Hello Paul,
This is the equipment I use. I got the list from Will Moore who had the first Electric powered Shark.
Orbit 20-18 motor,
Shultze F2B electronic speed control
Thunder Power 2700maH 5 cell, 25C, G6 Pro-Lite battery (their latest version)
APC 13" 6.5"pitch Pusher prop
Hubin F-9 timer with remote start
Safety plug, to keep battery disconnected while in ship.
When your model is almost ready to ship, they will ask for payment via international bank transfer.
I do not understand your question regarding bellcrank overhang.
I enjoy flying my Electric Shark very much.
