just got a new radiolink RC8X. out of the box it seems to only operate in forward reverse? i see posts about calibrating to the esc but I am using it with a Holybro_Tekko32_F4_Metal_4in1_65A_ESC speed controller. it is a blHeli32 ESC i have set it to forward/reverse mode. i dont know of a way to set calibration on it. isnt there a way to jsut get forward and reverse movement without having to go through a calibration? I turned on the brake to give some reverse function but this is less than ideal.

First of all, this part of the forum is for issues with this forum, there is an electronics section you can ask this.

But the ESC looks like auto sensing. So be sure the trim and subtrim are centered and the range to 100%

It is a pretty advanced ESC: DShot ESCs — Copter documentation (ardupilot.org)

Hi Y'all,
I purchased this transmitter just about a month ago, and the tension wheel spring snapped, unfortunately. Can you guys point me in the right direction where to get a replacement - thank you...

Read my post above yours. This is not the place to ask electronics questions.
Beside that, I would go to the shop or contact the manufacturer for warranty.

My mistake as to the forum. As far as the question, in fact I did contact the manufacturer, researched the web, hance the question in the forums, regardless thanks for your input.
