FLYING THE BF.110:
The Durafly Bf.110 may be close to scale in its outline, yet it flies exceptionally well for a twin
engined model. With its counter rotating configuration and powerful set-up, the Bf.110
enjoys a great flight envelope, maintaining its maneuverability and aggressive stance in the
air throughout the speed range. Use of rudder in the air (although not completely
necessary), does add its overall flying prowes when used in turns and of course
complements the steerable tail wheel on the ground. The Bf.110 is capable of all manner of
scale and sports maneuvers yet will not bite you in the stall, benefiting from very benign stall
characteristic. With the recommended 2200mah 3S lipo you have a good combination of
power, with respectable flight times. You should typically expect flight times of approximately
7 minutes with varied throttle use in flight. For greater duration you can of course fit a higher
capacity pack (the Bf.110 will handle the extra weight). On the ground the handling is
excellent on both short grass and paved surfaces, though hand launching would be advised
if you're flying from longer grass.That said, this Bf.110 does hand launch easily.
Taking off directly into wind should require no more than 3/4 throttle to be off the ground.
Care should be taken to increase throttle slowly during taking off, allowing time for any
correction to direction with the rudder/tail wheel, whilst allowing speed/lift to gradually build.
It is recommended that some up elevator be held in for the initial rollout to help keep the tail
down whilst you build up speed, and to prevent the model from nosing over. As momentum
starts to build, gradually reduce the amount of 'up' you have held in to allow the tail to lift.
From this point the Bf.110 should take to the air with minimal amount of further 'up' elevator.
If you do wish to hand launch your model, this should be done with full power into wind and
at a slightly nose up angle with the wings level and the landing gear retracted. Climb out
from hand launch is good, with no noticeable loss in height immediately after launch.
Flying a twin engined model is an exciting and unique experience yet has traditionally been
more of a challenge. With the Durafly Bf.110 however you needn't worry. It easily handles as
good as any of the single engined warbirds in the range whilst, providing that twin sound and
experience in the air. All basic aerobatic maneuvers can be done with ease at full throttle
(even more so with coordinated stick inputs). For closer to scale flying you'll want to bring
the throttle down to approximately 3/4 throttle. Here you'll benefit from a more realistic speed
and a slight lengthening of flight times, whilst maintaining complete maneuverability. Also to
avoid over heating your motors and ESC's, it is generally not recommended to fly on full
throttle for the entire duration of the flight. In slow flight the Bf.110 still maintains a good level
of control and authority for both low/slow fly-bys and landings. The Bf.110 does land easily
and will not present a challenge for pilots with low wing experience. When you are ready to
land, lower the gear on the down wind leg to help the model bleed off excess speed ready
for when you make the turn into the approach. A high angle of approach is recommended as
this will help maintain a steady descent rate when coming into land. The Bf.110 has a
reasonable glide for a twin, but the drag of an additional prop does need to be taken into
consideration. So, always 'fly' into your landing with the combined use of throttle and
elevator. As you flair for landing, be sure to hold in some additional up elevator once you’ve
touched down. This will prevent the bf.110 from tipping up onto its nose especially when
landing on longer grass. Once down, you can enjoy the exceptional ground handling of the
Messerschmitt thanks to its tough metal trunnion electric retracts and steerable tail wheel.
Happy flying and thank you for choosing Durafly.
