Re: Limit throttle with a pot

if you want to understand how the offset works, download the Er9x manual and go to page 33. There is a good explanation.

OpenTx works the same in this case..

Re: FrskyRX_USB dongle

Yep that works too. Just solder it to the pad that connects to the center pin of the u.FL connector. Be careful not to short it to ground.

Re: FrskyRX_USB dongle

I would say no, they dont. I believe they could even get damaged. You could use a normal receiver antenna (not a dipole antenna) and roll it in a circle (not too tight), and probably hot glue it to the PCB. Another idea is to shorten the antenna. Cut the antenna's coaxial cable shorter, and then exp...

Re: Limit throttle with a pot

Mike, I see one of his mixes uses the source "MAX", that means he is using openTX, so he might not have the sticky throttle safety switch, or it is done in a different way.

Re: 9xr pro , YAW input when throttle up ?!

Are you sure you don't have any mix on the yaw channel that shouldn't be there?
Also go to Radio Setup / DiagAna menu. The first four lines are the 4 sticks. Check if the yaw stick's values also change when you move the throttle stick..

Re: Continued-Infrared module for JR compatible TX, including 9x

You need my RF module soft power switch circuit. :) It will only power the module ON if a signal is being sent to it by the radio ;) I know this is just a workaround to the problem, but I think it would work.. And you would be able to turn the module ON or OFF via the firmware :D Only for Ersky9x th...

Yes, the IC is used so that inversion can be enabled/disabled by software. Yes, of course.. I understand.. Just wanted to know if it was really needed for the 9XT. It probably would, if I wanted to use the module in different radios, but as it will be installed internally, it is not needed, accordi...

Re: 9Xtreme and Multiprotocol Module With STM chip

The problem is that I couldn't easily find the IC at a good price. As I said the module will be installed inside the radio, so it will use COM2 which according to you is fine without the inverter. COM1 is used by the module bay telemetry. If really needed, I could use a transistor instead of that IC...

Mike, I am looking at building a Multiprotocol with a STM32 chip. The module uses a "SN74LVC2G00DCTR DUAL INPUT POSITIVE-NAND GATE". I have been told that this chip is needed because of the Taranis radio. I am planning to install this module as internal in my 9XT radio, and use COM2 for th...

Re: Taranis gimbals in 9xr-pro, no stick readings, and transmitter randomly shuts down.

Check your connections to the sticks. You might have a short circuit on one or more connections. Some chinese that work for flysky seem to be color blind, so don't trust the colors of the wires. Get your multimeter out and measure before you comnect things. First with the radio OFF and all wires dis...
