tks Britbrat, I did the mod you suggested on post 6 adding a round leading edge to the eng pylon ond a triangle shaped one aprox 5/8" to the trailing one. How far fwd and aft did you extend ?
Eng I am using is a Satio .72, very happy so far. Must say the batteries are still in the front compartment.
Due time someone else finished the kit and I had to remove step by step about 7 ounces of weight he had attached to the nose section. It´s flying much better now but knife edge flight as I said is still in the works. ( Just started with that)
If I may ask, how much throw do you have set available for your rudder?
Did it show marked pitch dawn tendencies when doing knife edges?
