The problem isn't so much the time invested or stuff like that, it is the fact that there just isn't enough interest in them to do mass runs like that. I hate to say it but kits are hard to sell these days. RTR is the only thing people want. Unfortunately until there is enough demand or even requests for more kits I can't invest in the time to make one. However with this being said I have been pestering bossman to do another.... I will most likely take a poll eventually and see what people would like to see, my guess it will be a Sherman or KT.
Oh my email is [email protected], I'm very busy atm trying to catch up to things so please give me time to respond. Xmas is always super busy around here and even more so this year.

This looks really cool; as is tradition I have some technical questions!

It looks to me that both the suspension arms and suspension stops are held in with C-clip / retainer clip. Did you remove any of those? I have to guess that the suspension itself is similar to the Heng Long coil spring; honestly that would be my only disappointment with what I see here, makes for a toyish drive. Torsion bars optional one day maybe?

Bearings in the road wheels / idlers?

I'd love to see this in kit form when released
