IWM
I'd say that is a pretty darn solid build! I particularly like the interior - is the kit 'designed' as a convertable, or did you just decide to build it that way?
I do see one problem - and I have to chuckle because I've only done the same thing about a dozen times - it looks like you've got your tracks on in opposite directions. They should 'point' up at the sprocket.
But hey, like I said, I've only done that a dozen or so times, so don't beat yourself up about it.
Nice work.
