I just built and flew my cermark pitts with a g26 RCignition conversion and it is not under powered at all. Take offs are quick and smooth, landings are quick and bouncy. First attempt and I missed the runway, bring em in under power and hold her off til last second, cut power and roll out. I am putting a skywriter smoke system in and am having troubles on the bench. Does the engine need to run to get it pumping?
I blew thru it to prime it, hooked up a 6 volt btty and plugged into chnnl5 on my 9cap and nada, nothing. No pump noises at all. I set the epa on servos all over the place- nada nothing.
this a great flying plane, 2 clicks of left ail and one of down elev and it was hands off for a 1/4 mile.

I need smoke on this so any help is appreciated
