Well, suppose the unit arrives and does NOT work properly. Rather than send it back, why not just strip out the guts and do a wee bit of Frankenstienian surgery to replace the non working stuff? Yeah, it would cost some money and time but hey, it's a hobby right? It's what I feel would be preferable to paying for shipping (again) and possibly getting another bad unit. Besides, it would still be cheaper than a Tamiya, and I'd be able to learn more about systems before I shell out mucho duckets for the Tamiya.

I think I'll just accept what I get and go from there. But thanks for your info, it's been very helpful!
