components have been installed for CG reasons. You can easily move the turbine fore or aft several
inches to change the CG. For temporary installation use 2 small wood screws. Once you are satisfied
with the CG, permanently install the turbine using machine screws and blind nuts. Permanently install
the turbine before flying the first time. If you want to change the CG after the first flight, you can move
the turbine or the batteries, which ever you prefer.
