Okay i have it go to the edit menu under planes make sure you have a plane renamed for this use.

then go under miscellaneous:
then look at the bottom of the page wow it says let the radio control smoke of course click on that. make sure under the servo menu you have smoke controlled on channel 7. Wow we are smoking now TME pump and all.
I hear that it makes a mess to clean up on the plane well i am getting ready to find out.............
