Help with Jetronic Brake valve
I am trying to sort out my Jetronic brake valve on a SM F15 for theweekend.
I have mixed the brake valve with the Elevator, so when I apply down elevator the Brake valve actuates. Is this correct
What I cant sort out, is to stop the brake valve operating whilst in flight!!!!!!!
I am sure there is a way of switching this mixing off, whilst in flight. But I cannot find anyway of doing this!!!!
I am using a JR PCM 9X mk2.. Could someone please help, as I am supposed to having a maiden flight with this, at the weekend!!
Many Thanks

Don't know about JR but with Futaba, just make the brake mix conditional on the retract switch position...

I fly JR 3810 ON AN F15 but I leave the mix on all the tim.As long as the mix only comes in at the extremities of stick movement there should be no air loss.

Put it on the snap roll switch. When you apply full down, you can unload the main wheels causing a lock up at worst, the least it can do is introduce instability.
I use the snap roll button on my SM F-15 with the Jetronic valve and it works great.

RE: Help with Jetronic Brake valve
Your elevator to brake mix can be turned on and off by a switch if you choose to program it this way. Just make your retract switch control the mix. Gear down: Mix on. Gear up: Mix off.
If you are using flight modes just skip this mix completely in the "flying" flight mode.
For the mix itself I recommend the brakes to come on as soon as you give down elevator. Then you will have little or no "tail lifting effect" from the elevator, even at high speeds.
