Thanks for the input. Looks like I will have to move the CG. I have also a a new OS 50SX. What do you think of this engine for it ? Is it heavy enough (only 13.76 OZ compared to 16.8)? I think it will be powerful enough (1.8HP). Or should I stick with the 72 Saito or 70 OS Four strokes ? How did you guys moved the CG ? Did you moved the battery and engine forward ?
Thanks
