Review by: Mr P A BrandrethF5J “Enigma” or aka “Skiff” by any other name
I have to say as I start to pen this review for Neil at Hyperflight, it is not something that I do very often at all, however, I am about to make an exception.
I have had a little experience previously with this glider from a fellow F5J flyer who bought the “Skiff” a couple of years back, and had the wings fold on the maiden flight. Credit to Neil, the wings were re placed and I understand that the wings now include a shear web between the spars rather than just the core Rohacell. That said, the plane looked good, and I do like “V” tails - when it was repaired it flew well.
I had a clear out of the hangar, during this Covid calamity, and was rather disinterested in competition flying, but having cleared the hanger, the bank balance had funds present and I had some servos and a motor in a draw.
I was initially drawn to the price for this plane and then realised that I was looking at the site as if I was based in the USA so the price was ex VAT! Still not bad with adding on HMRC’s cut.
The order was placed and duly arrived next day. Well packed and undamaged. There have been some comments concerning the quality of the finish, my experience was very much better, and on a close look the engineering and finish was excellent and certainly compares to many other of the Eastern European offerings. In fact the quality and fit I would say are excellent, with some very nice touches, including beautiful machined fit of “V” tail to Fuz, ready fitted wiring harness extremely light wires used, canopy fully fitted, even wing servo hatches cut to fit, and ready made up push rods and epoxy cnc cut aileron and flap horns.
Target AUW weight was stated to be around 1475g, mine finished at 1550g but I had 120g 4s lipo and a 105 g motor and gearbox fitted, and it was however the 4m version.
Two points of note:- the built in fuselage ballast tube is 550 mm long and starts from the rear of the canopy opening with roughly 200mm in front of recommended C of G position, and over 300mm behind. This although not yet tried is expected to produce a rearward shift in C of G which is not good. The Ballast tube is bent along its length to get under the wing seat rather than being straight, consequently the ballast slugs from my Pike Perfection would fit into the tube but would only go round the bends, if they were cut into 30mm long slugs. Second point is that the ready made push rods for aileron and flap connections are pre bent – why I cannot understand as they do not assist with servo installation and are now strait.
I purchased two KST X08’s lug less servos for the V tail - MKS 6100s will not fit as they need to be 8mm.
Ordinary KST’s XO8’s with mounting lugs would have fitted. C of G turned out at 110mm i.e. mid-point of recommended range
First test launches followed 2 weeks after delivery, Flight test conditions were not bad but not the best, plus 10 degree C temperature and no wind whatsoever. I tried a couple of hand launches and made some very minor trim adjustments to glide path, next hand throw went for about 200 metres at 1m off the ground, I had to nose it into terra firma before it hit a fence! This was a seriously flat glide.
First couple of powered launches then followed to approx. 100m and an 8 and a 10 minute flight resulted. No height gains were achieved but the sink rate was so absolutely minimal, turns appeared to lose no height at all, handling was crisp and tidy. Landing set up on flaps and the compensation on elevator proved to be totally excessive so landed without flaps and was wondering when plane was actually going to set itself down.
There is only a minimal pitch up trim change from deployment of full flaps.
Overall, I am so impressed with the quality of this glider and its flight characteristics I am looking forward must recommend this plane to one and all.
Addendum the Second day of flight testing now completed, made fatal error and had that “one last launch”, resulted in flat battery and an encounter from 30m altitude, then no control and 70mm into soft terra firma. Resulted in fuz being broken in two places, both wing joiners broken and some creasing to main wings in several places, I was not best pleased but now repaired and waiting for some replacement wing joiners - note to self - change the lipo before having that “last flight” .
Looking forward to getting it back into the air – what a plane highly recommended, it’s a gem at a good price. May well be tempted to another.
Review by: Phil BirdHidden Gem
This model has to be the hidden gem of the F5J world. Fantastic looking V tailed glider at an amazing price. First class fuselage, cw ballast tube and wiring harness already made and fitted. The wings are well built without all the bells and whistles of the show ponies. Assembly and flight review to follow.
Good prompt service once again from Hyperflight. Really well packed, survived the trip to Australia intact.
Review by: Alain Leclercq
Finition mediocre. Dommage. Le planeur vole très bien
Translation: Mediocre finish. Shame. The plane flies very well.
HyperFlight comment: Agreed, the finish could be improved. But the performance is excellent and the price is reasonable. Alain was sent detailed photos showing the finish problems beforehand, and asked if he wanted to proceed.
