zbp, it's starting to get hot down here. In the 90's. I would be interested in a Quark case, although it would tick me off to no end to put it into a nice case and have it blow anyway.

bdebde, I never had any trouble running nitro. I really had the touch when it came to those engines. I had to tune like everyone else, but I usually spent much less time doing it. I only ran two engines and knew them intimately. The O.S. RG and the Novarossi P5X. Both great engines, if you know what to do with them.

I'm telling you, if the Lehners were available, I'd jump on one and stick with the MM. What sucks is that I found myself afraid to squeeze the throttle with the Quark because I'm afraid of hurting it. I never have such worries with my MM controllers.
