Robin nice airboat i have one question about it how do you turn i was guessing one engine throttles up more than the other one.

and is that a 28 mm flatside Mikuni on that chopper?

the 2 stroke sound in the second vis is of the bike recording it

the carb was of a honda cd200 and i read on the net that it had a 28mm carb

the airboat stears with rudders on the back it would refuse to turn at full bore so it was scraped ime making a new one now as a school project
