My aerobatic traing is going very well, I'm having all the fun I
thought it should provide. So far I haven't messed up a manouver but
I'm nagged by the thought: How can I tell if my loops are perfect
circles? At present I go to full power at the vertical phase and over
the top but then throttle back a lot as I go vertical again .My wings
are level when inverted. I'm pulling 3.5 G as I pull up and level out
again. I hit my wake every time but I wonder how much I should
throttle back on the descent phase. Should I just try to keep rpm
constant? Any ifeas BtB or Dudley or other aerobatic pilot?

Cheers
