I've been flying with the DM8 module and got tired of dealing with the large connector on the back side. See my mods to route the antenna coax and connector internal to the transmitter. Something else I need to make is one of those transmitter balancers. Without the long 72MHz antenna, the C.G. of the transmitter is a lot lower and the neck strap attach point ends up too high.
