The plane launches higher than other F3L planes I have. Workman ship was great. On the pre build plane I purchased. The spoiler position allows for great landing and control. I have ordered another purito. I would recommend the purchase of the Purito F3L sailplane,, it’s great to fly!
I am very happy with the quality of the wing and the fit and build of this plane. It went together really quick and flying is effortless. This plane signals lift just as well as my Vortex 4 and it thermals beautifully. It has no bad light characteristics and mine came out to 303 grams and it feels very light and floaty in the air. I get plenty of thrust with the 1507 motor paired with the 6x4 prop, also using the 2s550 to get a perfect balance with no added weight to get the CG right.
I really enjoy flying this plane and I love how well I can get it to slow down at landings for a very predictable and stable approach and landing.
Can't wait to get this into competition next month!
The only complaint I have is the lack of instructions. Where I missed this was in the wing joiner/locking. I ditched the supplied plastic locking gadgets for heavy duty paper clips. The plane handles well. I am still trying to figure out how to best program and control all the surfaces. I also have a Intro F5J wing I want to build to swap out in the field depending on conditions.
I enjoyed building this model. Easy to follow video. However, I ran exterior servo rods and fiberglassed the fuselage. I ended up with adding a little tail weight but it's a solid controllable model. I did have to work out a warp in the wing due to improper covering. But it's a blast to fly and looks nice.
As I write, I am part-way through the build. The plain box arrived very promptly from HyperFlight, and contained a full kit of hardware and nicely laser-cut woodwork.
Disappointingly there is no profile jig for the leading edge, or even a picture of what one should look like - I will attempt to make my own.There’s a good single-sheet full-size paper plan showing the wing and tail construction, but for all other build information you have to visit the Angelwings website, which contains an excellent illustrated guide and a link to Nick Chitty’s instructional YouTube videos.
I found the tail surfaces and fuselage went together very quickly, but I have hit a couple of snags with the wing. Firstly the mainspars are 3.2 mm thick (1/8”) but the corresponding notches in the ribs are only 3mm. So all 42 rib notches have to be modified, which takes ages and is difficult to do accurately. Secondly, the online instructions suggest pinning the mainspar and trailing edge flat on the plan, but this would make it impossible to achieve the required droop at the trailing edge. Apparently most builders ignore this, but, being a bit anal, I will build a jig of some sort.
Everything else is looking good, but I may add leading edge sub-ribs and find an alternative to the retro rubber-band wing mount. I’m proposing to fit a small electric motor and Sugarwing folding prop, also supplied by HyperFlight.
Usually I would wait until after a few flights before posting a review. However the product reviews have been so helpful to me in glider selection that I choose to post the information at the stage of almost completion. Most reviews of the Eli are very positive. I hope after flying I will love it. The problem is motor installation. I believe all they have done is taken the glider version and drilled the forward bulkhead for the motor mount. I saw many other reviewers used the DYS motor and mentioned it was a tight fit. Actually it will only fit if you take a dremel tool and remove a lot of structure. If I knew in advance I would have widened the front a few millimeters. I notice the new CLM Res 3 is sold in both a glider and powered version. I assume that means its modified for the motor. They are both light and similar structure. If I had it to do again I would be tempted to go with the Prime res 3 or seek Neils advice on the matter.
First, Hyperflight got this thing to Colorado USA in five days. Excellent service Neal. Second, As far as the kit goes it's a well designed thought out kit that should fly very good. The problem is the laser cutting, You'll send some time getting the parts out in one piece without breaking them. Patience is required.
I haven't quite finished the build of the Infusion yet, but so far I am really impressed with the build quality, plans and ease of the build.
Shes got the looks of a fast model with a good presence so I am eager to finish her and and get her airbourn.
Thanks Neil for providing a great model!
looking for an intermediate span glider and so decided to go with a Forza. there are not many reports on this plane, but found the quality to be excellent. as expected and reported in the limited threads servo installation does need thin servos, and a little fiddly for the elevator and reshaping of the clevises. kit is supplied with harness, push rods and clevises. Not yet flown, but eagerly waiting for the right conditions. would I buy again - yes.
Very lite but needs care before applying heat some sections cut to cover wings split before I could apply my heat iron ,to be honest some of the covering seemed not the same consistency. Great product though..held up to the light to make sure maybe just unlucky could be a flaw
The servo frames and arms were a perfect fit, and were perfect for their intended use, flaps and ailerons for an NG2M.
Unfortunately, all of the supplied pushrods were unusable as they were all too long for purpose.
This was not the fault of the product. All of the pushrod lengths were clearly indicated on the HF website, i just did not pay enough attention.
