E-FLITE 40-Amp Brushless ESC Version 2
It appears that the first version of the E-Flite 40 amp Brushless ESC was less than perfect and the new version (2) is due to ship out within a week. I bought the first version 2 months ago. It overheated and melted off the shrink wrap on the first flight. I sent it back and hadn't heard from Horizon Hobby for about 8 weeks. When I called, they said they were replacing my unit with version 2. It seems that the first version was faulty. If you had any problems like I did, take advantage of the upgrade.
