Talon 90 is ideal for helicopters drawing 2,000 watts on 6S. It’s a great fit for extreme 500 and 550 class helis and sport (6S) 600 setups. Of course, Talon offers Castle’s industry-leading helicopter functions, such as the unbelievable direct entry governor mode. Simply type in the desired RPM using a Castle Link USB adapter (sold separately) and the free Castle Link GUI running on a Windows PC!
