RE: Learning Progress to more manuvers , planes?
There's a lot you can learn on a trainer. Are your loops held to end at the same altitude you began with? Can you do a 1/2 roll and hold level & inverted flight? Can you do a Split-S and an Immelman?
Up the control throws 25% and it will become much more sensitive.
I'd highly recommend a Big Stik 40 or similar shoulder wing model for a second plane.
