The RES-olution Elektro is the electric version of the RES-olution V2 F3-RES model, and like the glider it is a quick building easy to fly laser cut balsa and carbon glider kit. Developed from the well regarded Climaxx design the RES-olution Elektro makes a very good entry level 2m eletric RES model. Its robust structure features approx 10mm tubular carbon spars which ensures it copes better with the rough and tumble of club flying, and allows it to excel in windier conditions than the other lighter models we sell.

The hand selected wood in the RES-olution Elektro kit is beautifully laser cut and is a pleasure to work with. All the balsa and ply wood parts are precut making assembly quick and straight forward, with a minimum of sanding required. With a flying weight of approx 700 g (24.7 oz) the wing loading can be as low as 21 g/dm2 (6.7 oz/sq ft). Despite the low loading the Selig S7012 wing profile gives the RES-olution good penetration, allowing it to be used at higher wind speeds.

The kit includes all pushrods, all small parts, a colour full size plan and richly coloured, illustrated, building instructions (in German). Not included in the kit are adhesives, or RC components. For covering Oralight is highly recommended.

  • Laser cut all-wood construction with self jigging weight-optimized parts.
  • Two-piece wing with multiple panel breaks and pre-carved wingtips.
  • Carbon tubular spar for easy construction and good strength.
  • Front riblets to reduce covering sag and increase laminar flow over the wing.
  • Two powerful spoilers give an excellent braking effect and accurate landings.
  • Ample room for a 28mm diamter direct drive outrunner motor for economic power options.
  • Colour plan and extensively illustrated, with detailed building instructions (in German).

A very efficient electric model. Building instructions are in German but with the excellent diagrams are not difficult to follow. Kit parts are very accurately cut, and only a little fitting is required on things like wing joiners. Anyone with some building experience will find this a quick model to put together. Flying is a real pleasure. Spoilers at about 60 deg. give a nose down trim, making landing easy.

RESolution Electro

Having built two Inside F5J's, I can say that building the RES olution was a real pleasure. As with the Inside F5J the quality of the wood and the laser cut parts do not disappoint and yes it goes together like a watch. As for how it flies, IT IS THE BEST FLYING 2 meter I have ever build. The air foil performance and light weight come together to provide great endurance flights. With that said, I had to build by the photos because there are no English plans you can print out or download. I had asked Hyperflight if English instructions were available in a PDF like the Inside F5J and the response I got back was short and to the point, " no". A suggestion to Hyperflight would be to make a downloadable English instruction pdf for the RES olution. An inexperienced American builder might have some problems with this kit and lots of beginner pilots and builders like to start out on 2 meter kits.

Superb Radian upgrade

I bought this as an upgrade to my Radian I am no expert pilot or builder and even though the instructions are in German the pictures are clear and the build very clean and straight forward everything fitted very well and there is very minimal sanding required. All joints were a great fit I used thin and medium Cyno with some pva.
To fly it is a totaly different experience to the Radian a much more refined flight and crisp performance. I found lift easily and it only needed a little to gain height effortlessly.
Very pleased with it an now looking forward to many hours of fun.

recently purchased this model and have commenced building the wing. Once assembled, the structure is surprisingly stiff even before covering. I did find one or two slight problems- the instruction are in German with no sensible translation, even from google. The outer wing ribs are numbered out of sequence, in addition I cannot see the need for such a heavy gauge wire wing joiner. A cf rod would be more sensible. The tailplane and fin would benefit from some lightening holes but I'll check the balance before final assembly. The wing trailing edge is assembled rather differently, I'll be interested to see how the covering turns out.
