I have the Evolution RPM sensor on every RCEXL based iginition (DLE, Saito, VVRC) I own. Simply plug the RPM lead from ignition into the EVOA107, or newer EVOA113, then insert into the RPM port of the TM1000 - done. Great tool for establishing throttle curves, prop testing and tuning.
Good telemetry thread on RCG
