Tip for Rx. padding. Try using some of that foam in a can that you use for filling holes around your house. But first rap the Rx. in plastic rap, because until the foam dries it's wet.

A friend of mine gave me this idea after I ran out of any other usable padding and we wanted to fly. I wasn't real sure about this idea at first, but it was an old trainer plane put back together a few times, so I tried it.

After two great flights and landings, I lost the use of the elevator (servo failure we think) the plane took a hard hit, noise first into the ground. Had to dig the engine out of the dirt.
The Rx. was just fine. I've lost one other Rx to a hard hit before that was rapped in foam rubber.

You could just peel away the foam with your hands. It also kept that part of the fuse it was mounted in still in tack. When the rest of the plane was just about dust.
It was light and took the shock will.

I'm thinking of trying it for other use's as will. Like around the gas tank to keep vibration down and tank foaming. Don't know if it'll work or what fuel may do to this stuff, but I may give it test try.

Another tip: If you ever need nylon bolts for anything like holding landing gear on with. Don't buy them from your hobby shop. Get toilet seat bolts from Wal-Mart or hardware store. They work great and are less than half the price. You may have cut them in half but they work great!

Another Tip:
For a very light weight and strong wood filler try using Elmer's glue and Baby Powder mixed together till it feels like auto body filler, works really great!

Just keep adding the baby powder till you get the thickness you want. Apply just like body filler and sand down flat.