As usual, the service was first class, Thanks HyperFlight..👍
So, please refer to my previous 5-star review dated Jan 5th below. Nothing to change in that review. But, alas, I was attending Joe Nall and decided to fly my Introduction on very windy day. My lack of experience kicked in and I porpoised it behind the "burm" at the electric line. It went in head first and the fuselage and one external wing broke. So, undeterred, I immediately ordered another kit to rebuild what was broken - that's how much I love this glider. Amazingly, I ordered it I think on a Saturday from my RV at Joe Nall and by Weds it was it delivered (UK to Duluth, GA, USA in about 3 days)!! I think maybe the folks at Hyperflight felt sorry for me because my first one didn't come as fast (LOL). But super service. The glider is rebuilt with some improvements (expanded hatch per this youtube video I found: https://youtu.be/LeRUmLoDva8?t=154 ). I re-maidened it today and it was magnificent. Love it. Thank you Hyperflight and Gruner.
This motor was purchased for an F5L model, in this case an Eli. I wanted a motor that would give a really good climb even with full ballast using a 2 cell LiHv 70c battery. Combined with a 10x6 GM prop it gets to 100 metres altitude in 15 seconds with 130 of ballast on board. If I used a lighter motor I’d have to add some lead to the nose so it makes sense to use this one. The 25mm case is a nice fit in the fuselage. This motor, plus Dualsky X30 Esc. with a 10x6 prop and a 2cell battery is a great combination.
I purchased 6 of these for an f5k build as they seemed perfect spec wise and they are, well the ones that worked anyway.
3 out of the 6 are completely dead and a 4th has a really bad glitch so will not be used.
Now I'm going to add I had modified the leads of the servo's (killed my warranty) but this is kind of standard to get rid of unwanted excess wire and connectors, I'm also going to add I'm a electronics/communications Eng: so I'm not bad with this kind of thing.
2 of the servos are faultless, perfect, really fast and I mean really fast and they re-centre every time back to perfect centre... so why do 4 fail and 2 don't please read on ill make it brief lol.
So I did some investigation and found that dry joints on 1 were to blame a friend of mine had this exact same fault but the others were a little more complicated.
The potentiometer internal of the servo has a fault, either a crack or break of the internal bored (i'm not pulling it apart to look) it'd need a microscope to find it, I do have the equipment but i'm not overly bothered as I know what the fault is and couldn't fix it resistor even if i opened it i'll just change the pot at some point or keep them for spare parts.
Now the amazing bit..... All of the above and more was reported back the CHA them self's and the response was nothing short of fantastic and there's many companies that could learn from it.
The reason...... not a quibble infact offered to send me some servo's as replacements, I didn't have to ask or beg they offered straight away now that's customer service, Patrick at CHA was so helpful and did everything he said he would do no Bulls*** said he would sort it out and get back to me by the Monday Am and did, my servos are on there way to me.
This sort of thing does not happen often and is totally out of the control Hyperflight and the most part CHA themself's.
all's well that ends well.
Bought these booms fof Free Flight contest models and noticed that they aren't straight (about 1.5mm out over 800mm lenfgth)- post- cured off the mandrel? No problem so long as you're aware and presumably irrelevant for their intended RC use.Otherwise very nice, quite stiff for the weight, nice hard cure.
2nd review entry, now flown it a bit more. Loving going to the local field in a lunch break and having a few flings. This is my first DLG. Already getting away from 15 - 20m launches to 45m and 5 min flights. Now I am getting the hang of it, I expect to be getting much longer higher flights soon. Such a loveley and rewarding gider to fly. https://www.youtube.com/watch?v=4Iz04pI5zEU
Not impressed. I was using with a standard servo arm (as per glider manufacturer build log). The first problem was once the clevis is installed that then interferes with one of the screws so I could only use 3 of the tiny screws which wasn't ideal. Then because they are small I found that once I'd removed the screws a few times while fiddling with the install that I'd somehow stripped the thread in the frame for another screw. So the servo is now only held in place with 2 screws (and the bearing end). Ended up putting a bar over the top of the servo to help keep it held in place by the bottom wing surface.
I don't normally bother writing reviews because most of the stuff Neil sells is good stuff, but this appears to be one exception. I'd probably have been just as well off using simple wooden ply frames.
What a superb quality kit! Drawings are a work of art and the parts super accurate. German instructions incomprehensible but the English translation available through the Hyperflight link is perfect. Assembly is easy if you've done anything of the FxRES type before, but even if you're a novice builder it won't present too much difficulty. The only small criticism of the model design is that there is no easy provision for ballast and at this light weight it will be needed in anything over a 10 mph breeze. I moved the fuz mounted servos forward to the bulkhead which creates a space of about 35 x 35mm on the c of g for the depth of the fuz. I plan to make up 4 or 5 x 35x35 square lead plates with a centre hole and thread them on to a bolt installed under the wing seating. It means leaving a hatch in the bottom sheeting to get access to the area. I haven't flown it yet as its awaiting wing covering but I'm sure it will go great!
As per usual from Hyperflight, this was through the letterbox the following morning. Great!
For those suffering from servo ‘tremors’ due to a receiver’s telemetry signal, I can say that this servo is totally immune to this common issue with more ‘budget’ similar sized servos, and especially when using Frsky (or even Jeti) radio.
These are high quality motors, I really like the rear cable entry and it being fully encased, outrunner performance with inrunner peace of mind when installed close to batteries in a small fuselage. Pulls 15 amps at full noise on 2S, 9.5 x 6 prop, own design 2m T tail pod / boom glider, AUW 810 grams, climbs effortlessly at half throttle on the stick.
