I have now had some time to fly the Ultima 2. It is without doubt one of the best planes I have flown. It is easy to fly, shows thermal well and circles well in thermal. I fly with the CodG well back but that has given no problems, it can almost stand still in the air, or go seaching for lift. I does not seem to have any vices, I have not found any so far.
The finish is great, up to a very high standard. I had to install a new rudder pushrod as there was not enough clearance between the two pushrods, but what was due to the servos I used.
I do not hesitate to reccommend this glider.
Short: Nice model , needs printed instructions and clear pictures.
Finish of the model is very nice, and the carbon is nicely done.
I used MKS servos which do not fit in the tray provided (kst servos fit well), so i made my own tray.
I did have issues with installing the control surfaces springs, i followed the build on the RC Groups thread but they were not very obvious for me, and the pictures were not great (on example is the picture of the rear fin , which as it is taken directly from above it is not clear which side the control horn is meant to sit).
The screw holes in the wing did not line up with the fuselage holes so I had to Dremel the hole out a bit.
It would have been a lot more enjoyable if the kit came with a printed set of instructions , which I thought at this price point would be a given.
Flys very well, it has a very neutral response with air speed and it is easy to find lift as the wings give a clear indication . It can thermal on a dime.
After a bit of test flying i found moving the cofg forward to improve the performance and give a obvious indication when close to stall.
I'm new to the 1.5m DLG class and decided to get the Auri based on reviews and a thread on RCGroups. Being my first quality carbon aircraft, I was initially a little intimidated by the build, but it went together surprisingly easily. The wings and fuselage are stiff, lightweight and have a very nice finish. With 4x KST X08 servos and a 2s 300mah lipo, the all up weight is 236g (5g of lead in the nose) and wow does it fly nice! I followed the setup sheet for the control surface travel (but CG at 66mm) and it flew extremely well on the first day out. My launches need some practice, but after just a few slow practice throws, I caught my first thermal which lifted it almost out of sight! This will definitely my chosen model on a calm summers day!
These are great servos for the fuselage on high performance gliders. I just about managed to get them to fit a strong Freestyler 5 and 6 but had to Dremel some of the fuselage where the servo corners are. One thing to watch out for with these is not to let the receiver battery drop to a very low voltage say less than 3.5v-4v as the servo output does a full 360deg turn which can damage linkages that are connected.
This is a nicely sorted kit, and as usual from Neil, packaging and postage were first class and quick. I built mine as an electric powered plane using the recommended ADH300L motor and will run with a 3S 450mAh battery. I found the model was quite nose-heavy (having been originally designed as a glider) and chopped a 60mm plug out of the pod between the equipment hatch and wing LE before covering the pod - using some plywood (and glass) reinforcement at the butt join. Then the completed model balanced perfectly at 71mm from LE with the battery up front near the motor. AUW 490gm.
I bought this, (together with the recommended bluebird servos) in October 2020, and it had its maiden flight today. I used a Roxxy 28-34 motor with a 9x6 prop providing just under 100 Watts.
1) Good prompt service from Hyperflight; thank you.
2) Instructions are in German – though well-illustrated. Unofficial translations are available on the web.
3) Balsa quality is good; hardware complete. Nicely drawn plans. Perhaps the circular spar holes in the wing ribs are a little large. Materials are light and it needs care not to be heavy handed when building. It goes together quickly – all the parts fit. The carbon leading edge with iron on covering works remarkably well. Needs care with wing joiners – but the system works well.
4) It balanced at 87 mm from LE, as per instructions, using a 1600 mAh battery and no added weight. Also flew OK with a 1300 mAh battery which was 24 g lighter.
5) Landing flaps are effective – landings are slow.
6) It circles tightly and gains height quickly. It is my lightest and largest electric glider yet, and it thermals better than anything I have had previously. More than once today I had to use flaps to dump height in a thermal. I am looking forward to flying this a lot.
7) Good value at this price.
This is a very good kit - high end dlgs cost twice as much but this is a great alternative if you’re not interested in competition. This is the second one I’ve had. AUW is close to 330g but you can still catch a nice thermal. I would recommend it. I make the canopy opening a bit larger than stock and use a throwing blade instead of the pin. I also use pull-spring instead of the pushrods that come with the kit. All in all, it launches and flies great considering the price! Hyperflight service was great - shipped fast to US.
I bought a couple of these to replace the 2 Bluebird AMG's in my Elf because the constant buzz of the AMG's finally pushed me over the edge. The KST06's are totally silent and just about fit into the Elf with the lugs still on (with some trimming of the very central leading edge. Lugs left on because I'll rob the servos from the Elf later in the year). I'm quite happy to give up a couple of grams for the extra quality that the KST's offer over the Bluebirds
This is a great plane. Construction was straight forward. I did install 1.5mm carbon pushrods and micro control horns instead of the string/spring system. Even with the pushrods, total flying weight is 189 grams.
This is a great flying plane, it's my first DLG, and now I'm hooked!
