I keep hearing of hangar rash.
What is it and how can it be avoided?

I have just picked up a second hand airframe thats way to advanced for my flying skill. But it was a bargain. So I intend to tidy up all the nigly bits, then keep it as a display model. I going to need a big area to display this one

I have heard that the covering film looses its oil from being in the warm in a house. Is there anyway of avaoiding this?

Thanks Lee
