Default Program flow rate Sullivan Skywriter/DX8

Does anyone have a guide for programming the flow rate of a Sullivan Skywriter smoke pump with a Spektrum DX8?

My pump is currently on/off only set to the gear switch. It's smoking like crazy but dumping out way too fast!

I can't figure out how to reduce the flow rate on the DX8.

Please help!

You have to slave the channel your pump is on to the throttle. For instance on the 10x only one of the pre-programmed mixes has a throttle curve tied into being able to combine with another channel. I tie gear to throttle for this.

I'm not sure on the DX8 if it has that specfic mix but that is what you need to find.....where you can change points along a curve mixed with throttle. Then your pump you will find never needs to run more than half its max speed to get plenty of smoke.

I just figured out how do that with my new 9503 using a TME, but I think they may set-up very similar.

I slaved Aux4 to throttle on Mix3 and reassigned the switch to a more convenient one.
P0: +72 on top,+100 on the bottom.
P1: -125 and +125.
Offset: zero
Thro Stk: 11

I adjusted the "on" EPA to +15%, and left the "off" EP at -100.

Hope this helps.

I can't figure out how to do this on the DX8. I'm sure this is correct--but how?

Maybe the 8 has a totally different menu, but my DX7 shares similar programming features with the 9503. I do know that with the Spektrum/JRs Mix 1 & 2 are "stickied" to certain surfaces, ie rudder/ail etc.

It must be different. I can't find a way to do anything with slowing down the flow rate.

So I go into the gear menu and lower the travel's high value end point to lessen the flow?

I just installed a sullivan smoke time for the first time, can someone tell me how to program my Futaba 12Z to regulate the amount of smoke as you are doing with the Spectrum or JR radio?

They all program the same way, in that you make a mix were throttle is the master and another channel is the slave i usually use the gear channel. then after that set up the travel curve so it runs on hi at wot and ramps down to next to nothing at idle.
