Well, so far, I've counter-rotated the props for now till I can find out if
they do in real life.
I've got the thing flying reasonably and the stall normalised at about 80-85
dirty / 100ish clean.
I've already experienced what you mention with the incidence at the tips (the
twist of the wing). I'm trying to work out if I can make an average between
the two that wont make Yasim throw the toys out of the pram.
I've also managed to reduce the 'dragster' runway performance a bit but it
needs more work to match up things like rate-of-climb etc to the real
