I have a transmitter with Open TX.   When I buy a BNF quad is there and advantage (disadvantage) in choosing one brand of reveiver over another?  Or is there no diffrence assuming you can bind to it.  If there is a difference, how do you choose? Thanks in advance.

Which transmitter do you have? If it is one with a multiprotocol module then I would still use FrSky receivers over other brands, even with some of the firmware headaches you have with them. Either that or 3rd party FrSky compatible receivers.

Thanks, I have the Radiomaster TX 16s transmitter.

I believe that's a multiprotocol so just make sure to get a decent receiver and you should be fine. I'm a fan of FlySky receivers but FrSky are great as well.... Also FrSky is muhch smaller and more appropriate for drones

So RM has multiple protocol. The receiver world is your oyster. If you don't care for telemetry, then Flysky do make some small receiver and just a tad less than Frsky. Like the Flit14+. If you want telemetry, Frsky is the way to go. The Frsky R-XSR is probably your best bet.

You can use Spektrum, but they are quite pricey.

Here is a list of all the protocol available to you.

Or get the crossfire TX module for the back and go crossfire. imho it would be the much better long term option.

Whatever you choose, just don't go down Frsky R9 route. It is a mess.

It might save SnowLeopardFPV a few grey hairs later on....lol

Go Crossfire if you plan to go 900mhz.

I originally bought a Frsky Taranis transmitter. A couple months later, I realized crossfire was worth it and converted. The only drones I still have on frsky is my Mobula6; I even converted my Tinyhawks.

With crossfire, signal issues are a thing of the past. It was always a concern before.

If I had it to do over again, I would get crossfire from the start and save a few bucks vs starting with Frsky and paying more to upgrade later.