My Alpenbrise is now built and flown. The build is straightforward if you have built a composite glider or two before. Some of the supplied servo frames didn't fit my servos so I cut from ply. As is normal for such models, the clevises need to be ground with a Dremel to clear the hub of the servo arm, also the slots in the upper wing skins (where the pushrods exit) need lengthening and widening to clear the pushrod and clevis. Wings come with recesses in the lower wing skins (but no holes cut) for dual servos on each flap, but no pre installed horn on the flap for the second servo. The flaps operate just fine with one servo, I dont see many people going for the dual servo option so omitting the second horn is very sensible. Fuselage is cavernous compared to most high performance gliders, Rx and battery are lost in there. Ample room in there for a battery/motor and ESC if you went the powered rout.
Mine came in ~4.3Kg (standard 'S' layup). It needed ~600g of lead in the nose to balance. It's got real presence in the air, a good turn of speed, very responsive and decent roll rate for such a big model. At well over 4Kg It's no 'floater' but does ok in lower lift conditions due to it's high efficiency. Handling has no vices that I've found so far, no tendency to drop a wing despite those narrow chord tips. Crow break is very effective making landing a breeze. The recommended 104-108 mm CG range is 'safe', I think I will try edging it slightly further back but the recommended position remains a good starting point.
It takes ballast both in the supplied fuselage tube (3/4" dia bar) and in wing pockets (5/8" x 3/4" bar). I'm still waiting for the right conditions to try it with ballast, I expect it to be ballistic.
I’ve used a number of Dualsky motors in my own models and those who I build for.
This motor is fitted to an “Eli” F5L model. Powered by a a 550mAh 70C battery and fitted with a 10x6 GM prop it gets to 100 metres altitude in about 15 seconds. Model weighs 460 grams. I can use that excess time to fly upwind when the conditions need it. Pulls about 16 amps max.
I recently purchased this model and want to give a flying review. I have now had several flights and can only say can this model performs WONDERFULLY - BIG YES.
My first flight said it all. I found very light lift and dropped thermal flaps and there was no stopping it. One of the best flights of many. I tried it out on a windy day and reflex proved very positive. Drop flaps and you can walk faster. I am just a sport flyer but this made me look good. If thinking about one do not hesitate. I have loved every minute.
Superb service from Hyperflight, and a fantastic little DLG. Easy to build. Mine came in at 166g (Receiver still with case on, and altimeter and vario).
After getting the hang of the discus launch, I can launch comfortably to 20m, and today caught a thermal and climbed up to 42m, very satisfying. The Dart seems efficient, and very well behaved in the air. Fully recommend it! Mine is the glass lay up.
The Yoda came well packaged, with lots of bubble wrap in the box and with a solid box for shipping. Shipping didn't take long... about a week.
The Yoda itself came in perfect condition. No dings, no scratches. The model itself looks amazing. The instructions for the build are a bit rough, but I should be able to get it done. I haven't had time to work on it yet.
I used these on a mid-sized creature for the upcoming Super Girl movie with a Plat-cure silicone skin. Although small, they not only moved the skin with sufficient force, but after running constantly for over an hour during a press junket, proved to be super reliable. Hyperflight is my go-to for any small servo that needs to be reliable and delivered promptly with good aftermarket suport.
After several discussions with a few club members regarding folding propeller and power systems, I sold the CN spinner and blade I had originally planned for my Nan Explorer 3 (that I got from Neil last fall) and switched over to the GM spinner and blades. I just completed my install of the motor and metal motor mount on my E3 and I could not be more pleased with the results. My E3 (3.8 V tail) will tip the scales at about 51-52 oz. and my first power test resulting 375 watts at 34 amps (3S battery) on a GM 11x6. For my style of flying (read that as old age) this combination will probably be just perfect for me and I am looking forward to flying this beautiful sailplane.
I needed a different collet size for my Nan Explorer 3 that I got from Neil last fall. I was having trouble finding one stateside and I wanted to keep my assembly of the E3 moving, so I ordered one from HF. But since it seemed silly to order just a collet, I also ordered the Prime lll kit as Neil had a good price on it. Kit and collet arrived in Colorado on the 5th day after placing my order. I have built at least 10 different F3L and F5L kits in the past two years, so I've had pretty good exposure to some really excellent products, but this Prime kit is, in my opinion, one of the best I've seen so far. Wood selection, hardware, plans, and laser cutting are just excellent. The model has several unique assembly features that I find very clever. I've only just examined the kit contents, but I am looking forward to building and eventually flying this beautifully crafted model.
I have been assembling my Nan Explorer 3 that I acquired from HyperFlight last fall. During this time (and due to some input from other club members) I changed my plans for motor use on this model which made the original 6mm GM collet unnecessary. I had some difficulty finding one stateside, so I ordered this one from Neil. It arrived quickly (along with a new F3L kit) and has allowed me to get my power system installed and another step closer to completion.
