Thanks for the info on the transmitter Shaun, I already have a spektrum Dx6i so that's the only reason why I'm going to use it, most of the volume controls are easy enough to get to on a lot of my tanks so there should be no issue there, I may need a new radio in the near future though as the Dx6i only has a 10 model memory and I'm running out of space fast

Cheers, Lee.
