Is there a process to convert beam mount 1.4 4S planes to current electric tech. I'm not sure of the size elect. that it would require to properly power a 10# plane, is there a way to mount it in place of my favorite YS140's. The firewall is not suited for a direct type mount. I dont know if the proper E-motor can fit between the beams enough to line up.

I use old wet power mounts ll the time. I'm presently flying a Bristol M1a with an Aveox 36/38/3 using an aluminum mount for an OS 15. A little grinding and a hose clamp did the job. You can also make a "clam-shell" mount out of brass or aluminum. I use some left over flashing. If the spacing is too wide you might need to make up a plywood mounting plate that spans the motor mounts and mount your e-motor to it with triangle stock (for alignment) and either a hose clamp or brass strips.

If you need more details let me know.

OOps, if you're planning on using an out-runner it gets more complicated. I'd have to think about that. Off the top of my head, I'd think you could use one of the Great Planes or Hyperion universal mounts and if you can't bolt it to the firewall, then use "L" brackets to attach to the motor mounts.

Here are a couple of options to explore:</p>

For "old" plane, I guess you will like to save $$ w/o purchasing fancy stuffs. Here is my cheap way. Ugly but works.</p>

Luke,
nice conversion! Looks elegant, not ugly. It's an outrunner version of what I described for inrunners. Nice job.

If you all keep it up I will run out of reasons to avoid the transformation to electric. I think it looks great. The old exhaust exit makes the charge connections accessiable and keeps the batteries cool.

Great idea and pictures Luke! Thanks for sharing.

Ihave an untouched SL1A kits in the loft I have often thought about building for electric. Biggest problem I can see is the undercarriage. The plane is designed for retracts not fixed gear and I would need to substancially increase the length of the undercarriage legs to account for the big diameter props you need for an electric motor.
It ticks all the rest of the boxes. Big Fuse. Plug in Wings and tail. Generous nose area for cooling. Definitely has potential.

it was an expensive kit and I am going to need to do something with it.

I like the wau the motoer is mounted. Quite clever.
