The area where the battery sits looks a lot narrower than the S800, for example. Could be difficult to get the CG correct, especially if you don't put an HD cam in it.

Had to 3d print new motor mount. Average quality ply for motor mount delaminated itself merely screwing motor in with supplied screws.

Used Velcro to hold front epo cover on. Made hole through wall between cam bay and main cavity for legend 3 to fit, went for slower but more torque 4kg blue bird servos . Cant use battery over 35mm high. I assume other wood parts that came are intermediate fins? Didnt use any of that rubbish anyways. Running vector with airspeed, Multistar Elite 2205-2350kv built in ESC for more space. 7x3 Folding prop, frsky R9, TBS unify V2, blue beam airscrew, runcam eagle 2. Using it for my personal 1000mah 3s range challenge and is doing better than expected with efficiency. About 2.5 amps draw @ 11.4v to stay at 45kph.

Amount of carbon fibre reinforcing is assuring.

Anything under 35kph @ 1.4kg loaded and more than 20 degree pitch results in tip stall for myself.

Still tuning PIDs and gains on vector for now. Hopefully get some range going and even some Li-ion packs. Love this wing but not fond of its price.

Flys well in 25kph wind https://youtu.be/51tkmPx39dE?t=107


Sorry didnt crop video with garbage at thge start but tip stall around 2:07
Stallage! (3 min 39 sec)


Goes allot better with 4s 1400mah but tip stalling at 40kph (to be expected i guess).

Just my humble suggestion to combat the stalling: you might try moving the CG forward 5mm or so when flying it really heavily loaded. It may even need to go 10mm forward.

Im flying with a battery lighter and lower spec than recommended,. Only way for me to move it forward would be to start hacking out foam for the mere 10mm. To be honest it is a bit on the lite side but still flew both my skyhunter nano and skywalker mini at 30kph no probs with same gear. Only diff would be mobius cam vs legend 3 (hardly a diff imo). Probably more wing surface adding to the problem vs other small planes?

So 1.4kg is lighter than what the manual recommends? Holy sh*t. What does the manual recommend?

Manual states recommended parts "Battery:3S-4S 1300mAh-2200mAh"

Im 1.4kg on 1000mah 3s. No flying weight specified. Though flying with such a small lipo it does feel very floaty and lite. Could do with a bit more weight.

Lol, had skywalker mini over 2.2kg

Good looking wing.

Im looking for a wing in this size, sold my TBS Caipirinha 3S.

I know nothing about Skyzones products.
Are Skyzone better or different in any good ways than for example TBS?
Skyzones first flying wing? Is that good? CG and vobble is always tricky with wings.

It seems unstable in lower speeds, or are the wings in the videos not correctly built or balanced (CG/roll)?

Really small batteries. 4S 2200 the biggest that fits?

I saw another one asking how it it possible to balance without a GoPro.

Price is good/low. Too cheap wings equals lower quality...

What does THEER stand for?

Cronicash, buy a new scale!!! :-D My Mini SkyWalker weight is 324 grams. The Caipirinha was 650 g with GoPro 1 and is similar size as Theer.
