Thanks for the info it give me a starting point. ELMOD looks like abit much for me right now to replace the stock tx/rx as the only other good radio I got is my DX7 for my helicopters. I might look at it again later on just not now. I think Ill focus on the scale detail and general smoothing out the tank at the moment, and maybe when I pick up another one possibly a IR system. This is also a NON- S&S tank.
