Airtech, I used neoprene to the muffler. It has been on there thru 2 flying seasons, and about 300 flights, with no noticeable damage. The Sky Writer flow is progammed thru the radio. Makes it easy to adjust. This is the only smoke system I have experience with but I dont think I would try any other at this time. My Edge has a 16 ounce smoke tank in it. I have flown a 15 minute flight, with smoke on during manuevers only. There was still about 2 ounces of fluid left. I have never tried just turning it on, in flight, to see how
Thank you much Vanguard. I have two Showtime pumps, but neither one works. The controllers seems to be toasted. I think I am going to go with the TME SmartSmoker Simple Smoke Pump and add a Perry Remote Needle Valve to it. At $90 some bucks they are not exactly cheap. Maybe the Sky Wrriter is the way to go.
I am defenitely using the Neoprene for the mufler conection, between the check valve and the injector nipple. Thanks for the information.
