Hi all

need some advice got the FG cowling for the T180, i am fitting a electric motor,
if i fit the motor direct to firewall i am 2 1/4" short of prop drive

the option are

cut cowling back 2", for protrusion

add a block of wood til prop drive is out of cowl

make a long metal bracket and mount the motor

advice please on best solution

Move the motor forward to align with the front of the cowl. with the light weight of a typical electric motor you need to get the weight as far forward as possible.

thanks john


would you use a block of pine to extended or make a aluminium bracket, using 2 - 3mm standard flat ali be ok ?

time to get some card board out and make a mock up

Plywood is the answer. A block of pine will split. Just make a box out of 1/4 ply and epoxy together and to the firewall. 21/4" is a lot to pack out or make standoffs. Drill some holes through the joints and epoxy some thin dowels though the joints for strength.

thanks bob

just gave a light bulb moment

i have a metal lathe, Stand off why the hell did i not think of that, DOH!

using part wood part ali stand-offs will do the trick and give me a bit more nose weight as well

thanks bob you are a star

Richard, just make a plywood box like Bob says, keep it simple rather than useing part wood and part ali stand offs.

thanks paul

box is being been made up using a mates cnc router. i ditch the stand off as the impractical after i mocked it out with cardboard
