In reply #371, first line I said 'Indoor models'. I meant to say 'scale models'. It is probably equally true whichever way you read it but I do try to be correct.
As I have picked up my pen again I might as well add a couple more effects of left turns as I see it. In a small radius turn the outside wing is travelling faster than the inner wing and as lift increases as the square of the speed the right wing will be lifting a lot more than the inner wing, trying to bank the model to the left and tightening the turn even more. Then of course if the right wing does manage to lift it puts most of the weight of the model onto the inside wheel which adds wheel friction to the left turn effects. That chap in the cockpit must be saying: 'kick in some right' and let's get this crate in the air.
