Clark Model announced today that they intend to develop a 1/16 scale Mk IV Male, something I've wanting to see for years. Not sure yet if it will be kit &/or RTR tank, I have Takom FT-17 which I'm currently converting to RC so this is a plus.
If you don't know Clark, they are a major supplier of RC tank & truck electronics: www.clark-model.com
For those interested in seeing this project come to fruition within the coming year, feel free to visit Clark's Facebook page & lobby for the kit. Clark Liang, the owner is very responsive to the market input & responds quickly to what he sees on his Facebook page: https://www.facebook.com/CLARK-MODEL-313209919787/
