RadioMaster-R81 8CH R1MINI FrSky D8 Compatible Nano Receiver with Sbus

Easy to solder, paired quick ,range is what it should be

I recently bought this because it was a cheap frsky reciever and my old reciever broke. I bound it with my tx16s and was greatly dissapointed. It only goes about 10 feet and then I lose connection. I also have no connection if my radio is too close. I want my money back!!

Just received a replacement after the first one was DOA. No problems this time. Bound right up and works great. Tried it on a model with a eagle a3 stabilizer which takes an sbus and works perfectly. The range on this rx is just amazing. I am going to try and replace some of my older rxs with this one where i can. Great product from Radiomaster.

With the new firmware updates that FrSky has made. My old 3rd party controllers ceased binding. Thankfully, this worked like a charm. Easy to solder install, just make sure to find a good schematic so you know which pad is witch. Also, keep in mind that this will require D8 protocols.

very good range . i havent had a failsafe yet and i go out as far as my 1200mw vtx can go . it nice to be able to replace the antennas if they get damaged. its VERY small and fits on all my 3" and 2.5" quads . ive purchased 5 far and they all still work well up to 2 yrs later thru many crashes and getting wet and dirty . i cant think of 5 of anything ive had with that kind of track record. highly recommended .... now if someone could just point me to a 1000-1600mw 20x20 vtx that works this well.

Product is very easy to bind, but that’s about the only good thing about it, put it in a drone and flew it around my yard out of 4 flights 2 of them I lost connection within 100ft of the drone no obstacles between, luckily I was close to the ground so the landing weren’t so harsh but I will be switching it out to elrs. Not worth the risk of crashing

Binds very easy better then the rsxr I highly recommend it problem free so far -my rsxr was giving problems binding or asking for updates so frustrating the radio master receiver binds on first try awesome you got my next sale for sure

well, binding with my Radiomaster tx16s MKII im getting very bad connection and that is only 6 feet away. transmitter keeps saying connection critical.. connection critical then it will lose signal etc.. yes i did the frequency fine tune and that didnt do anything. total waste of time and money.
