RE: SebArt Macchi Schnider Cup Racer
I think it should be kept as an Electric as the frontal structure is like you said fragile. I also think that it should be one or the other. It was not a Land plane so it should be a float plane, the wheels are a joke the attached picture shows that I have glassed those holes on the bottom of the floats where the wheels were, completely shut. It is and was a Float plane.
I did fly this plane, once, this plane with the wheels installed, off of water, it is a snake with those wheels installed. It almost did not take off and that only takeoff was scary to say the least.
I also think that the water rudder should be left off as well, it is a major drag inducing device that does not flip up when it should. If you ever watch a full scale float plane take off they retract the water rudder during take off as it is only used close to the dock, it is used for slow water taxiing only. When the plane lands the water rudder touches down first its instant drag causes the plane to smack down on its floats hard.
So in conclusion my wheel holes are glassed shut and my water rudder has been removed. I have 35 float planes and fly off of water everyday, yes my business dictates that I do so.
