Well, as I've mentioned before...I have one particular MM that has really treated me right. I don't know that the others that I have wouldn't, but this one has done all I've asked of it. Just keep in mind that I am running a relatively mild motor (9XL) in a relatively light truck (8ight) with conservative gearing that gets me around the track quickly. With the setup that I have right now, the MM is buttery smooth with the Feigao motor on 4S geared at 14/46 and 16/46.

Due to the Neu motor issues with the MM, I am now back to considering the Lehner 1940/9 (or maybe the 8); but the only place that has them in stock is a place that I refuse the do business with.

I would agree that the Quark is smooth, but it also starts rather abruptly too. With the MM I can start off at a crawl and gradually build up speed. Once the Quark kicks in, it's moving at faster than a crawl.
