Mount the Electric motor on the Seniorita

Hello all,

I am now at the stage of trying to figure out how the electric engin should be installed in my old SIG seniorita. I assume the built-in down thrust is supposed to be kept and I also assume that the right thrust mentionned in the instructions is the same as for glow engins - right?

Last question would be to distance from the firewall to the propeller, I assume it should go just outside the balsa nose cone - right?

If someone have a nice idea about how build a engin mount it would be greatly appreciated, now Im just planning to pile a bunch of sheet ply (with epoxy) and glue it to the fire wall- feels a little primitive but can't figure out another way to do it.

Regards Steff

We like the standoffs. Easy, easy to adjust, cheap, blind nuts in
the firewall. On big motors the double thing make them steadier.
We get them from HeadsupRC.

Hardware stores carry some sizes but they are $$$$!

The back of the prop should be at least 1/8" from the fuselage.

Or you can build a box:
