It has a very light, already covered, built -up wing with, what looks like, a carbon spar with light balsa ribs etc. Come's with a very nice, very light, GRP fuselage with carbon reinforcement. Images above from Hyperflight.

A friend has one of these and it flies really well in light winds on our slopes so I thought I'd get one. Have not seen much online about them, so thought I'd put some phots up as I assemble. Bought from Hyperflight in Sept 2021 and only getting round to it now!

Thanks for the encouragement guys. Last weekend there was no wind on our slopes in the Pentlands, but this Sunday looking better 🙂

Well, can't believe it's 10 months later. I did take the F86 up a couple of Sundays later when the weather was kind of ok, but when I was assembling it I noticed the the power to the RX kept on going on and off(!) Extensive fiddling on the hill revealed a intermittent connection somewhere, but could not localise it to connectors. I wasn't very happy with it as I was spooked by first flight, doggy RX power, and had difficulty not mangling it on our long walk in strong wind. 😞 However, last Sunday, I took it up with new battery pack the new 1" further back CoG and it flew a treat in about 8mph. It's 1050g with no ballast, and still flies smoothly and reasonably fast. Still needed quite a bit of up, so will move CoG back a bit further. Pretty certain tail incidence is not correct - should of gone for the all-flying tail! Think this will be a keeper 🙂

Thanks MattyB, yes we thought the 3D print would be too fragile too, but the first one outlived its wing(!). The fus is quite short and has 5-10% infill (circa 250g) so is surprisingly robust. The sheath nose is fragile and cracked after a very fast impact, but was easily super-glued back together. A friend has a 3D printed spit - and it is fragile. This is very tough in comparison.

Apologies for not posting as I built - just seemed to get carried away 🙄

Apologies for the rapid fire posting 🙄

Done, and flew well today in 35mph with 9x63g ballast (empty weight = 800g).

reprinted fuselage as taped ailerons on before refitting old glued-together fus. which would not fit over taped ailerons! (must get better arrangement for taking fus on and off(!))

Protected wing with endcaps this time (3mm light-ply sandwiched between 200gsm carbon) should of added better gussets(!!).)

Holding spar down against PU using balsa bridges as in Uber Raven build (and remembered protective tape this time!)

Had old, cheap (non-wing) servos from previous build, so went with these, but proper wing servos would be better.

Similar for 1 piece spars from Decathlon

Routing ballast tube hole against a straight edge:

Glued wings together using contact glue for foam, PU for wood - seeded to work 🙂

Carefully sanded foam and shaped LE (I always ding the foam when sanding - so trued to be real patient, not one of my strong points ...)

Sub-TE is 6x6mm balsa glued with foam contact adhesive (this is great stuff). Sub-TE is just to provide nice edge to tape ailerons.

LE is 3mm cedar to make a bit more ding proof:

remembered to protect beds this time as PU seeps through EPS and partially glued cores to beds last time (eek!)

Ballast tube take 11 x 63g slugs:

Started (re)building a 60" plank 3 weeks ago. So thought I would post some pics (selfishly to remind me build). Fuselage is 3D print from here: https://github.com/timdrysdale/fvs60 Wings are hot-wired EPS with wood LE & TE + carbon spars, covered in laminating film.

Added some more decoration. Moved CoG back by 25mm so should not need so much up trim but still suspicious of my tail incidence. Weighs circa 1kg, flew with 300g ballast added and weight fine for our hills. Will take max 550g ballast. Will take it up hill on Sunday weather permitting ?

Suspect above is rather old hat to PSS folk, but I got quite excited lol

Use the transfer stuff to assemble decal: Peel off on transfer stuff, apply, and remove transfer stuf ?

Decided to have a go at using a vinyl cutter for the decals. Alignment with transfer tape and star registration marks went surprisingly well so thought I'd post some photos here for anyone who was thinking of doing similar. 1. Create or find SVG shapes, and add some registration marks (stars here) 2. Load into design tool with each colour on separate layer. 3. Send to cutter and then peel unwanted stuff off Cover with transfer stuff:
