Lack of interchangeability of module limits its versatility. But who needs interchangeability at this price. Just buy it as another extra transmitter. I will end up posessing 3 transmitters; iMAX, Turnigy V1, Turnigy V2. After all, cheap is not cheap if you sum up money I spent for 3 transmitters. I could not resist buying additional transmitters because it is so cheap. They will replace my old transmitters which do not have electronic trims.

After reading many posts on several boards, this is what worked for me on a total of 5 of the $9.00 Turnigy receivers: Attach the "batt" and "bind" cables in reverse position, as listed on the receiver. Turn on the receiver and note the flashing red light through side panel of receiver. Take the transmitter at least 6 feet away from the receiver and while holding in the "bind" button (on back of case), turn power on. Red light on receiver should turn from flashing to solid red.
The only other problem that I experienced (other than the poor connection of the batteries within the holder) was with 8 Nicd batteries (Sanyo 1.2V, 600 mAh) installed in the stock holder, there was no way that the battery cover would fit on the back of the trans. I simply replaced them with a 3 cell lipo 2500 mAh transmitter battery; fit perfectly in the case and even the Futaba-like plug mated perfectly with the jack inside (charged to storage value only- 3.8V/cell)
One other curious item was when testing servo channels, channels 5, 6, 7, and 8 would not function at all until I enabled them individually within the programming. Not a small feat considering that this is my first "fully" programmable unit and no manual was supplied.
Also hope that the weather "Down Under" permits flight/range checks soon.Side
However, if they'd used a UFL connection on the end of the antenna wire rather than simply soldering it to the circuit-board, other plug-in modules could have been used simply by drilling a matching hole in the back of them and connecting the internal antenna to the UFL that is almost always found on their circuit-boards.
