Just noticed one more thing...

When doing the aileron and elevator to throttle mixing, the manual says that +% is pos throttle and -% is neg throttle.

The thing is when I set up +10% for all up, down, left, and right, one direction adds throttle but the other subtracts throttle.

I has to set it up with +10% and -10% in order for it to add throttle in both directions.

can anyone else confirm this.

Yes.

So far I love the radio but the manual is a disappointment. As long as it took Horizon to get the 9303 to the US market, you would think they could have got the book right.

The JR 9303

I've been finding little quirks with the programming. Nothing totally unfunctional, just things that are said in the manual or advertised, but that don't actually work that way.

Since this is my first good controller, I just want to make sure that some of these things are not just me.

You know the saying misery loves company and all.

Not that I'm miserable or anything. On the contrary, Its a great radio. Easy to use!

I noticed this as well and just figured the manual was incorrect. It is nice having these mixes built in instead of using a program mix as I did with my 8103.

I don't have that radio so maybe my opinion would not be so good, but have you tried to download the manual from the manufacturer web page?
In some cases they have the latest version... try !

Is that a mix specifically for cyclic to throttle, or are you using normal pmixes?

If you are using pmixes, then the behaviour you see is what I'd expect.

If you define right aileron as positive aileron, then left aileron would be negative. If the mix was the same sign on both sides then one direction is going to increase throttle, and the other side will decrease it.

actually downloaded the PDF manual and it is the same. If you look, the Heli manual has pictures of the airplane controller.

The mixes are cyclic specific mixes. But if you say that the programable mixes work that way, it must just be another error in the manual.

Conclusion?
The manual is wrong.
Do little changes to your radio and test how it works in order to understand the behaviour.
Thanks

I am led to believe that the errors in the manual are being addressed by Horizon.

Danny Snyder who runs the JR sub forum on the other Forum site is aware of the problem and has ( I believe ) passed it back to the technical writer for correction.

While I don't have a 9303, it sounds like the cyclic mixing software is identical to that of the 10X in programming and function.

I couldn't figure out why my non-governed heli was bogging so badly in flips even though I was using the built-in throttle to cyclic mixing. When I actually checked the operation I found it was backwards from what the manual said. My mistake for assuming that it would be correct!

So yeah, the 9303 manual is a real let down. The radio itself is fantastic. But I guess I have been spoiled by years of using the PCM10 series of radios with their excellent (and correct) manuals.

The biggest problem I have with the 9303 manual isn't so much the errors, but rather what is left out. Many of the unique features of the radio get very little explanation of their functions. In some cases, it explains how to activate a feature. But doesn't explain why you'd want to use it, or the advantages it offers.

I agree with the above statement that the manual should be a lot better considering how long it took to get the radio to the US market.

And the downloadable version is the same as the printed one. No updates yet.

I actually tried the cyclic mixes this Sunday an they work really nice.

One thing I like is that on 100% throttle, the mixes have no effect, thus they work within your throttle curves and don't bind/overdrive your servos.

Yes, that is a nice touch. Too bad the manual doesn't mention it!
