Do you have to buy the traxxas gps to run telemetry on my tqi for mph?
The mph is calculated by engine rpm and gearing and tire size not gps
p/n 6551 - Telemetry GPS module
pretty sure it also needs:
p/n 6550 - Telemetry expander module
Neither are available yet.
Alt-248 on the number pad = °
The gps module will be much more accurate!
