Check out the new improved Power HD B4S Brushless Servo - 32kg/cm (444.4 oz/in), 0.065sec 8.4V - (Super High Speed and SR/SXR/SSR/SUR/SFR Compatible)

The Power HD B4s high voltage servos are made with brushless technology. Brushless servo motors consistently provide more torque and power per gram of motor weight, while simultaneously being more efficient than either their brushed or coreless counterparts. Brushless servo motors are extremely tough and precise. They excel at relentless, cyclic, full speed direction reversals, handling them with ease. A very desirable characteristic for a servo motor. 

The brushless motor spins titanium and steel gears that are supported by bronze bushings and dual ball bearings on the output shaft. The main body of the servo is machined from aluminum and houses the motor, potentiometer and PWM / ESC board. 

These servos are lighter, more torque and perform better than the previous B4 series. They run cooler and quieter and with less vibration - because there are no brush arcings, the radio frequency interference and electronic noise is also significantly reduced.The full CNC aluminum housing, HV and the new brushless technology gives you the best strength and speed while being incredibly efficient and long lasting.

The SR/SXR/SSR/SUR/SFR multi-mode competition-level servo, overcomes the issues of incompatibility between the multi-branded models. Designed with the convenience of "Automatic Matching" that allows you to plug and use immediately without the need to be tied to the same brand.

So now the only question is - why are you still reading this? Go buy your Power HD B4S HV servos before they're gone!

LiFe Batteries 2S

Description:
Our LiFe Batteries (also known as A123 Batteries) have huge advantages over most other options.

1) LiFe Batteries are lightweight - as light as Lipos
2) LiFes are safer than Lipos (do not combust easily like lipos)
3) LiFe Batteries supply a constant voltage (They stay right near 6volts from start to finish ensuring consistent flights)
4) Run Life batteries to your servos and ignition without regulators (For extra caution some people run a regulator to their ignition still)
5)Life's have a high Charging Capacity. Charge up to 5amps, allowing you to charge them up in MINUTES!

The 2100 or 3000 Mah can be used as a SINGLE battery system for 30cc planes. (we recommend spliting the lead and put 2 JR leads on, to run to the receiver and the other to ignition). You can also run a single 3000 Life Battery on a 50cc Plane.

The 1450mah LiFE Battery is a great option for those that want a separate battery for ignition and receiver (if you are running FM or hesitant to use a single battery system). The 1450mah Life is a great battery for the ignition for either a 30cc or 50cc sized plane

We recommend the following:
On the MXSR (2) 2100mah, or 1 3000mah placed on the mount box or front of the plane. It is a bigger plane and will do well with the extra voltage and weight.
Other 30cc planes - (1) 1450mah for ignition, (1) 2100mah for receiver or for a lighter set up
(1) 2100mah for both (split the wire to 2 leads) OR (2) 1450mah (one for ignition one for receiver).

50cc sized planes (1) 1450mah LiFe battery for ignition and (1) 3000mah LiFe battery for receiver or, for a lighter set up
(1) 1450mah for ignition, and (1) 2100 for receiver OR (1) 3000mah LiFe for both receiver and ignition
