The trimming quandry
A truly competitive design for todays maneuvers is basically zero zero zero
The reason being that a competitive electric FAI bird flies at almost constan speeds and the only real effect which requires compromise -is the twisting action of the propeller.
Huge fuselages which provide more or less constant lift in almost any attitude (transitional lift) and tiny highly tapered wings are all part of getting a design which will do 6 snaps -in a row - with little or no apparant track deviation.
I looked over Andrew Jesky's latest models (he lives here now ) and it looks to me like he has it figured very well - for the latest style flying
Compromised angles may help in some setups but personally I found they were not my cup of tea .

In playing with a lot of foam models for the past few years - I changed my mind as to what constituted a really good highly aerobatic setup.
The wings are now not much more than guidance vanes ( well maybe that's pushing it) )
The big ol fat fuselage ain't there for drag - it really accomplishs a lot of the lift required.
Time marches on
