Well, I’ve certainly run into an interesting issue…
I recently starting building a new drone (one of the flitetest gremlins) and am having an interesting issue with the receiver. Before I continue, here’s what I’m working with: f3 femto flight controller, frsky xm+ rx, and taranis qx7. All components and transmitter are brand new.
So, when I connect up to betaflight, it recognizes the drone and the gyros work and everything. However, when going to the configuration tab and changing the receiver to a serial receiver (documentation for the fc: http://www.yinyanmodel.com/upload/20161111/20161111094147991.pdf documentation for the rx: https://www.frsky-rc.com/wp-content/uploads/2017/07/Manual/Manual-XM%2B.pdf) and then to SBUS for receiver type and then saving and rebooting, it doesn’t save the receiver type and reverts it to spektrum1024. Additionally, (likely related) when going into the receiver tab, all of the bars read zero even despite changing the high and low ranges.
I’m pretty sure that the receiver isn’t broken as I am able to bind the qx7 to the receiver. Sidebar: when binding, the transmitter asks me if I want to bind channels 1-8 with or without telemetry or channels 9-16 with or without telemetry. None seem to make a difference, just wondering for when I get everything working.
I’ve double checked my soldering and everything seems to be in order.
Any help would be appreciated, I’m still getting into this kind of stuff and would really hate to have something like this hold me back from enjoying the hobby.
Thanks in advance.
Also, I can upload pics if that would be of any help.
