Re: X-Lite Pro

Ahhhh! So probably one can't mix PWM and analog gimbals on one radio (i.e. left stick analog, and right stick PWM)... And that must be the reason for the trouble I see...

Hi Mike,

That link leads to a 'file not found' (and also for the regular X-Lite).

Re: X-Lite Pro

Oh, my bad! Surely it's there! Thanks a lot! :) BTW, do you know whether X-Lite Pro supports both 5V and 3.3V Hall effect sensors on gimbals? The radio on my desk has one gimbal with 3.3v sensors, and the other gimbal with 5v sensors. The one with 3.3v works fine, and the other one jumps between 0 a...

Re: X-Lite Pro

Hi, Is there a way to get an Xlite-S version of the ErSkyTx ? At least a beta... :) All links seem to be gone... I'm investigating a misbehaving stick on the radio and I'd like to see raw ADC values. I think OpenTX doesn't show these, and there was such an option in ErSkyTx (if I remember correctly)...

Re: Radiomaster TX16S - need help updating OpenTX

Answering to my own question. There's an article at Radiomaster's web site that explains my situation exactly: https://radiomasterrc.freshdesk.com/support/solutions/articles/64000267226 According to the article, the issue arises because the MCU is read-protected. How it got to this state remains a m...

Radiomaster TX16S - need help updating OpenTX

Something went wrong while trying to update OpenTX from 2.3.11 to 2.3.14 on a TX16S. Now the radio does not power on - neither normally, nor in bootloader. When connected to a PC, the radio is detected as an 'STM32 BOOTLOADER', so there hopefully is a way to recover without a need for hardware inter...

Re: Q X7 does not power on

When connected via USB, the power output line gets ~4.5v all the time (but the input is 0v, so this clearly does not ...

Hi All, I got my hands on a Q X7 someone previously tried to repair. The radio did not power on and showed no signs of life whatsoever (also when connected via USB). I spotted a missing diode in the USB power circuit. I put the diode back and the radio is now detected as an 'STM32 Bootloader' in Dev...

The solution Customize attempted to suggest is to have a setting (perhaps somewhere in the Hardware menu) that reassigns the MCU pins. His idea is to swap the Internal and External ports. This way, the Internal will get all the bells and whistles, while External will become limited to PWM (CPPM, DSM...
