Hi!
Imcub you would be better of putting a APC 11x6 on your .45 engine! A 10x6 Master at 14500 rpm is just putting out a lot of noice and does not produce as much "thrust" as a APC 11x6 would and at lower rpm. 14500rpm is way to much rpm for a trainer aircraft if you want to fly in a relaxed maner!
A TT.46 will not swing a APC 10,5x6 at anything near 17000rpm but a 9x6 APC might reach that rpm.

SuperpimpN have you adjusted the needles on your engine ? (I know that the Evolution does have an idiot safe needle system but you certainly must have the possibility to adjust the carb needles do you...??
