I am getting a U Can Do 46 and was wondering what the best engine setup would be. It recommends a 70 for the top of the four stroke line and I was thinking of maybe a 91 for only two ounces more. I will be using it to learn 3d. I would like to know if anyone is running either of these two setups? if so what props would I need for these two engines? BTW both of the engines are O.S.
Any suggestions would be greatly appreciated
