AXI 4120/14 Big beastie..HELP HELP HELP.
I am electrifying a 12 foot wingspan sailplane as here in UK bungy launch isn't easy due to space as well as other benefits. Most items have been bought or selected for the job. The model motors AXI 4120/14 is bought.
I have scoured the webb for a suitable alloy cast motor MOUNT for this brushless job without success. The manufacturer markets a pressed steel version which I,m not keen on and will give me fitting probs. Hyperion (Hongkong) do one but just undersize to convert.
Any ideas Guys please? Does anybody know of a source??
Thanks...Derek.

Espirit Models has a dandy.

It's a backplate and a frontplate that are connected by four aluminum rods. The rods come in different lengths so the distance between the plates is just about infinitely adjustable. With the different length rods you can extend the motor so the prop will sit right where you want it.
The backplate mounts to your firewall and the front of the motor attaches to the back of the front plate so the motor itself sits inside the four aluminum rods. It is a great mount. A little on the pricey side but still a great mount.

AXI 4120/14 mount
Thanks Warden. Yes, I know about this mount and tks for your input. It's the best mount I've found so far. Being front mount and 2.5" square it means that too much of the existing eliptacle/round nose of the fuselage has to be discarded. Also, leaves too little room for the motors main power leads which has to pass the outer high revolving case of the motor if mounted this way round.

Yes, Derek, what about the radial mount that tim hooper pictures? That's about as tight a mount as you're going to be able to find. Sounds like you need standoffs... Just build a plywood box, or use four hardwood blocks and long screws. Another option is to use the right size PVC pipe coupler cut down to the right length and clamped between the mount and the firewall, using long screws.
Really, the radial mount is the best solution in tight cowls.