The kit goes together with the precision of a Swiss watch. Everything clicks snugly into place, except the empennage. I was puzzled by the wood choice—I could identify little moderate weight wood and no C-grain, so things were a bit crumbly, especially the empennage. I found it useful to flip back and forth between the Pike’s Peak step-by-step instructions, glidermang rcgroups’ build log, and Google translate of the included German instructions. I have not high-started it, and my electrification ultimately failed (see my review of the kit), but it flew well from the ground.
Excellent service from Hyperflight and a good kit of the Fresh RES.
Unfortunately I could not find the parts F28 and F29 so made them from scrap 1mm ply.They are mentioned on the plan but seem to have been omitted from the 1mm ply sheet.
HyperFlight comment: Very sorry about this. Thank you for making the parts up yourself. We have taken this up with the manufacturer.
Tried my servo out today. I had a problem with the elevator trim wandering when using a cheap servo, my F3 RES glider would creep into a stall and over speed in the same flight at the same trim. This super little servo has solved that problem and suddenly the model can be trimmed to a consistent slow speed and now defies gravity like those amazing HLG videos we see.
Packaging excellent and arrived within 2 days. Thx Hyperflight
The motor is installed in a:
Windy Maxa at 2.23kg, 78.6 ounces all up,
Battery is a 4S, I'm running two types an 850mAh (Daves Toys Australia) and 900mAh black Hyperion.
11 x 7 Vladimers prop (A beautiful-looking propellor).
60 Amp speed controller. (set it to soft start)
Goes very well in both level and climbing flight, I am really impressed. It pulls about 53 amps in level flight based on battery recharge calculation ignoring losses and climbs at 10/14m/s.
Bought the new “Mini Dart 2 1m DLG”, my first DLG. I am very impressed, the quality of all the contents are 1st class. Everything fits perfectly, the finish is really nice. This is an easy build, the fuselage is nice and wide and accommodates the 4 servos on the provided tray very well. You will need to use micro servos no wider than about 9mm (those recommended are ideal, as are the batteries). The delivery as always is very quick, well packed and in a sturdy box.
Super Produkt für meine R.E.S.- und E-R.E.S.-Flieger: leicht und leichtgängig. Über die Gewichtsersparnis und Tipps zum Einbau in FMT 6.2021 in meinem Bericht über die Eli. Sofort versendet. Die Zeit auf dem Versandweg hielt sich - trotz Brexit - in Grenzen (ca. 10 Tage).
Great product for my R.E.S.- and E-R.E.S.-flyers: light and smooth. About weight saving and tips for installation in the grat german magazine FMT 6.2021 in my report on the Eli. Immediately dispatched. Despite Brexit, the time on the shipping route remained limited (approx. 10 days).
1st off I marked it down one star as my kit came incomplete. 1. I only received a manual for the body and tail no details for the wing. I did source a complete manual which Neil has put on his site. 2. I had full plans for the wings but no full size plan for the body (which would have been handy for shaping) 3. Some small parts were missing (some dowel and a couple of small rods and connectors) these I had in my workshop so no problem. Having said the above I received in my kit some parts that were not part of this kit.
All though it sounds like I am disappointed far from it the plane is nearly finished and looks really good.
One thing I would say is that if you are not ok or this is your first build this Not an easy build Google translate from German is not the best read. If you can build from a plan only you will have no problem.
Well I just had to have another one, just received my second Enigma from Neil.
The finish quality and fit are just superb and cannot be faulted at any level.
It is a joy to put together the second time and the lessons learnt with No 1 helped immensely. I do wish that the firewall was not drilled at all, rather than the four bolt holes, better just to have the central hole so that three bolt fixing for reisenhaur gear box can be achieved with good spacing.
I have now had some 8 outings with the No1 model, and it is an absolute joy and revelation to fly, indicates lift brilliantly, it is also much easier to repair being of solid cored construction. I have unfortunately had several radio failures with it, which has now been traced to faulty lipo’s no reflection on the plane but is beginning to look like the most battle scarred glider I have ever had, not bad as it’s only a few months old, it does break, but I have found it is well easier to repair than hollow moulded construction. It does not look pretty now but still flies beautifully.
Certainly the model of choice if we ever get back to comp flying in 2021.
Ordered late afternoon and delivered just over 24 hours later. I've looked longingly at the plan and the kit components but am not yet ready to start building. The quality of the balsa and the part-cutting is very impressive. The English translation of the build instructions is a little challenging but I think I've worked it all out. "Controll turning of the wing, on tip-1 negative 1-2mm ......" was particularly challenging but I'm assuming that it really does mean washout.
Hyperflight have a fabulous selection of kits and their response to customer orders is second-to-none. I know that obtaining balsa kits from Europe is very difficult at the moment and I hope that will be resolved because I look forward to building more of these.
HyperFlight comment: Yes it means washout.
I had a spare A20 Hacker motor and 30a esc and looked round for something to fit them in that involved a bit of building. It soon became clear that the Inside could fit the bill but I also fancied a carbon boom/pod fuselage as I liked the look of the AVA Pro-e.
