Guys,
I have just finished my new yak 54. Its from CHmodel in china. Ive also got a Katana and the Pitts S12 from them, best quality ARF kits Ive ever had. Anyhow here's my latest model, a 90" Yak 54 with a 3mm 53cc up front.
Now it didnt come with any instructions so the CG is ????? I balanced it with the C.G on the wing joiner, seemed reasonable to me. Where should a yak 54 balance? Ive had 2 test flights and it seemed pretty close, inverted required only a tiny amount of down elevator however flat spins were not existant at all (confusing) even with 45 degree throws.
I'll take some chord measurements tomorrow and the wing joiner position but where do you think it should balance as a % of chord (most info Ive found gives distance measurements not % measurements that I can directly translate).
My favourite part of the whole model is the aluminium cowl vents, a very cool feature indeed.
