Hummingbird sponsons

[Mark]

Does anyone that has run a Hummingbird with a 80 or 90 engine find that it carries the right sponson half to 1 inch of the water? Maybe this situation is a good time to test a small adjustable wing or diffuser tunnel on the right side. May be a little slower in a straight line but will be more stable.

Sounds like you need to check the sponson attack angle or the turn fin angle.

You are running to light.

Preston,

It only happens in a straight line, gets me thinking you may be right. Just a slight turn and it goes back down to just touching.

I'll put my money on the turn fin........... B)
