<span style="font-size: small">Electrifly Silver Series Brushless ESC's, 60A and 80A
</span>1. The larger Electrifly 60A and 80A ESC's come from a different manufacturer, and are completely different in configuration to the smaller ESC's 8 to 45A.
2. The 60A and 80A ESC's can be programmed using a card (the smaller ESC's cannot be programmed). My guess is that these larger Electrifly ESC'sare probably made by Sunrise Model http://www.sunrisemodel.com/ -because the program card looks very much like a Sunrise Model card. We cannot see the program card from the front on the Electrify webpage, however the rear view and the pins of the card look like a Sunrise Model card - http://www.electrifly.com/miscproducts/gpmm1895.html.
3. Also the back side of theElectrifly 80A ESC looksidenticalto the back side of a Jeti Advance 90 Pro ESC, and also to the back side of a Jeti Advance 90 Plus ESC (see pics below, left pic is Electrifly 80A, pic onright of this is back side of Jeti Advance 90).
4. The Jeti Advance series of ESC's are known to be manufactured by Sunrise Model -the program cards for Sunrise Model and for the Jeti Advance ESC's are identical (see pics), so these ESC's must come from the same source.
5. Since it is clear that all Jeti Advance ESC's are made by Sunrise Model, and since the back side of the Electrifly 80A ESC looks identical to the Jeti Advance 90A, and since the Electrifly program card looks like a Sunrise Model card, then it seemsvery likely that the Electrifly 60A and 80A ESC's are manufactured by the Sunrise Modelfactory inChina.
