I keep posting about my hobby so not much more to tell. And funny stories around it, well there's almost always something dodgy looking happening and I never intend it really XD
Your plane story sounds like what happened to eldest's rc helicopter when he let his then 5yo brother have a go. It went up and up and up and eldest said DON'T FLY IT INTO THE TREE and youngest just let go of the up stick and down it came in a hurry.
Good luck with the repairs :)
Things that fly tend to come back to ground fairly quickly when they cease to fly. Something called gravity I think. I didn't factor that in I guess, neither did your youngest son.
