RE: Flying Characteristics: Viper Q-500 Pulling up in Turn Number 1:
about 90% of all the planes I see at the races have left wing tip weight.
I like Bill's suggestion of rolling inverted and checking the cg that way. If you get the cg so the plane flys level both upright and inverted , the plane won't drift toward the canapy when you roll up for the turn at #1
You should read Dave Normans speed secrets at the top of this forum. He has a lot of great tips for trimming there!!
