HL plastic in my hands- thanks Crius!

No problem, Pat. Let us know what you find when you open that turret, and if you need parts just holler.

Hey Gary- is the HennTec idler sprung, or locked in at whatever position is needed?

And BTW, did you notice that the HL road wheel placement is not symmetric left to right? Which is actually correct... the cross-hull torsion rods are staggered of course, and one side's wheels are 8" further forward each. I posted drawings of this on my old Yahoo site, and I like to think that these got out into the wild and were used by today's manufacturers. Here they are again... note that the offset even makes each track's approach angle different with respect to ground.

Henntec is locked in one position.
