the frsky is a good way to go but quality can be an issue .. the AE radios are easier to get and are cheaper ..you can also get them from you LHS or find a used one on EBAY or ask around at the local RC club someone usually has one from an RTR car also the frsky is not designed for ground, it works but the recievers are not pin up
If you have questions feel free to ask. I check this most evenings.
