Thanks,


It's an old Sig Extra 300 Arf, with a FP 2.4 engine (43cc)

Simple solution is to purchased a reversed servo. I don't fly Futaba but I do JR and both manufactures sell this type of servo. Check it out before you invest in a servo reverser.

Ive had both problems, dual servos for elevators moving in different directions... solved with a mix at the AR 7200.
The other is different brands of servos conected to a Y (for ailerons) moving in the same direction... Cant win in this hobby

Hitec servos are very easy to reverse. You can buy 2, pop one open and reverse the 2 wires on the pot and the 2 wires on the motor. However I had the same problem with my Futaba 8UAP, and like the other guy said went on the Futaba web sight under the frequent asked questions for my radio and followed the steps for "jury rigging" the ailavater function. I don't know why they had to make it so fricken hard.

Servos reverse'ers are against my religion... you can't trust them. Do it with the radio or mechanically.

Yes, you can slave one elevator to another channel. That is the perfered method. don't use a Y harness if possible. The servos are not exactly the same in speed and throw., they may fight eachother to a degree. If you must use a ''y'' harness, you can get a servo reverser , that will make both servos travel the same direction from most any hobby shop or try Tower or Horizon.

The MSA10 matchbox is a good option in this case... Lot of ways to do it...

Good Luck,

Gray, that is the single reason I moved to the 9C. I did however setup my old 7C in my buddys 50cc Yak with a smart fly EQ2 and it worked
perfect.

Joe, it all depends on the plane setup, if you are using dual elevator servos you will usually end up with a geometry issue, with horns opposing
each other. Still flying competitions?? I am probably going to fly some intermediate this year.
I use the 9-C but one friend bought the 7 thinking if they looked the same?? That's when we found out about the need for a Y. The 9-C defaults to Ch.8 if you want two elevator servos and have the correct RX.
I didn't know they had fixed that problem in the new 2.4 7Ch. Looks like the OP got it figured!
