Castle Creations Talon-15 15 Amp Brushless Aircraft/Helicopter ESC. We packed as much brute power and intelligence into this tiny layout as we possibly could and came up with a 15 amp controller with ability to sustain an 8 amp BEC! Talon 15 measures just 1.1" long and is under 0.6" wide! At nearly the size of a quarter, this ESC supports an outlandish 8 amp peak BEC with input voltage of 5.5 VDC. Applications range from foamies, small light weight electro-glider to micro and sub-micro helicopters running up to 4S and pulling 15 amps. As with any Castle ESC, the Talon 15 offers Castle’s industry-leading functions, not to mention easy programming using the Castle Link USB adapter (coupon for free Castle Link included), or the Castle Field Link Portable Programmer (sold separately).
