Rio EP brushless conversion HELP??????? plz

[aminoacid]

Some pics. Center of gravity is about 7.5 inches from transom. 25 inches from back to front. pushing batteries back as far as I can get them gives me a 7.75 cg , close.
I like the turn fin ideas, those would be fine tuning I assume. Notice proximity of rudders to prop, literally will hit the prop if the rudder turns far enough. I had the prop pushed inwards towards the transom when videos were taken. Could the prop wash be hitting the rudders too much contributing to the roll? I will pull it out maybe 1/8 inch or a hair more? What u think?


I have a spartan stock, it screams an a bit unstable wobbly at full speed. This rio is more exciting to me and more fun because we try things out and build, creativity is wonderful.
