Review by: Geoff GriffithsA Joy to build
I'd seen one of these fly a few weeks back and was seriously impressed by the performance. The kit arrived very quickly (as did the other odds and ends I've ordered, thank you Neil) and within a couple of hours I'd completed the tail feathers. That was the easy bit. There are no step by step building instructions, these need to be downloaded. At this point I'd add that if you are fluent in German, I'd be inclined to use that version, sadly mine is not all that good so I was stuck with the English translation. It's a bit quirky in places, so take time to make sure you understand. The actual build is a revelation in how it should be done. Everything is built on a jig. It really is more engineering than model building and very satisfying. If care is taken to ensure the ribs are sitting in the jig nicely it's virtually impossible to build in any warps. The only tricky bit is the spoiler servo arrangement. I used the tiniest Ripmax servos with home made extension arms and that works well, but it's necessary to extend the leads. I replaced the leads at the servo end. (very fiddly) These then need to be fed through the small holes in the ribs before the plugs are fitted. Having glassed just the nose using lightweight cloth, I've fitted the little geared Hacker as recommended and are now at the point of covering the wings. An absolute joy to build so far and I'm very much looking forward to getting it in the air.
Review by: David SpainPurito is a competitive competition model
Had not flown this model much before a large Australian ERES comp. Flew my other known competitive model in tough conditions and crashed it. Went to Purito in difficult windy, low lift and gusty conditions. It was rock solid and next three rounds were 1000 pointers - cant speak highly enough of it, picks any low lift. Is controllable in difficult conditions. Placed 5th overall in large field after some prior poor rounds. The construction is a great example of good German engineering. It is almost impossible not to build it straight! The other good plane at the event was the EMedina or OzeRES V 2. I have flown neither but building an OzeRES 2 now. The Medina and OzeRES V2 are respectively an ARF and typical build yourself kit of same design. Great to see evolution in eRES models is ongoing.
Review by: Arnold PaikinPurito E … wot a jol
Built this amazing kit and flew it today and what a pleasure … 10 second motor run and it flew straight off the launch … Compared to my 1st build in 1970 … Graupner Amigo 2 … the quality and accuracy of the construction of the Purito is first class … gone are the days of pinning the spruce spars over the plans and and and …
Review by: BrettPurito-E 2m RES
Late last year I built the Purito glider kit along with an additional electric fuselage to give me both options with only 1 wing. This did, however, involve building a duplicate horizontal tailplane, because this is not supplied as part of the electric fuselage kit. No problem, as the parts and layout are shown on the original glider plan. The effort was definitely worth it, as I now have the best of both worlds!
The electric version was maidened very recently in extremely light airs and was an absolute delight. A worthy competition model indeed - or just great up the hill. Having the option of electric 'get out of jail free' gives additional confidence to be more adventurous in exploring unpromising conditions. The Purito-E excels in these sort of conditions and so you rarely end up needing the power anyway. A very gratifying model that I doubt will be easily beaten for fun and performance.

Delivery time was fast and all in good order, Thank you to Neil.
Currently build is underway. Thought I couldn't find a kit quality better than the "Inside F5J" but the Purito is just that much better with CNC routered parts.
Going together with great precision, looking forward to flying it when complete.
Build instructions and build threads are very instructive, but being "old school" still like a set of plans, just a personal preference.
Review by: TrevorPuritio-E
Purchased this model as an addition to my "2m RES electric fleet. As usual the service from Hyperflight was excellent. It is a most unusual kit in that there re no plans supplied with the exception of the tail surfaces and the spoilers. That said, I am about half way through the build and it it goes together very well. There is an english instruction manual translation available and this together with the build log on RC Groups makes everything very clear. Looking forward to completion. Will use the hacker A10-7L motor/gearbox. Also thanks to Graham for his review, which is helpful. Looking forward to the fiorst flights!
Review by: Graham LorimerFlying the Purito Electric
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.
