|Supra Nomenclature - these are the various terms used to describe the different versions|
|Classic||The original fatter pod, with a removable nose cone.|
|Pro||The new longer, slimmer drooped pod - used on all glider Supras. Now suplied on most electric models. Only very small (Speed 400 size/25mm diameter) geared motors can be fitted.|
|Competition||The model is fitted with a built-up tailplane (horizontal stabiliser) and rudder. This results in a slight reduction in tail weight, reducing the model's total weight and inertia.|
|Expert||The model is fitted with lightweight spread carbon molded tailplane (horizontal stabiliser) on a short tail pylon. This reduces drag and improves the model's stability and pitch response.|
|Ulralite||The wing has a reduced strength spar and glass wing skins - lightest, but suitable for low energy electric flight only.|
|Spread Carbon||The SC (also called ST for Spread Tow) wing has a full strength F3J spar and spread carbon wing skins - very light and very strong.|
|Glass||The wing has a full strength F3J spar and all glass wing skins - light.|
|Carbon/Glass||The wing has a full strength F3J spar and carbon skins on the centre panel, and glass wing skins on the tip panel - medium weight.|
|Carbon||The wing has a full strength F3J spar and all carbon wing skins - heavier, but very strong.|
Review by: AnonymousSpring an many flying hours on . . .
OK . . . its spring, my flying review. I was not to impressed with the Supras fusalarge arangement cockpit size etc, I made a number of mods including a replacement AVA pod/boom. At the end of the day I have finished up with the original fusalarge modified with a second cockpit cut between the original and the wing mount pylon, not priety but functional.
So how does Supra perform. I love the wing servo arangement, servoes can be replaced in just a few minuets, on the field if necisary! The 6100 servoes are a little delicate and vunerable on landing if you dont get the flaps up in time, I have done two since January!
Despite my inadequacies what about the flying ability of Supra. Frankly it is briliant, as I get used to it and adjusted the trim more to my liking, I prefer the CG a few more mm further forward than that recomended, a personal preferance.
The speed range is remarkably wide. Into wind, she can be held as though she were a bigger span, lighter loaded machine, that extra few mm of CG is helpfull.
Low level thermal sniffing is excelent, get the wing tip up, and keep the speed on, she flies away, doubling your height in no time. I have found no issues with tip stalling or nose droping that cant be anticipated. One is also impressed with Superas thermal indication, fly into a thermal and the nose lifts, even the lightest of thermals are visable, the same for wing tip and side slip indication, streight into a turn and away you go!
Flying gets 5+ stars in my book, just a poor fusalarge arangement . . . in my humble opinion?
The flying is so good, the envelope so wide, my 4m Pulsar and 4m Ava have stayed in the car.
Review by: AnonymousExperience needed . . .
‘Supra has been around a long while, in various modification upgrades, currently I love the way she flies. If there is lift about she will find it and show you where it is. I have found that she will scratch on a gnats **rt at 20ft, producing tight thermal turns without the hint of a stall. I am currently investigating why she will do this and think I have worked it out.
. . . On last approach 30 seconds to go, another model on the same time and in the same air, throw a tight thermal turn with confidence and you have the ‘time’, just make sure you have the spot. As I say after todays session I think I know why Supra can do this . . .
However, when one pays £1000 for a moulded e-glider kit one expects things to be right, the wings are right, the tail is OK, but the bit that holds them together as a flying machine needs a serious revamp on dimension and better use of available space and access in view of modern and recent component availability . . . ? Experience stepped in and ‘I made what I had, work’. As a first moulded composite F5J, one would have been asking questions.
. . . that said, I cant wait for some warm weather so that I can get the trim spot on and really see what I can squeeze out of Supra, despite the difficulties and unsightly surgery that had to be done.’
Flying performance is worth 5 stars, the present fuselage can only rate at 4 stars.
Review by: Marc
Kit looks very well manufactured. I have the mini graphite, the graphite, super ava etc and this Supra kit is also designed very well.
Unfortunately it arrived damaged and incomplete. The damage was not caused by transport, because for/during transport it was packaged very well. One of the corners of the flaps was broken/damaged and also the tailboom had a tear of 3,5 cm at the beginning.
Some parts for the battery-tray were missing.
We subsequently tried emailing the customer (three times) but have not had a reply. We will be happy to resolve this if given the chance.
