Hi, I for one have Telemetry in my electric car, I have the DX3 with the display on the receiver itself, it is rather hard to look at the display during racing anyway. I have already hit the barrier as it is, thankfully no damage, but that proves the point that you can't really take your eyes off your car to look at the readouts. I also have the handheld setup too, this is a lot easier of course. All it gives you is an idea of how the car is going, how is this different to someone trying a spur gear for example to get a certain result? Anyway, once you have reached the optimuim setting you don't use the telemetry much after that. The telemetry I think really comes into it's own if you are able to drive the exact line every time, 'cause you've only got to go " off line " by a small amount and the lap is going to be different. Unless you can make changes on the go then what harm is there?

Cheers
Steve
