Hi Dominic, here are the links to the conversion gear I was talking about earlier. The basic principle is that you solder (or join with connectors if it's easier) the 2.4GHz conversion module into a transmitter of a different frequency, such as 40MHz, and it then transmits on the 2.4GHz frequency. There are three simple connections that need to be made. Positive, negative and signal/PPM.

The positive and negative connections can be easily made as there are many points inside a transmitter on the circuit boards and wires where you can connect to. The signal/PPM wire can be a bit trickier to find, but if the donor transmitter is, for example, a 6-channel Futaba model, they are usually pretty straightforward.

The conversion, or 'hack', module: http://www.giantshark.co.uk/product/...ication-system

You'd also need a compatible receiver;

4-channel: http://www.giantshark.co.uk/product/...ceiver-v8r4-ii
8-channel: http://www.giantshark.co.uk/product/...annel-receiver

And then you'd need a donor transmitter. This is the Futaba Field Force 6 transmitter. I've converted two of these (and a Skysport 6) to run on 2.4GHz and they do a great job: http://www.ebay.co.uk/itm/RC-Futaba-...item2c98680bb0

Unfortunately that's a bit of a higher price than I got mine for a while back, so if you add on the cost of the conversion kit and receiver, it would bring the total cost to around £100 (give or take with P&P). On the whole, that's still a good price for a 6-channel programmable transmitter with six different model memories (allowing specific parameters to be calibrated for up to six different robots). When converted, you can also 'bind' this transmitter with multiple receivers so you can use one transmitter to control several different robots (not all at once!) much like the DX6i. However the added work required to convert the transmitter may mean that for a beginner such as yourself, getting a 2.4GHz radio such as the DX6i may be more tempting as it's all ready to go. Just wanted to offer up an alternative though as the failsafe and bind processes on FrSky gear is ridiculously simple and proven in the arena.

Where in Scotland are you based? The Kinematic Events beetleweight shows will be at a few Hungry Horse pubs in Scotland in early August, and Robots Live are probably going to be at the Glasgow Comic-Con at the end of September if you're looking to get along and watch (or maybe compete in ) some robot fights.
