DX7 Program Flap Deployment Speed?

Hi All

I'm building a BH Models Chipmunk using the 3 position flaps mix to drive 2 servos through a reversing Y from AUX1 of a AR7000.

Is there a way to program my DX7 to control the speed of the servos' movement? I'd like to slow the flaps' deployment to a more scale-like speed.

You'd need a "sequencer" to go between the RX and the Y to slow the servo operation.

There are few radios that have the capability to program the rate a servo will travel. JR 9303... Futaba 14 MZ... (Maybe the Futaba 12...)

Hyperion (and several other manufacturers, but Hyperion is the one I've used) make a gadget called a servo-slow, which can slow the servos right down. I've used one for precisely this application with a DX7 in a CMPro Cessna.

And not all of the servo delay devices work with Spektrum, so ASK first.....

Thanks for the warning, Mike.

Andrew (above) has had sucess with the Hyperion unit and Spektrum - so I think that's the one for me.
