Serpent S811 Cobra updated radio box

Serpent have introduced a new radio-box for the Serpent S811 Cobra, offering a solution for the brake-throttle servo issues, by placing the throttle-brake servo much further forward. Today’s modern generation of digital servos don’t seem durable enough to absorb the hard bumps which occur after landing/jumps and as too many drivers had issues with this, they have come up with this solution. This upgrade set will be offered free of charge to all Serpent Cobra owners and dealers and distributors with Cobra S811 kits in stock, will also receive a free upgrade set for the stock they carry. Available late November.

Changes and advantages
– Servo is relocated the farthest away from the engines vibrating epicenter.
– Servo is relocated the farthest away from the abuse on the rear end, whether under jump landings or rear end bump impacts.
– Transponder was moved further forward, and both older and also latest version transponders (with small holder) fit.
– Carburetor was rotated for easier access of high speed and idle speed needles
– Brake Ratio was improved to 1:1 ratio to take the strain off the servo
– Servo pull speed was improved 10% for better response.. If you use a servo that was .13 in transit speed. it will now perform like .11 on throttle, but still remain .13 on brake pull.(This improves response on throttle, but retains torque on braking. (Also though the speed is adjustable by the user. If he wants faster response than provided by way of shims)
– New layout helps retain almost the same balance from previous layout
– Servo heights are now more adjustable so you can always maintain lowest possible CG, using servo spacers
– Servos are mounted in a new way that reduces the need for extra inserts and always maintains a safe distance from the servo walls.
– New styling matches the overall cars appearance even better (although of course this is subjective to all)
– Double collar now with machined diameter, so you can adjust the drag brake on the fly during warm up of a race
– Servos can be changed more easily without having to remove radio tray
– Fits still by use of original S811 Body shell
