Powerbox Systems Sensor Switch

Product Reviews

power box  A lot of people seem to be looking to power their models now with lipos therefore needing to use regulators dropping voltage to save burning out servos. Here's a heads up on an excellent little digi switch that combines everything you need.

I've noticed that quite a lot of places are now selling the Powerbox Sensor Switch TwinBatt for between £60-£70.
This is the digi switch I have used in both my F15 and Boomerang. Twin ThunderPower 2100mah 7.4v Lipos run into the switch, and a regulated 5.9v comes out the other end to power rx/servos.

Here's the blurb.
Power handling up to 5.0 Amps (according to heatsink) For 7.4 Volt LiPo batteries (PowerBox Battery) or 5 NC or NiMH cells Two independent linear voltage regulators, supplying 5.90 Volts Two independent electronic switches Two volt controller ( in 4 steps ) for each battery NEW Two Low voltage memory for both batteries NEW SET button for On / Off switching protection LED indicators for both power circuits Operating voltage range 4.0 to 9.0 Volts Temperature range -10° to +75° C Voltage loss approx. 0.35 Volts Weight only 35 grammes incl. all cables


No issues using 5.9v on JR servos. JR advise not to run their servos at 6v unless specifically stated. 5.9v is around what a fully charged 4cell Nicad puts out anyway.

All very neat and if the electronic switch fails it fails to 'on'. If one power supply fails, the other takes over- redundancy!

Recommended. 
 

 

Cessna Skylane 50

Product Reviews

cessna A Review of the Cessna Skylane 182 from CMPro.  One of the all time and favourite aircraft is the Cessna Skylane, the family saloon of the aircraft world.

Over the years there have been various versions, more powerful engines and even retractable undercarriage for the full size craft.

The model we will  be reviewing is the CMPro (China Model Productions) Cessna Skylane 182 (50 size) ARF.

The model came in not too large a box considering, about 4 feet, just long enough to accomodate the fuselage with it's integrated tail fin.  The components were reasonably packed.  Small items came in various plastic bags.  CMPro have jumped forward with this kit - supplied is an electric option.  A ply mounting box with down-thrust and right-thrust angles built in.  The box is marked which way to be installed following the option in the instructions.  As you will see later, the electric option would keep the scale model's lines perfect.

Boomerang 40 Trainer

Product Reviews

trainerThe Boomerang Trainer features a large wing area and a docile semi-symmetrical wing section.  A great performing RC trainer with original Australian trim - highly visible colours.

With it's huge wing area and semi-symmetrical wing section gives the newbie an easy and forgiving flight. In the fuselage the R/C compartment with pre-installed servo tray allows for virtually any make of servo/receiver and battery combination. A bright colour scheme helps make attitiude recognition easy in flight. For the experienced pilot, use the Boomerang to have sport fun at weekends and practice some new manoeuvres without risking your upmarket or scale models.

The model is immaculately factory-built, covered and decorated to get you into the air as fast as possible. As with all Seagull Models, a comprehensive fully-illustrated manual is included too and is written in  comprehensible  English.   I have built three of these models made in Vietnam by Seagull Models. Wing is secured to the fuselage by heavy duty elastics for easy dis-assembly for transport.
