Scorpion A-4220 Pro PNP Combo (6s / 15-20cc /70E+ / 2550+w) PERFECT for our Extra and Laser 70E Planes

n combination with the new A-Series motor line debut, RWRC is pleased to announce the new "PLUG-N-POWER" combo kits! We wanted to take the guess work out of Electric Power Systems, and provide our customers with a simple, convenient and reliable power system for their 70E+ / 15cc sized airplanes commonly used in 60"-64" Acrobatic Airplanes. The A-4220 PNP Combo is the solution. This pairs our high power and high efficiency A-series motors with one of our suitably sized, preprogrammed, Tribunus ESCs! Providing you with a tested, proven, and convenient power system combo, which is sure to provide you immense power, at the best efficiency! This PNP combo is ready to easily bolt on, and give you the power you need, with the efficiency you want.

The A-4220 PNP Combo comes in 2 variations. A "Sport" version and a "Pro" version. The Sport version is useful on sport airplanes using lower power servos, and smaller prop, whereas the Pro version can handle high torque servos and larger props for extreme use cases!

Booma RC Wallaby Switch II with Active Dual Battery Redundancy and Voltage Monitoring

Description:

Booma RC

If you want a switch that offers complete dual battery balancing and redundancy with an ultra-small footprint for your scale model then look no further. The new Booma RC intelligent redundant battery balancing switch is the answer.

This switch works with any single or dual battery system. Works with battery chemistry and voltage range from 2.5v to 28v. It comes with a Pin Flag and Ultra Bright Blue LED which can be mounted discretely on your scale model. The Pin Flag controls the internally mounted switch and battery redundancy circuit. The result - beautiful scale appearance with dual battery redundancy peace of mind.

This new balancing technology offers zero voltage drop battery balancing and redundancy which means it can handle huge loads without generating heat. This also means your receiver and servos get all the power unlike conventional battery balancing which loses precious power as heat.

Package Includes:

1 x Pin Flag Switch with mounting hardware.

1 x Ultra Bright Blue LED with mounting hardware.

1 x Dual Battery Balancing power switch circuit.

2 x sets of Input and Output JR connectors.

Specs:

Ultra low foot print for the best scale looks.

Works with single or dual battery configuration.

Works with all battery chemistries. LiFe. LiPo, Lion, NiMh, NiCD. Battery voltage range can be from 2.5volts to 28 volts.

Capable of handling input voltages up to 28volts.

Minimal external footprint - All you see on the outside of your model is a 3mm Pin Flag socket and (if required) an ultra-high bright Blue LED. The Pin Flag controls the internal power switch and dual battery redundancy.

Full Dual Battery Redundancy - If one battery fails the other battery takes full control.

Maximum Battery Power Balancing - In a dual battery system HS1 draws current proportionally from both batteries while moving both batteries to a complete load balance situation. This means you get the maximum capacity out of both batteries all the time.

2 x 25 amp independent circuits. HS1 is 2 x 25amp circuits into a high power matching battery redundancy circuit. HS1 actually uses 4 x 50 amp rated FET circuits for battery power matching. We passively rate HS1 at 25amps per circuit.
