I went the "Kmart" route on a Shrike. 40 I have. I installed a 46pro with a 9/7 apc which turns 17000 rpms and goes about 120mph. Not too shabby for a cheapie. I am not fond of GMS mainly because I no nothing about them. It is my guess though that the engine with a 9ish apc prop on a Clipped DD will be an impressive handful.
