My spectrum dx9 has drift which is caused by the pots. I have heard that spectrum is noted for this. What do you say? If I decide to replace it what are you members using?

Recalibrate the sticks with the CAL routine.

Speaking for myself, the Airtronics radios that I fly have great pots but so do a lot of other systems. If the pots are drifting recalibrate.

I quite happy with my Futaba equipment and my last three radios have all been Futaba. It's been maybe 10-12 years since I made the switch.

While I wouldn't say they're the "top of the line", Spektrum does produce good radios at the DX8 level and up. I have a DX9 and my pots have never drifted. They zero every time and and I get full travel at the ends on the monitor page. I got it last October right when they came out and I have a ton of flight time on it since I can pretty much fly year round. Great radio.

I have a Spektrum Dx8, DX18 and previously owned 2 ea DX6i

I also own a JR 9303 and an 11X

I cannot see any difference in quality between any of the >6 channel radios. I would consider them (>6ch) all to be top quality.

I have never seen any Pot drift in the 8 years that I have been flying. It sounds like the radio needs to be sent in.

Are you using digital servos? It makes a difference.

Digital servos have absolutely no effect on pot drift inside the TX.

Which Radio??
There are a lot of choices out there but you might want to look at the NEW JR line..
Both the XG14 and the XG11MV are excellent radios...definetly worth your time to look..
I have been flying JR equipment since 1991 and have had no problems with sny of the several models I used..
Add outstanding service and you have a win win...
Good luck with your search.

Not the top of the heap, but my Futaba 8FG has been perfect for two years. Zero issues. Currently set up with 9 helicopters.

Radios are kind of a hard thing to figure. SBUS or not to SBUS is the question in addition to DSM2, DMSX, DMSS, FASST, etc...Then there are the compatible accessories required to make your selected system function as advertized .

When I picked up the RC hobby again after many years, I bought an 8FGA only because I used to have Futaba. Post purchase, I was able to upgrade the software to make it an 8FG Super 14 channel and Customer Service sent me a plastic cover for the ratcheted throttle making it an 8FGH Super. (all of this for free). I have used it to fly 4 fixed wing and 3 Helos. It is the only radio I take to the field.

Wonder how to take the ratchet out of the 8FG throttle without destructive modification, add the plastic piece. (but I digress).

I've seen allot of radios and in general terms, the more money you spend, the nicer the units are. Materials, spring rate quality, bearings, setup pages to infinity, interface, battery life, etc all increase with price. If you can, pick one up, hold it, and see if you like the grips and stick position. Youtube is enough to get your mouth watering.

I have discovered is that there are many reasons that drive you to a brand. Once you have arrived at a brand, you more or less need to be committed. With DSM2, DMSX, DMSS, FASST, FASSTest, FHSS out there, there are potential forward and backward compatibility issues across the brands.

I was pleasantly surprised that my new Align Helos with 3GX worked with my SBUS capability. Made the setup easy (only 1 wire between the gyro and receiver) and the SBUS receivers are super small and less than $60 bucks. (3GX also accepts up to two Spectrum or JR receivers straight to it). My fixed wings use standard multi-channel receivers and standard digital servos. It would require addressable (programmable) servos or add additional adapters to plug standard servos into to go SBUS (a total retool).

Bottom line, comfort, expandability, and price point is what I would use to determine my next radio. Recommend making an evaluation of the accessory equipment you require, then pick an 8 channel or above Futaba, JR or new gen Spektrum (these are the nicest radios I've seen, it's not a coincidence these units dominate this discussion).

Poopfong: You can modify the futaba throttle ratchet by putting a piece of fuel tubing over the metal clip inside the transmitter. Make sure you have the tension correct on the screw for your desired liking and it works perfectly. However I like the idea of Futaba sending out a free piece to do this as well. Just an FYI as I've done this to several radios and it always work very well.

It makes a difference if you are seeing centering issues. The digital servos do not center as well.. Thus you might think the radio is wack and it is really the servos. There dispute that!

Back to the original question. History: For many years transmitters used servo pots in a can. They lasted a very long time. Then some cost savers decided to use the ubiquitous surface mount "angular sensors" designed for consumer products - Murata, Alps, Bourns. These were grotesquely overrated since the spec. was wearing through 20% of the carbon or some such. This leaves the dust on the surface and makes them useless for our applications - noisy. SO the original blue Murata "encoders" used by Futaba would last about 100 hours of actual flying. These were replaced by the Futaba white Murata pots TEN YEARS AGO. These are supposed to last 10 times as long - maybe 1000 hours of actual flying which exceeds the life of the transmitter - problem fixed. Curiously, the Robbe Futaba transmitters used the black Alps pots and not the blue Murata.

I have a JR XG14 with two Clarostat pots in a can (JR servo pots) AND two Alps pots. I am waiting to see how long they last.

And of course the 18MZ has new super sealed pots. Reportedly the most expensive pots ever put in a transmitter.

All pots wear out eventually. Hall effect sensors are crap since they have huge hysteresis that has to be programmed out - to hide centering problems.

There is one valid reason to use the new surface mount pots - it makes it easy to put a ball bearing on that end of the gimbal.

Pots are not all sealed. Dust and dirt can easily get into your transmitter. You can sometimes blow out the dust with a can of air. Keep your TX in a case.

Can you elaborate on the drift?

How did you determine drift is coming from radio?

Does it happen to ALL your models? same channel(s)?

Does it still happen after recalibrating?

What you heard, was the DX9 mentioned or older models?

What servos are you using?

I'm more interested in troubleshooting given I have same radio and have yet to experience drift in any of my models with digital or analog servos. Otherwise, this is just another one of those threads.

As mentioned, radio relative environment plays a role in product longevity.
