I would like to put a smoke system on my P-51 that has a KNIGHT 100, can someone send me a link to which one is a really good one too use? This is my first smoke system and would love to put one on my Alpha trainer and pulse XT when I get it, now I am new to smoke systems and the RC hobby ( Planes) in general, how much can I expect to pay for a smoke system for a 100 Knight 4 stroke and do smoke systems only work on 4 strokes or 2 strokes? ALso how exactly do they and where do they mount too? Thanks alot and sorry for another smoke system question.
