Fly Wheel Suggestions

Ahh, correct me if i’m wrong, but Isn’t 7:1 (84:12) x 3:1 (36:12) 21:1?

So if your using a 21:1 thats probably a little more reasonable :p. In that case I would say that its definitely a case of excess friction. Go through your gearbox and check everything!

Cameron makes some really good points:

Thank you for your help, I will go through and try everything you suggested!
