Im trying to convert a Nitro Planes Mosquito to electric. However, getting the motor to come out of the cowl in the exact center is proving to be hard to do. Does anyone make a "floating" motor mount? Using Axi 2826/10 for motors. Any help will be greatly appreciated. Thanks, Ken

I just used aluminum tube stand-offs to mount my 2820/10's on my Bronco and Twin Star.

I'm sure someone makes what your looking for, try calling "LA Johnson" at Hobby Lobby, he helped me allot in the beginning.

I used aluminium stand-offs on my CMPro Mosquito and flew it on Turnigy 4260 500s. Getting it centred was reasonably easy using a template to ge the holes in the right place.

You could also use PVC pipe with 2 end caps for motor mounts. The cap that will be mounted onto the fire wall drill 4 holes for your bolts.assembly the mount unglued ,attach the motor to it , stick it through the cowl. When you have the motor shaft in the center you could mark the end cap that`s touching the fire wall from the other side of the fire wall. or put a screw in the end cap from the back side to hold it in place. To do this you would have a small hole grill in the center of the fire wall where you think the motor mount would rest. Remove cowl and remove end cap with motor attached to it . Now you have a open end tube use a marker to mark out the 4 hole for your bolts. You can also put lightning holes in the side of the PVC tube.

I wonder...

Could you take an old prop spinner.. Big enough so edges of the spinner touch the inner circle of the cowl. Drill a hole in the tip of the spinner (if it doesn't already have one). Then put the spinner into the cowl (pointy end towards the firewall) Make shere the base of the spinner if parallel with the face of the cowl...

Once the spinner hits the down, the point will automatically be center.

Viola! Mark it, or what ever.. it should be REALLY close.

Oh...!

If you've got the depth to do it, make a 2 stage motor mount. Then you can move the motor around on the second stage all you want until it's where you want. Mark the mount holes and drill.

On your Mossy, you could make the first stage tall enough so the motor sits on the second stage (no stand-offs). Temporarily make it tall enough so the prop shaft extends out the cowl. Drill a big enough hole on the intermediate mount so you can slide the the motor around.

Then, draw a circle the size of your cowl opening on a piece of light cardboard (cereal box works well). Drill the center the size of you prop shaft. ( You could possibly use your intended prop spinner base as well.) Put it on the motor, and use it to center the motor in the opening. Once positioned, remove cardboard, mark and drill mount holes.

If the first attempt is off, no sweat, chuck the intermediate mount, and try again. That way the firewall won't end up like swiss cheese.

Thanks for all the help guys!!! I'm sure one of the ideas will work!! Again, THANKS!

VMSGUY....

I think you've got your wheel pants on backwards, unless that airplane is a "pusher-canard"???

It is indeed a pusher-canard. Long-EZ.
