I also want to say (as I know this will get asked) that both MMM ESC's are working perfectly without any mods what so ever. The V1 is in the 8ight and the V2 is in the CRT.5. The 8ight-T will soon be receiving a V2 from Mike within the next couple weeks. And a 6s battery is already on the way for it as well.
The electronics in each are:
CRT.5: MMM, Neu 1509/1.5y, Flight Power 4s 4270mah lipo, Hitec HS-5245MG, RCM motor mount
8ight-T: MMM, Neu 1515/1.5y, Thunder Power 5000mah 6s lipo, Hitec HS-5955TG, RCM motor mount, RCPD battery tray
8ight: MMM, Tekno Neu 1515/1y, Hyperion 4s 5350mah 4s lipo, Hitec HS-5997TG, RCM motor mount, RCPD battery tray
