OK, I can't stand it. I have two, yes two, H9 1/4 scale Caps, one with a saito 1.80 and the other with an MVVS 1.60 gasser. I want to put smoke on the Saito mounted plane. Here is my question. there is not a lot of room in the 1/4 scales with dual elevator. For those that have done it, were have you mounted the smoke tank, how large was it, and how long did it give you smoke. thanks in advance.
