Default RE: Comp ARF Valiant

Unfortunately I live in the NE and the weather has not been favorable and our club field is closed from Jan 1 to March 31. I did get get 2 days of nice weather before the field closed. I also flew it in several days of windy weather were any real trimming was difficult.
First impressions: the plane flies differently than my other pattern planes setup with similar settings. The counterbalances on the stab and aileron strongly effect the feel of the plane. Much less expo is required for a normal feel. I will have to check but I I think I have 10 to 15% expo instead of the normal 40%. The rudder on the other hand was very sensitive. I had to crank up the expo. Otherwise even a little rudder input was really obvious. Moving the CG did effect knife edge as Bryan states. Really shows how critcal CG can be. I am not sure if the vertical will be perfect with no mix to KE. May require a little down thrust, or increase in wing incidence (but it is not set to be adjustable.) Still need more time and tweeking to know for sure. Vertical is pretty close with knife edge going straight. I think it may need a little right thrust as it tends to veer a bit to the left at the top of the vertical. Perhaps the electric version requires a bit more than the glow version. Mine has an adverse roll with rudder and is mixed with 6% rt and 7.5% left. Plane lands like a dream Unfortunately that is about as much as I can give right now. I will have to wait till spring or move to a warmer climate to give more impressions
