[QUOTE=AdamChicago;16021525]Well I glued the skywalker motor to the EPO mount last night using Gorilla glue, woke up this morning to find the motor totally locked up.

I haven't started my SW build yet, but I expected that a plywood-type firewall with blind nuts would be glued to the foam, and that an X-mount type motor mount would screw to plywood. No direct gluing of the motor needed at all. What am I missing (?)

Bump Minklein's question about a single wheel. I'm very likely to try that unless someone has found it be a bad idea.

Minklein -- PM sent to correspond about ideas on single wheel. Will post to SW forum when I have results, good or bad, but it'll be awhile.

Bummer about the motor. Obviously, you have no choice except to dig the motor out. Then you want to apply a new mount, keeping the same angle. Use a mount that you can attach first, then attach the motor to it. Yes, you might be able to salvage the motor.

Regarding the sensors, as I understant it they are infra-red sensors that detect the difference in temperature between the air and the sky, and use that to determine the horizon. So clearly, as others have said, they have to have a clear line of sight to the horizon.

That sounds fine. If you are using blind nuts for the purpose of screwing in the motor mount, perhaps lube up some screws heavily and insert them so no glue gets in the threads. The problem a lot of poeple have is that the x-motor mount is too big for the plywood disk, so they have to figure out how to deal with that.

Good suggestion about how to keep the blind nuts clean, Jim -- Thanks. Sounds like the size problem is manageable. I've not read all of the forum threads (yet), but that size-of-the-motor-mount issue sounds one of the more minor considerations. Thanks............R

Easy. Sand the rear face of the motor mount area till it is flat. What you're doing is to get rid of the "inset" firewall. Then trace the outline on some 1/8 5 ply plywood. The set the X-mount on the firewall and locate the mounting holes for blind nuts. Drill and mount the blind nuts, glue firewall to the foam, and enjoy a great mount.

In reality, I trim off about 3/4 inch of the motor mmount area to move the motor forward some then make the plywood firewall to the shape as shown.

You may want to range check with the flasher on, I built a flasher circuit with a few transistors and a cap and it sent out an RF spike every time the cap discharged.

I found out because my friend came and told me something was wrong with the TV turns out every time it discharged the cap the picture on the TV would go to static!

good luck...

I haven't seen anyone do this. The main issue, I think, is that the plane tends to be tail heavy, so if you do use a wheel, find a lightweight one.

How about making a skid out of steel wire?

The single wheel issue is not a problem, it depends on what you want to do:

-if you want to protect your plane's belly from the roughness of Tarmac or dirt track then this is a good Idea.

-if you want to protect the belly from landing on grass, loose gravel or sand, then the wheel serves no purpose and you would be better off taping the belly with duck tape or packaging tape..

-if you want to take off and land on wheels, then it is a no no , you will not be able to ROG on one wheel

if you decide to install the wheel then do it right under the CofG spot

Someone should sell these. I did something similar and it took forever and didn't look half as nice as yours, Crist.
