Not sure if there is any interest on this subject,but have started a scratch build of a 1/16th unlimited hydro.It is a Gary Finlay drawing which I believe have been around awhile.
I am a fixed wing and heli flyer,but have an interest in boats as well.Over the years have built two boats but never a hydro.so now is the time.The pics show a few hours work so far.
Hope to run brushless and li.po batteries.Open to any comments on the boat and power system.
