JR 11 X programing

I am redoing the smoke system on my plane. I am using a JR DSM 11X 2.4 radio. As of now, I have the smoke pump on the three position flight switch on the left side of the radio, set up as off, low and high. The gear switch is used to turn the ignition on and off. I would like to mix the smoke pump with the throttle so I turn the pump on and the more throttle I use the faster the pump turns. I don't understand the book. Would some one please walk me through the setup .I am just a Sunday flyer so that is why it set up this way.

Thank

Looks like a Harris smoke pump.

Thanks crankcase,yep that is what I have. I just got one of your star nozzles,I am not sure where to put it in the muffler. My engine is a BME 56 with a standard drop down muffler. Like the ones that came on the DA50 cc. The drawing that came with the nozzle and on the web sight doesn't compare to mine. any suggestions?

Sure thing Ron.
The instructions with your nozzles are representing a suitcase style muffler (or how I describe them) Something like a DLE or DLE rear asperated (RA) stock muffler.

The key to nozzle placement is to direct the spray across the muffler "inlet window" at something like a 45 degree angle. But not in such a way so as to spray directly into the engine cylinder or onto the piston face.

In the attached photos you can see the spray direction illustrated and why the factory 3:00 & 9:00 positions (when looking at the engine from the front) are not recommended. Rather, new smoke port taps are drilled and tapped at the 2:00 & 10:00 locations to get the spray in the ideal spots.

I'm using a JR9503 so my program mix is probably similar, but likely a little different. Hoping someone will chime in with specifics on the JR11X.

Crankcase, do you still use preheating coils for suppose to be better smoke?

You sure can. Preheating will aid in making whiter, brighter, longer lasting smoke. Here is a link to a post with a few options for various setups. The single pass through might be a good option to consider...

JR 11x programming

Well I just have to give a great big thanks to a couple RC guys who helped me out on this project. A gentleman, his first name is Bill , Flies for the JR team in California, pm me a few times and then got up early this morning and called me. He had a 11x in his hand ,and walked me through the programming of the radio with ease . Even tho I was slow to catch on, he never lost his cool . Slow and steady he went. JR should be proud to have a person of this caliber on their team. I know witch radio and products I will buy if JR gets going strong again. Thanks a bunch Bill
Second guy is Crankshaft. He also helped out with pics. and advice. With a little more work I should have this smoke system in tip top shape putting out billowing clouds of smoke for next weekend .
Thank you Crankshaft.
