Using a Newton propeller 60 x 38 on our UK reg Hawk. Works well with 3200 rpm max in straight level flight.
Have an issue with a progressive roll to the left with ailerons, flaps and control stick set to build specs. Adjusting rudder trim has no discernible effect. Going to try the aileron differential remedy commencing with 1 degree difference. Anyone else
tried this and to what effect. Thanks?

So I got a chance to mess around in the hanger, this is what I've found.
Ailerons are completely in line with the flaps. There appears to be no 2 degree (or any degree) of upward angle to them. I still need to grab a straight edge and make sure the flaps are right, and then adjust the ailerons to the appropriate "up" angle relative
to the flaps. I'm thinking this one at least part of the reason why it starts getting laterally unstable at higher speeds. I'm not sure, of course, but it seems?
The propeller appears to be a Tennesse props 62x42, which is, as expected, far too much propeller for the jab 2200. I need to do some playing with the engine and do some maintenance items before I'm comfortable taking her out of sight of the airport. Hopefully
soon though.
I'm thinking 60x38 for the propeller is the norm for the Hawk and jab 2200 combo, Can anyone tell me what they are using on an H? I know Mr Coates has put together quite a few, I wasn't sure what was used with good success,
Thank you all again for your help and insight!
Tom
