I found that if I tried to run on the front step only the boat porpoised terribly and would flip if I kept in the throttle too long. This was accomplished by moving the CG, jet thrust vectoring alone will not be enough. I was constrained by the semi-scale design, you will not be.

A float plane rides on the front step by using wing lift to stabilize the attitude, which we do not have. Getting a balance between CG and thrust vector to keep the boat on the front step only will be a challenge. Float designs vary so yours may be more - or less - forgiving than mine.

The upside is that running on both the front step and the transom is still a huge reduction in wetted area and drag over a solid bottom, or especially compared to a flatty. While it would be great to be able to run on the front step alone, it is probably not too practical especially for a prototype. I suspect that you will have a fine running EDF boat with the CG behind the step.

Did you see the videos? I will try to post more.
