Skywriter programming with JR 9503

Ok So I have searched the forums and I would like some clarification.

I have my pump on the gear switch. I want to have curve for a little coming out at low throttle to good smoke at 50% or more throttle.

Can someone please give me a picture of your mixing exactly as displayed on your 9503 if you have yours setup similar to the way I am asking. OR write it out clearly.

Thanks.

I am flying my skywritter in a 50cc race edge. Using a DX7 for now .
So I have no graph for you,,i did mine by ear, dry during set up, find the mix programing you use ,and adjust the motor .To the stick position ,by ear,,,By listening to the pump run with no oil ,DRY.,(Set it up with a empty tank) no motor sound at low stick and gently increase the mix setting for the stick position,, I can tell you this,, just start out small ,thru out the stick range.
If you set the mix for full puming your just wastimg money and smoke oil for nothing.
Because the sky writtter will empty a tank in less than a minute,you ll just be puming raw money thur you cans .
A little goes a long way I have found.

I am having issues trying to do the same thing on my 9503. When I made the mix my throttle was moving at full travel and binding.

Try Revesing the mix program,, then use the offset function to shift of the scale up on your graph.
IE: meaning ,,I belive you said you have the smoke pump on the gear channel,?? I set mine up on aux two, any way my window say throttle to aux 2 ,, not aux 2 to throttle,, try switching a reverse instruction someplace and it should fix it.or maybe the mix percentages are backwards ,I dont know how you set up the mix..
