Hey guys. While running through the components that I am using in my brushless TT-02, I thought it would be worthwhile covering the radio set I have.
I am using the E-Tronix budget transmitter and receiver. This may sound like a cheap option, and you would be right. This is currently the cheapest 2.4ghz radio gear set that we do at Wheelspin.
However don’t be fooled into thinking it is cheap rubbish. This transmitter can more than hold its own with more expensive competitors.
One thing I immediately noticed was that the quality and feel of it are not dissimilar from many of the handsets of some of the 3s lipo cars. It does not have a cheap feel to it at all. The range also seems excellent - I have run my car a very good distance away and it behaved perfectly well.
Ok so let’s cover the basics - included in the box are the transmitter, receiver, and binding plug. It uses 8 AA batteries, giving it 12v of power and has a low voltage warning when it reaches 9v (green LED will flash). There are two channels available with a third channel on the receiver which can be used to power a motor fan. You can adjust throttle and steering trim and dual rate manually.
Binding
Binding is the process whereby you match the transmitter to the receiver. To do this, use your bind plug which will plug into ch3 on the receiver (rx has 3 channels, tx has two). Then follow the simple process in the manual to bind them together.
Failsafe
The E-Tronix receiver has a built-in failsafe. This feature means that if for any reason, the signal to the receiver is lost during operation, the car will instantly return to a pre-set throttle position. This needs to be set after the initial binding is completed.
To set your failsafe throttle position simply power up the car and follow the instructions in the manual. Set the failsafe throttle position to neutral so that the car will simply roll to a stop if signal is lost. This can be tested by giving the car a little throttle on a stand so the wheels spin, then turning off the transmitter to simulate loss of signal. If done correctly, the car should lose all throttle input and just stop.
Assuming this all works ok on the bench, then you are all binded and the failsafe has been set - you are ready to drive!
My Review
I am genuinely really impressed with this radio set - I would happily put this one on pretty much any RC car or boat with 2 channels. The only thing it is missing is a built in gyro receiver which is included on some more expensive sets.
Great feel, loads of features and adjustability, failsafe protection, good range, long battery life, and very cheap…what's not to like?
I give it 9/10.
