The GP Trainer 40 is not what most would consider a primary trainer.
It has a fully symmetrical airfoil, very little dihedral, and is more like a "stick" than a trainer.

Skeeter,
If the 11x6 is too fast for the way you like to fly, and you want to stay with MA, here are two options
12x4 http://www3.omnimodels.com/cgi-bin/w...I=MASQ1359&P=7
12x5 http://www3.omnimodels.com/cgi-bin/w...I=MASQ1251&P=7

As far as speed, the calculated number at an arbitrary 10,000 rpm is
4 pitch 37.9 mph
5 pitch 47.3 mph
6 pitch 56.8 mph
