I'm puttng together a ohio models pro yak 47. Going to use a Satio 82A. Does anyone know about how far to mount the motor on the wooden rails. I don't want to have to keep moving it back and forth to get it right for balance. As said I'm using a Satio 82A. Another comment I have is these instuctions are really poor. I have built all kind on ARFS Kits and so on. Man these intructions suck.

Some help if anyone has the answer.

Thanks
