To be honest I havn't flown the Yak as much as I would like cause it runs 4s 3200 batteries. As I charge on site from a booster pack these take alot of power to charge so I tend to use the charger for other aircraft. This meant I would fly the Yak once then wouldn't fly it again for a few days so never really got to grips with it. I now have 3 batteries for it so can fly more and explore the capabilities.With my rearward CG it seems to harrier ok. The problem I had last time I flew it was I came in very high alpha and dragged the tail through long grass then did a go around and flew a couple of circuits. When I landed I noticed most of the left elevator was missing.Because the front of the elevator is forward of the hingepoint at the outside tip for balance, it goes down when the elevator goes up. Grass then got caught in the gap between the elevator and stab and ripped the whole thing off when I throttled up to go around. She flew perfectly on 1 elevator so I didn't notice till I landed.
I got an RC Factory Yak 55 foamy to practice with and it really helped with my 3d manoevres. Am tryin rolling harriers now. Some are fairly good but most are horrible. My best 3d practice aircraft is my TechOne Venus. Really lightweight and can fly any manoevre cleanly. Recently bought an Edge 540 in 32inch span but it uses 4s power and is so quick it dissappears at such a small wingspan but good fun.
Yeah shame we don't live closer. Would like to be able to swap models etc
