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?


Dudley's the guy, but the only really reliable way I know of to tell
until you become experienced enough to know by feel is to get an

outside
observer, or, better yet, a tripod mounted recording of them.
Into the wind helps a lot BTW, but "L" shaped or "granny" loops are
pretty much standard at this stage of your game!


OK but it's not practical for me to have a ground camera. Should rpm
be constant at all stages? What do you use in your Citabria? Could I
try counting through verticals to give me an indication? With a 3.5 G
entry I'm puliing about 0.5 G at the top is that going to give me a
near circular loop?


Mine's stil not flying! Aaaargh! More delays now. I'm going on a fairly
rusty memory now, so take it al with a grain of salt, but just get a
friend to take a quick snip of you from a distance if you can. The other
option is a good ground observer, preferably with a viewing glass for
the loops ( something clear with a circle on it so he can hold it up
against your figure to compare)
Max poser as soon as it will take it all the way up


Love that typo!!!!! Max poser indeed!!!!!!!!!!!!!!!

CHEERS!
