The Bristol Beaufighter and the Messerschmitt Bf110 are electric powered. Under normal circumstances twins are avoided because of the problems of asymmetric thrust if one engine stops. With electric motors this does not happen so safe control is assured at all times. In the early days of electric flight power to weight ratio was low and some models tended to wallow around looking most unconvincing. We were determined that this should not be the case with our own designs and the Beaufighter and the Messerschmitt look highly purposeful in flight. They are fast and they sit in the air like their full size equivalents.

This picture of a Beaufighter is from Michael Krone in Germany. Fitted with brushless motors and full retracts it flies like a dream he tells me.

The "Whispering Death" packed an incredible punch, four 20 mm cannon and six .303" machine guns. This heavy armament soon became justly feared by enemies on all fronts during WWII.
Initially many thought that the Beaufighter was an aeroplane too heavy and too large to be successful but this fear was dispelled when it was found that the bulk was ideal to accommodate the early night fighter radar that was available.
The prototype Beaufighter first flew in July 1939 with the first ten production models reaching the RAF in August 1940.
It was a very adaptable aircraft and served in night fighter, ground strafing, and torpedo bombing roles. Truly a complete aeroplane.

Construction:
The construction of the Beaufighter is conventional comprising a built up wing and fuselage. Mouldings are supplied for the nacelles, cockpit and nose cone.
As with all electric powered models weight is extremely important. The weight of batteries, motors, speed controllers and radio gear is fixed to a large degree and cannot be reduced. We flew the model at an all up weight of 2.4 kg (5.2lb) using standard servos and 2 off 7 cell 1800mAHr battery packs. Its performance and duration was extremely good; it flew like fighter.
You could save some weight with miniature servos and 7 cell battery packs made from smaller cells but do remember to build light.
We have designed the structure as light as we think practical; don’t be tempted to add weighty extras.

Balancing and Control Set Up.
It is crucial to balance the model correctly. With the model fully assembled in its ready for flight state support it on your fingers at 90 to 100 mm (3.5" to 4") from the wing centre leading edge. The model should balance slightly nose down, (about 3 degrees), in a gliding attitude.
Move the front battery forward or back to achieve this. This should be all you need to do but if further adjustment is necessary move the elevator servo and or receiver. Our model utilised BEC circuitry and therefore had no receiver batteries; if you use these then they will give you further scope for adjustment. As an absolute last resort correct the CG position with lead installed at the furthest point forward or back that you can get it.

Set the control throws to:
Ailerons:  +/-  16 mm
Elevators  +/- 10 mm
I
f you do not get exactly these figures do not worry; try to get within 3 mm (1/8").

Flying.
The Beaufighter flies very smoothly and those with previous experience of aileron models will have no difficulty whatsoever. Get someone to launch the model for you until you are fully familiar with it. It should be given a good running push into wind and should leave the launchers hand horizontal. Let the model gain some speed by flying level for a few seconds and then climb out.
Landing is simple, just pick a smooth patch of grass and flair out onto it.
