Hi all im in the process of converting a Dunlap-27 tunnel that i built back in 2003 from nitro to b/l power . As i no longer have the building instructions as where to set the prop shaft elevation for proper height . Would i be correct at assuming that a elevation of 1/8'' - 1/2'' above sponson bottoms would be a good place to start ? Regards Andris Golts.
Prop shaft elevation for Dunlap-27 ?

Personally I would start significantly lower than that. Center of shaft even with the board with neutral thrust to start and go up/down from there. +/- thrust as needed. CG will be a factor as well.
