This is an old thread, but I took my SV27N out to the lake recently
Problem is it doesn't want to turn right. It looks like prop is coming out of the water and boat decelerates. I'm not sure what's wrong as I took the boat apart (down to empty hull) in the winter to properly clean it, so all my previous settings are gone.
I tried to bend right tab upwards to no vail. Setting strut to positive and negative also doesn't help.
I'd appreciate any hints what to do to make boat turn right properly.
On the plus side - I did a sketch of radio box and printed in on my 3D printer - it's sturdy, will outlast the original one
I'll share it on thingiverse soon.