I contacted Neil and thanks to his excellent advice, I now have an Inside f5j married to a carbon pod/boom fuz. Regarding the Inside, the plan was informative, well drawn and the laser cut parts so precise that it it was a joy to build. Similarly, the appropriateness and quality of the fuselage parts/servos provided by Neil were first class. I am very grateful to Neil/Hyperflight as his advice and ability to supply quality components was key the the successful completion of my project.
With test flights successfully undertaken, it is time to give my thoughts on the Purito Electric 2 Meter RES Glider.
Supplied by Hyperflight, along with the Blue Bird BMS-101DMG Servos, the final launch weight is 465 grams. I have to mention, these servos, while not cheap at £18 each, are very very smooth.
Power is supplied by a Hacker A10-7L motor / gearbox combination, turning a 13” x 8” GM Prop and Spinner, power output measured at 9.5amps / 105 Watts on a 3S 350 mah Hacker Top Fuel ECO-X Lipo.
This battery was chosen as it gave the C of G at 75mm from the leading edge and proved a great choice in flight. There is no problem to get 90 seconds of full power running with only about 135mah taken from the battery.
90 Meters is very easy to obtain in less than 30 seconds, although the transition to smooth level flight is going to take some time to master, after flying high powered 4 meter F5J models.
The rudder is currently set at 70% Expo, and is still too fierce, some more work required there. Very slight input to rudder or elevator is all that is required, I think dual rates will need to be set up.
Very long floating glide and the slightest lift at 9.00am on a cloudy morning, saw a rapid climb out, very easy to achieve.
A lovely model, I can’t wait to fly it on a hot summer’s day.
The delivery by Hyperflight is excellent.
As mentioned by most, this kit is absolute quality and the parts fit perfectly. Given the kit seems to have found its way to the USA and Australasia I am surprised the instructions haven't been officially translated from German. The translation for the Inside F5J differs significantly after the centre section of the wing is complete. The sheet and part numbers are different and it means following the German version. They use symbols for gluing so it is quite intuitive. Once you have completed the centre section the same process is followed for the outer sections.
Having covered the wing sections I would highly recommend that all the surfaces are sanded to remove the charred surface. In covering the main section the covering started tearing away when stretched because adhesion to the burnt area was very weak.
For the price this kit is an absolute steal :)
Looking forward to getting it in the air.
Glad I got theese bags to stop hangar burn. Clever design and perfect fit.
I’ve been researching affordable hotliners and pylon racers for a while. All my research pointed to the Jolt 2.
Unable to locate one in the United States, I came across HyperFlight and found the exact color combination I was looking for. With a bit of hesitation, I hit the purchase button and expected a long wait to receive my bird. Literally within and few days, my package showed up, with zero damage on the shipping box and the plane perfectly packed.
As I unpacked the Jolt 2, I was amazed at the quality and craftsmanship of this plane. The finish is smooth and flawless, the fit spot on and nothing was warped or damaged in any way. The colors are vivid and stand out.
With my busy schedule I have not completed the assembly, but I can’t wait to finish it.
I’m not looking to race competitively, but looking for speeds around 160mph and something that turns heads, so to speak.
HyperFlight - great job on an awesome product. I’ll definitely be a return customer!!!
Thanks Neil for your quick communication and professional operation.
A beautifully manufactured quality motor. I have only so far performed static testing on it but from these figures alone I think this will be a cracking F5J motor exhibiting excellent dash time and rate of climb in windy conditions where ballast will be used.
How its possible to design/manufacture such a small powerful in-runner motor is impressive. My static tests on 4S 850mah 80C battery with a 11x6 GM prop showed it giving 63A @985 Watts with min pack voltage of 13.4v. 60A is the recommended maximum continuous current draw for this motor but in actual flight this is likely to drop to around 50-55A with this battery/prop combination. Wont know for sure till I flight test it but experience tells me that in flight it should be under the 60A mark meaning that the recommended prop of11x6GM is probably about right. If you want a little more head room use a 10x6 or a10x5 GM Prop.
Starting at the beginning, the kit was well packaged and arrived promptly.
The quality of the material selection and the laser cutting is outstanding, parts fit with little or no reworking making the assembly of the model fast and a joy.
The plan is clear and comprehensive, the instructions although in German give a graphical guide, and English instructions for the Inside F5j, downloadable, cover most of the build .
Build threads on YouTube are worth watching.
First test flights confirm the model is easy to fly and I am looking forward to relaxing days thermal soaring in the summer ahead.
When the aforementioned orange and gray Auri arrived, my girlfriend and I opened the box....I noticed that she was eyeballing it heavily....she liked the checkerboard carbon on the wing!!.....so....I went back to my shop and ordered her a pink and gray one....When we opened that one up, we noticed some of the small parts were missing...we sent an E-mail with a photo of the small parts that did come to Neil...in a couple weeks we had the parts...Great service!!!...Now to build and fly!!!
While I greatly appreciate having wing bags for my Auri, these are a very tight fit which causes tearing after a few uses.
Very fast delivery... ordered at noon and posted the same day... took 7 days to arrive in Belgium... customs delayed the delivery a bit
Use this prop on my u-glider on a 3300kV motor with 2S battery...
Had to slightly adapt the prop ...
Works very wel, much better than the original cheap plastic prop and less noice...
