RE: Strumtiger
I sprung for the metal wheels from WECHOE and the smaller idler from BYA for mine. Still working on the camo.
The RTR is nice but you'll want to repaint it so it doesn't look like everyone else's. The Imperial Model kit is challenging and fun to build with a couple different gun weight's to pick from in the kit plus the bolt on armor plate for the lower front hull to add if you want.
