oh...you had me excited. Back to my brake design I guess.

To all who think you need a high-end radio for external brakes. The Jr XR and XS FM radios (and airtronics maybe, not sure) have a feature for mixing the third channel with either the throttle or the steering and they run between 150 to 200 new, so you don't need a real high-end radio to really use it to maximum advantage

Minimum requirment is that you have at least a 2 channel radio (one channel throttle, one channel steering). Thats it. You can use the stock t/emaxx radio or any other radio on the market.
