Coool....The 4 seems the better runner:) That was new rings right?
They are a funny engine the 2nd generation, they are supposed to be smoother than the Rotomo, but I can get most of my Rotos to sit almost still, where as a fair few of my previous specials shake like crazy at low speed, no matter what you do to them. They also have a very small throttle margin, maybe only 3 stages, where a Roto has a more subtle and smooth increase of more stages.
I thought my head was gonna rattle off from the first one, lols.
Great job on both engines mate, and you've done well to get them running fairly clean too, and keep the costs down:)
Thanks for posting:)
