Nice to hear. The quirks and price were the main reasons why I never considered them in the past. One issue down, one to go. If only they could lower their price a bit! I love the fact that they don't need fans (no surprise there I'm sure). I have a feeling a lot of BL companies are gonna have to lower prices if they want to stay competitive...
I burned 2 MGMs in my early brushless days, but I think I could put the blame more on me it was a MGM 160 amp 8s controler, and I was running 8s with a Lehner 2240 10turn, geared to 65mph. Now I would just run 8s, a Neu 1521/1Y geared to about 50, sounds similar to what you are running.
