AC boats are one of the best out there.
The lazers i have seen was with 231s and 260s in them, they run wett to begine with. Its a boat that turns left as well as it does right. All the lazers i have seen were set up with the M&D drive as well.
Im sure a .90 would work, you need to get with Andy on what the CG Should be for a nitro engine.
