smoke system questions

[robertp17]

Hey guys I have a few questions concerning smoke systems. I want to put a smoke setup on my 2.6 comp and want to know what kind of setup will work on a 35% airframe. I have a TME smoke pump that I had on a 50cc that worked well and it had a seperate battery for the pump and used a spare channel in the receiver. Will this setup be able to supply the volume of oil that a twin will need to get lots of smoke? Also I have a brushed harris pump that I have never used and am a little scared to use it on a 2.4 spektrum system as it plugs into a spare channel and uses your receiver pack to power it . Seems like a big current draw thru the receiver to me. Before you ask I have several options for receivers, an r921, a 9100, and also have a powerbox if that will make a differance, I would rather keep it simple and ditch the powerbox. I am running one servo per surface. My main concern with the harris is, is it going to drop my voltage to near 3.5? I will be running (2) A123 packs. One more question, where can you buy the check valve that goes on the outlet line to the exhaust and is it neccesary? Thanks for any and all input
