Hey all. New guy here, and dad of a noob actually. Hoping to find some guidance as I've been searching for answers and hit road blocks so here I am. Anyways...

New build:

So we got The Boy a Traxxas TRX4 Sport build-it-yourself kit. He's at the point where he's mating his ESC with reciever/transmitter but has hit a stumbling block. The ESC is a SPEKTRUM 60a brushless 2100KV sensored motor & ESC combo. His transmitter/reciever is a TACTIC TTX300. The point he's stuck at is the ESC calibration. Its almost as it the TACTIC won't vibe with the SPECTRUM. He's trying to set his throttle position but the ESC isn't responding. The ESC seems to run through a start-up mode, LED flashes red then green, then as he tries to calibrate the TACTIC, he gets crickets...

Some searches through RC forums isn't revealing too much, but Ive seen a couple snippits where people have said they won't mate up, but the posts are a couple years old. Hoping the tech has evolved since. Can anyone confirm? Anyone have experience with this combo?

Thanks.

radio receiver are bound? if yes check throttle trim is at zero .. now try calibrating esc/

Yup trim at zero. It's like when the esc boots up, it won't link up with the transmitter after.

Sometiimes you need to swap the servo reverse function on the throttle channel.
