Since rebuild of plane and servos I have had many more flights with absolutely no issues.
Given the hard usage detailed above it is no surprise that the gear failures occurred. The output gears are robustly dimensioned and are used on a wide range of KST servos up to 10kg.cm torque. However they are made from case hardened steel and large impact loadings cause brittle failure of teeth. To some extent this is a good thing as it protects the other parts of the mechanism from damage, after rebuild all the servos have shown no ill effects over a long period.
Usually the failure is of a single tooth and can be quite difficult to detect. It is very good practice to carefully inspect the servo operation after any hard landing or flap contact, and dismantle and check the gears if there is any suspicion of damage.
Again I must state that I am completely satisfied with these servos and have no hesitation in recommending them.
Excellent service from Hyperflight. Quick and easy order from website. Quick delivery also.
Communication very good. Have used Hyperflight a few times now and recommend them as a top class supplier. H47 servos were just the job, if not the same as my SD100 servos in my Elf DLG.
Used these many times, they are great. Although ordered as Ripmax the H47 appear identical to SD100. They are a really neat unit but you need to find the right jewellers screwdriver for the servo arm locking screw. Definitely my favourite small lightweight surprisingly powerful servo.
Very good smooth operating fit with PTFE tube. Needs patience to obtain a secure straight long run inside a carbon boom, eventually I bound the tube to quarter by eight spruce spar (there may be better ways of doing this) which was fixed at servo and tail end of boom. I guess it’s much easier to install in a built up fuselage.
* there was some sticky residue from tape packing on the wire, this was causing resistance but sorted with a cloth and meths.
Ordered together with a Dart Mini2 as they were recommended for that model. The reviews below are split between "Great" or 'Horrible" and unfortunately the 4 I got belonged to the latter category... :(
They don't center well and most of all, they only move in random increments. Move the sticks slowly and they jump from one position to another by step. As they are transparent, I can see it's not an issue of play in the gear, but the motor just starting when it feels like it. Same issue with a different receiver and 5V supply. It made the otherwise great DM2 a bit weird to fly, with constant correction needed, especially on elevator. Not nice. I've since swapped them for Dymond D47/Robbe FS31 Pico and the difference is amazing! Unless you feel lucky and get a good batch, I'd avoid them and go for something else...
Looking at trying my hands at DLG, I was on the hunt for a 1m reasonably priced model, as I was not ready to invest hundreds of £s on something I might not like in the end. Read good reviews about the MD2 and found no better price then on Hyperflight (though I live in CZ). The glider was shipped pretty much the day of the order and arrived very quickly, very well packed with the BMS101 I had ordered too (note : avoid those). I was amazed by the quality and finish of the kit! Great set of accessories too, straightforward assembly, and it flies great!! Just be careful to land straight as the rudder is very thin and light and can bend break, but that's easily fixed with epoxy. Very happy with my purchase and HF service.
We now have three examples of the Kiwi flying in our club. They have proven to build well and fly well. The build requires care to deal with the thin balsa sheet that forms the wing leading edge, but the wing performs! Lots of lift, little drag. We have not seen any evidence of flutter under any launch or flight condition. The fuselage also requires care to build straight, but everything fits and it is strong and rigid.
Bought these to replace some homemade wingbags made for a 2nd hand Vibe2 I bought from Europe. Wasn’t completely confident they would fit. But, true to form, Neil has nailed it. Like a glove. Quality is very high - very like Vladimir in feel but actually better with high end stitching and embroid. The peg pocket is genius. One thing though. I’m a lefty and so the bags have to go on back to front. Can you switch a few for left handed flyers like me Neil ? Otherwise perfect. Delivery within 24 hours of the order. Thank you Neil and team.
I'm returning to the hobby after my youth, radio gear is so sophisticated, robust & cheap! When I started I could only afford a 3-Channel radio set. Also, modern kits like this are a revelation after cutting out ribs by hand, and CA has made the build process so quick. I used to have to hold wings down on a flat board overnight while the PVA cured. Anyway, on Neil's recommendation I got my eye back in with a Big Vick then built this X-RES Electro. I made a few mistakes but was able to recover them, that's the downside of the speed of CA!
I learnt to cover with Oralight, a bit easier than tissue & dope.
AUW was 483g + 10g to balance. Not bad for a beginner.
Neil's service and advice goes without saying and is repeated in the many reviews here.
I started off with the CoG at 77mm which was a mistake and I struggled to get stable flight. Two heavy crashes and subsequent repairs later, I put 10g of lead in the nose to move the CoG to 73mm and it was transformed. I am now rapidly learning how to fly again and have installed a Vario to monitor my height.
A few points:
The plans provided were not for the Elektro so caused some head scratching. I got some great advice on the RC Groups forums, one guy in Greece even sent me a soft copy of the correct plans that I think he'd got from the designer.
I think the nose has been shortened too much from the pure glider to suit the latest lightweight motors and LiPo cells, I installed the servos right up under the leading edge and have a 2S LiPo pushed right up to the motor but still needed some lead. I would have preferred a longer nose and more flexibility with gear location to achieve the CoG. The guy in Greece who sent me the correct plans has built 3 of these as electrified glider versions, I might do this next.
The airframe is amazingly strong given its built up construction and spruce main spars. I crashed it heavily enough to break the nylon wing bolt but that only fractured the false leading edge and I was able to splice in a new section. There's a bit of filler and it's not as pretty as it was, but it flies!
For info I've installed the following:
Servos: 4 x Bluebird BMS-101DMG.
Motor: ADH300L / MM1914-1100 Front Mount 39g 1100 RPM/V
Prop: GM 9x5 + 30mm Spinner.
Battery: Overlander 850mAh, 7.4v, 2S, 35C Supersport Pro LiPo (Perfect fit in the fuselage).
ESC: Overlander XP2 20A Brushless Speed Controller.
FrSky RC Gear with RX6R Receiver.
New version & logo. Yge is the best ESC and reliable for use on my F5J. Good co-work with my Jeti transmitter DS24. Hyperflight is reliable dealer for glider accessories. This is my 2nd time buying item from hyperflight. Very good quality and delivery especially ship to China.
These are excellent precise servos with really good centering. I am using them to drive the ailerons in my 3.8m F5J Explorer Q. The ailerons are really big, but it seems to work very well using the smallest size servo arm 3.5mm (!) with the Servorahmen IDS. Gives plenty of travel, even with such a small servo arm.
4 Stars only because they do not work down at 1S lipo voltages, in fact not below about 4.5V. I am using them with BEC voltage of 5.3 to 5.5 V with no problem.
I am using this prop with a 3S battery and the XPower F2919/10 Light motor in my 3.8m F5J Explorer. It works well and provides plenty of thrust for normal flying. The blades fold pretty flat against the fuselage. I have reduced the throttle limit to 80% because it was drawing 45A (static) at full power - though my power meter may not be accurate.
