? on trim tab length
 

Hi Ya'll,I'm runnin a os.21 powered NITRO VEE,Speedmaster surface drive,w\4" rudder,prather 250\2 blade, this thing gets airborne at every blip of throttle,(not so bad a thing under controlled impulses to do so):D,this thing really gits but had no tabs installed at the maiden voyage this past weekend,(fast idle speed got me to 25mph) and was really unstable,My ? is would longer 2"x4" tabs improve HIGH SPEED stability(45mph +),I know it effects the overall COG, what would the effects on stability be if extended beyond the prop??Does splitting the tab (2 separate adj. tabs,on 1 side) help\have any more benefits than just a single hinge point tab? this thing really is a beast that needs to be collared but not leashed.......what do think guys n (gals)...
