I question the original statement about 'bad habits' - is this due to the particular airframe or just the style of plane? If the OP crashed a scale aerobat because of generic coupling issues, why are we recommending more of the same type?

Extras and Yaks are a big jump up from an Escapade. It's not that I don't want to see you in a fun aerobatic plane, I just don't want to see you posting about more headaches and crashed planes.

I would think something like the Venus, Reactor, U-Can-Do, and other capable yet user friendly planes would be a better step up.
