Default RE: engine power-down
i would definitely NOT put a 13" prop on any 1.20 sized engines.. Use a 15x6 16x8 and you'llbe happy I run a 16x8 or 17x6 on my OS ax120, and 16x8 on my webra 120 speed, and a 16x8 on my saito 120



Dont bother paying attention to the "practical RPM range" try to stay in the 9-11k range for your 1.20 2 stroke and you'll be fine



Edit: Just noticed i hit 2000
