Dual Rate on JR 9303 Radio
When I go to the DR/Expo menu on the radio it gives me three sets of values for each channel (0, 1, and 2) Each one has a DR setting that I can make and an Expo setting that I can make for Elevator, Aileron, and rudder. My question is how do these settings work with the switches?

I have a switch on the top left (F.Mode)that has a N, 1, and 2 on it which I assume correlates to the (0, 1, and 2) in the settings. I also have elev DR, aile DR, and Rudd DR switches which pretty obviously are related to the DR settings.

So for the question, Does the separate DR switch for the elevator, aileron, and rudder take on a different DR value as preset in the three settings (0, 1, and 2) that are entered into the radios programming when the F Mode switch is moved from N to 1 and 2? I assume the DR switch is set for 100% on 0 and whatever the value is programmed in the radio when switched to 1??

see page H15 & 16 of your manual.

you have a choice of either flipping a bunch of switches to get
everything in D/R OR you use 'Auto' mode where the D/R are set
by changing flight modes.

Thanks z11355, I read those pages and still don't understand the switches. I went to the very right of the setup screen and under the word auto, you can set the norm, st-1 and st-2 to pos0, pos1, and pos2. When I set this, does it disable the three switches specific to DR and make the F.Mode in control of DR/Exp? If I set these to INH, does this then turn control over to the three separate switches? Also, are DR and Exp both controlled by the one position of the switch, either the F.Mode or separate DR switches or are they somehow separated, ie, Exp on F.Mode and DR on the three DR switches?

I don't have a 9303 and the manual is pretty vague but it'd be simple to plug in a servo and test it if the display screen doesn't give this info when you flip the switches.

I don't quite see the point of "Auto D/R" since you give each flight mode it's own set of D/R and Expo values anyways. As I see it, all "Auto D/R" does is swap D/R and Expo values in the selected flight modes to create confusion.

I don't have any servo's right now. I sold them because they were not up to a helicopters rigor and haven't bought new ones yet. What I was able to do is bring an airplane up on the sim and bring it in front of me close. I can then try different switch settings and watch the result on the airplane controls. Somewhat the same as a servo in a way. It seems that I lost the change with the three separate switches when I set the auto mode up. It appears from the manual that the reason for auto DR is to make the three controls, aileron, elevator, and rutter be controlled from one switch rather than three switches if I understand it myself...

I'm still confused as to whether DR and Exp operate together on a switch setting or separately with different switches. Any insight?

Usually I think Expo is always either on or off in the various flight modes and not controlled by a seperate switch. But looking at the 9303 manual, it seems you can incorperate Expo with D/R. Pretty neat as you can use either or both in different combinations and "switch" between them. 2 rates and/or expos per flight mode.

This is the only radio in it's class that I'd consider trading my Stylus for, and would probably do it now that I'm back into planks too.

Would you say that when you go into the DR/Exp setup on the radio and you can set DR at what ever percentage and leave Exp to linear, you would then have only DR on that switch setting. You could leave DR on its default and set the Exp to what ever percent, you would then have only Exp for that switch setting. If you set both of them at what ever percentage, you would then have both for that switch position?

It appears that the three switch settings on F.Mode control these settings when you set the three options under Auto on the far right.

What I can't seem to figure out at this point is what DR value is assigned to the three DR switches on the radio. Also is there a DR and Exp value assigned to each switch, or is it only a DR value. I'm not sure which of the three values in the setup is assigned to the DR switches and how you assign the switch to which setup value. Make sense?

So far, I'm impressed with the radio, but the manual is sort of lacking for a novice like me that has never had any experience with computer radios, or RC radios of any kind.

Thanks for the help. Sorry if my questions seem so basic.

Yes, to all those questions. The D/R and Expo are controlled by the D/R switches and have all the flexability mentioned unless "Auto D/R" is used, then I believe only the F-Mode switch controls them which probably frees up the D/R switches for other functions you may want to assign to them.

Without "Auto D/R", you should get 2 switchable Rates/Expos per each of the 3 flight modes. (6 Rates/Expos total, maybe 8 if you include Throttle-Hold).

*Remember, I'm just assuming all this from my interpretation of the manual.*

Side note you don't need to plug servos or a sim into the 9303 to see what the controls are doing. Hit list and go to the main menu. Scroll to Monitor, click... this shows a screen where you can see the readout of the signal the radio is feeding out to each channel post mix / D/R / Expo.

I'm wrong no matter what I do, so I might as well have fun doing it!

Thanks Shaltac. I purchased the Ray's Athorative DVD series and he goes through the monitor function. The DVD series in my opinion has a few holes in it, and is a bit on the unprofessional side, ie, lots of mistakes that he then uses text across the screen to correct rather than reshooting, but has great information in it on the 9303 radio which is why I bought it. Great setup for the Raptor 50 also. I don't have one of those, but think the tips he gives are good for any heli.

It's really nice to see how the mixes work on the different channels. To check out the DR/EXP settings I find it shows best on an airplane. I bring one of the models up on the Reflex sim, I don't remember which but it's a large plane. I taxi it over to my feet and put the radio in the different modes and watch the reaction of the elevators and ailerons on the airplane. It's actually surprising how much different they react with a change in DR/EXP on the radio. You are right though, it's the best way to see the changes.

Appreciate the feedback
