That's interesting BB, I got just the opposite advice from the English bloke who has built two of them and filmed his flights on YouTube.



"Oh dear, I forgot to tell you.
You have to fly it!!
If you try to induce the turn on aileron, the model will bank, carry on flying straight on and start to slip, just like the full size.
You initiate the turn with rudder then feed in opposite aileron to keep the turn flat, takes a little skill that's all.
Forget mixing rudder with aileron, you'll kill it.
Forget differential and messing with bellcranks, just fly it."



I must say that it looks a grand sight in the air and I have received many compliments from clubmates about it. Shame I didn't build it myself!
