Unfortunately, the controls are isomorphic - meaning they're directly linked to me - so no one else can use it. Troublesome thing to do, but if I don't, people steal it all the time and wreck havoc on my own plans, and there's absolutely no fun in that." And it would take a long time to alter the controls for general use, really. Otherwise he would have gladly let the child try his hand at it.
