I like the way my GP Shoestring flies (powered by Irvine .72). Bit it does have a tendency to spiral when rolling in vertical climbs and dives.
I am using a Futaba FF6 Tx and have the ailerons setup as flaperons - which gives me the capability of putting in some aileron differential.
At the moment I have -50% down aileron dialled-in. Does anyone out there have any experience with the Shoestring settings, and the reason I seem to need this much ?
