PMix help
I have a 7C radio and I have not programmed in many pmix's and wonder if someone would help me with this. I would like to add a Throttle to elevator mix so I can have better flight trim through my throttle range. I am flying an Extreme Flight 48" Extra 300 and at 60-70% I am at pretty level flight at neutral flight. Add power and it climbs and reduce throttle and it is diving. I am thinking that I need to trim for WOT and add a mix that adds down elevator at low throttle.
Thanks
Thanks

RE: PMix help
Sounds as if you've got up thrust in the motor mounting.
That would be highly unusual for an Extreme-Flight airframe but none the less
that is something you should check out .
I've flown a number of examples of that type which were simply dead on so something is amiss.
Has the airplane been damaged or did you buy it from someone else ?
This is a Futaba site so this message won't last long as I'm not Futaba.
They can give you the how to's for mixes but that isn't your problem nor is it the correct solution IMO.

RE: PMix help
You could do a Pmix with Throttle as the Master and Elevator as Slave and then set your rates to a small amount, adjustments to the amount of rates will probably take a couple times to get this correct, but it isn't too hard.
First go into an empty Pmix, press the cursor button to enter the mix, press the Down key twice. You will INH flashing, cursor over, press the cursor button and change this to Off. Press the down button once, and set Master as CH3, press Down once more and set the Slave as CH2. At the very bottom you will see the switch selection, if you would like this mix to be active only occasionally, then set this to the switch of your preference. If you would like this to be active continually, then set the switch to Null ().
Pressing the down arrow button once more, you will be on the Rate page, I would set these rates fairly low to begin with, once you fly, you will be able to decide if you need to add more or less elevator per the throttle action.
