What is a good ul1 rudder upgrade?

[dana]

Since I put a grim 40/57 on there it's a rocket, but hard to control. Real squirrelly on the straights. I'm thinking there's ALOT more lift on that prop and a longer rudder would help. Does the speedmaster bolt right onto the stock mounting bracket? Anyone? I don't want to make new holes anywhere... Thanks

Rudder should be fine using that prop. IMO longer rudder will create more drag. Try adjusting the strut and turn fin. Rough water conditions will also make the UL-1 unstable.

ive been running in glass. its weird, it wont stay straight. when running the 40/52 it was never a problem. im wondering if a straight turn fin would help, but i cant find any.
