Questions & Answers
Real questions from real customers. Why not ask your own?
Hi, will this esc work with the axial scx24 transmitter or do I need any dsmr/dsm2 transmiter for it to work?
Alan / 18th April 2021

I don't think it'll work with the SCX24 transmitter. You'd need a proper DSMR transmitter - eg say a DX5

Ben @ Wheelspin Models
Will the smart technology be compatible with older Spektrum DX5c transmitter
Kevin / 29th September 2020

It will still work, but you won't get telemetry on your handset
