RE: I need some help!!!!!!!!!!!!!!!!!!!!!!!!!!
I can feel your pain guy's.
your airboat is easier to tune out of the water due to the motor being under load by the plane propeller, so when you tune it on land and it runs great on the whole power band it will run fine on the water.
the regular Nitro boats however thats a different story, if you tune it on the table so it runs great, it won't run in the water.
Tune them (HSN) so they run fat (rich) on land, very often if not most of the times you will need to bleep the throttle to clear the engine so it won't load up and stall.
clear it just before launching in the water and they should run fine.
