SCORPION A-7441-180kv (V2) Motor for Giant Scale Airplane (12S 100-120cc)
The Scorpion A - Series line of motors was designed to be the most optimal and premier choice of motor for your freestyle or UAV airplane. We have achieved incredible performance through incredible efficiency. By optimizing the magnets in the rotor, and using the best quality 0.2mm thickness silicon steel stator sheets, and single strand enamel coated copper wire windings rated above 200C+, the performance and efficiency results are unlike anything we have seen before! Combined with a robust design which has been tested extensively by our world class team pilots for longevity and reliability, we feel this motor checks and exceeds all measurable categories! The A-7441 was designed specifically for airplanes requiring a 100cc - 126cc equivalent gas engine, or other airframes requiring up to 9,300w of power. Recommended Prop Selection :
Recommended ESC -: Tribunus II+ 14-200A ESC SBEC + Scorpion 40mm High Speed Cooling Fan V2 NOTE: Due to the large size of airframes in this class, normally the battery wires must be extended. Running to long of battery cables WILL damage ESC and void your warranty. Precautions must be taken. We recommend the use of the Scorpion 1880uF Capacitor / PDB Board Tutorial / WARNING about using ESC's with a Power Supply, or Long Battery Cables NOTE: Due to the large size of airframes in this class, attaining proper ESC cooling can be difficult. The ESC MUST have direct access to airflow using baffles directing air directly to the ESC. Simply adding a hole in the cowl is not suitable, and air must be carried directly to the ESC via baffling. Acrobatic Weight Range -: 11.80kg - 27.21kg (26.0lbs - 60.0lbs) Sport / UAV (single engine) Weight Range : - 18.67kg - 56.80 kg (41.7lbs -125.2lbs) Scorpion A-7441-180kv - Santiago Perez Specifications

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)
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)Check out the new Power HD 0804HV Brushless servos! These are great to use a throttle servo and can be used in systems with other high voltage servos! The Power HD 0804HV high voltage servos are made with brushless technology. Now - we've heard about this "brushless" stuff before but it is time to ask the question on all of our minds - why is that so great? Take a brushless motor for example - no brushes in a brushless motor (no kidding...) nor does it have the commutator - instead a small circuit board coordinates the energy delivery to the windings. Think about this technology being used in a power tool - since the electronics communicate directly with the stationary windings the tool can adapt to its surroundings - only using enough juice necessary to accomplish the job. So if you are using a brushless drill to drive a screw into Styrofoam - it will sense the lack of resistance from the foam and pulls only enough charge from the battery that it needs. Whereas a brushed drill will run as fast and hard as it can no matter the job simultaneously wasting your battery life. "What the heck does that have to do with my servo?" Well now they are incorporating that smart technology into these HD 0804HV high voltage servos - so they are not going to be sucking the life of your Redwing LiFe battery when it doesn't have to - which means not only would you be getting a great and powerful servo - it's smart! Your "LiFe" will thank you. These servos are high efficiency and perform better. They run cooler and quieter and with less vibration - because there are no brush arcings, the radio frequency interference and electronic noise is significantly reduced. All aluminum housing, high voltage and the new brushless technology gives you the best strength and speed while being incredibly efficient and long lasting. So now the only question is - why are you still reading this? Go buy your Power HD 0804HV servos before they're gone!
