Help with Dual Rates

[mcriley2]

I have an E-Flite P47D Razorback 1.2m and it's manual says to set the dual rates to 100% High and 70% Low.
However, the Spektrum receiver that came with the aircraft only allows a percentage rate that sets two numbers at the same time in the DR/Expo menu.
For example, if I move the DR to 100% it sets both numbers at the same time.
Lowering or raising the number does it to both at the same time.
There is no way to seemingly set 100% and 70%.
Also, there is a nice chart in the manual showing dual rates in mm's.
Not sure why one chart shows it in percentages and the other in mm's.
Also, no way I can find to set mm's in the Spektrum RX and TX.
Any help would be appreciated.

Excuse me guys for eavesdropping on your conversation, but I was very much interested in all the assistance you offered 'chipset35' on his dual rate subject. If you don't mind a couple of questions from me.

First - when setting up dual rates and travel, should travel be set first before setting up dual rares or does it really matter??? Second - can setting proper travel be done by changing control arm position and transmitter settings or just with the control arms ???

Thanks guys, I will let you know how this works out

It is the DX6e 6-Channel DSMX Transmitter.
I tried to set it in the Dual Rates menu

AS Viper said a better transmitter might help. I really don't know too much about DX6e. I just took a look at a picture of it on the Motion web site. Looks like it has pretty much the same on the front as my DX9, (meaning the front LCD display). In my opinion it's important, NOT to get into to big a hurry here Chip. Motion's tech support is really second to none. Problem is these programming functions can be pretty cryptic and confusing in the beginning. Once you learn them, you'll think god was I being an idiot, (This is how I felt, I'm not implying anyone is an idiot). Get someone from motion on the phone, and have them walk you thru it to make sure you get this right, very important! Yea I know hurry up and wait. If you do talk to them, discuss setting up some expo on those channels too. It can be linked to the same rate switch in a DX9, not sure about a DX6e. What expo does, is it allows you to set very precise control on your minimal control movements, and still allows you to keep the full throw if needed for any reason. This can make the plane much more manageable.

One last thing Chip, all your rates don't have to be the same on a specific setting. I like to have full or almost full on my elevator control at all times.

If it were me, I would make sure this radio will not do what you need it to do, prior to purchasing a new one. They're always things to spend more money on in this hobby, let me tell ya. Take some time, there are a lot of cool radios out there, I'm certain you will upgrade eventually. Spektrum's are kinda hard to beat, but they're are a lot of really cool radios.

Good Luck
Best Regards

Those two numbers are for either UP/DOWN on the elevator or ailerons OR left/right on the rudder. With more advanced Tx's, you can make the control surface go a different distance in one direction compared to the other if that's what you want. Did you try highlighting another line in the menu? Or did you flip the switch to see if it goes to the other set of numbers. Plane manuals give throws in mm because that's what you measure when you set rates. Tx give it to you in % because each transmitter may give a different throw at any given %. That's why they're different.
From the looks of some of your other threads, it would appear that you are progressing quite quickly in this hobby in terms of the kinds of planes you are acquiring. It might be time to get yourself a more advanced transmitter. That DX6e is very basic and limiting to what you can do.

You can only set percentage in the transmitter... any transmitter.

mm is measured at the trailing edge of the control surface and will change based on servo, linkage and the % set in the TX and/or other electronics.

As to getting the numbers to change as desired, you have t flip the switch to the position you will use, then change the value for that switch position.

Also you may have disabled the switch from being active in one or more positions...

I use the "Flight Mode" function for my dual (multiple...) rates since the different rates are normally associated with flap settings and other settings.

Which radio? are you trying to set it in "Travel" or in "Dual Rates"?

Agreed! "Rates and expo" should give you 2 sets of numbers, one for each switch position ........................ 3 rates if you have 3-position switches.
