Analysis

The acft collided with an overhanging tree branch during a river takeoff. The plt was trying to negotiate a bend in the river while on the 'step' for takeoff. The plt said he had very limited experience in the model acft and it got light on the floats and skipped in the turn quicker than he was 'used to' in other acft.
