Flying the H-King Lancaster
The Lancaster is not a difficult model to fly, it is not for beginners but you do not need to be highly experienced
to enjoy flying it. Before you fly please make sure your batteries are fully charged, the center of gravity is within
the recommended limits, you check all the controls are working correctly, and you have carried out a range
check on your radio.
Select a grassy, open flying area away from roads, trees, pylons, water, crowds of people, and not near full
size aircraftactivity. Also make sure you pick a dry day with light winds for you maiden flights.
Once all above is sorted and you are in your designated flying area switch on your transmitter and then plug in
your flight battery, wait for the ESC's to arm. Close the bomb bay doors and turn the model over, hold the
model securely and check the controls are working correctly and in the correct sense, open the throttle a small
amount to check the motors.
If you have a helper available at this point then it is better to ask them to hand launch the model for you. If not
then hold the model either underneath somewhere near the C or G point and above your head for an over arm
launch, or on the top for an under arm launch. Point the model into wind, open the throttle to about half power
and then give the model a firm hand launch with the nose slightly up. The Lancaster will climb away beautifully
on half power and due to the contrarotating props it should climb out nice and straight, any tendency to turn
then correct with a small amount of aileron. Climb up to a safe height and fly around back over the take-off
area, trim the model at this point to fly hands off.
Once you are happy with the trim and the model is flying nicely explore the flying characteristics. You will find it
is best to keep a bit of power on in the turns, if you have set the model up with differential thrust then this helps
enormously to do nice scale turns. Low passes are a dream, the Lancaster if set-up correctly is very smooth to
fly and not twitchy. It is nicely aerobatic but of course this is not very scale like, but it is fun !!!
Once you are ready for a landing fly the model upwind and off to one side at about 150ft. Turn the model
downwind and throttle back to about a third throttle, fly downwind to a point just past your landing area. Then
do a 90° turn to put you onto the base leg of the circuit, throttle back to about a quarter or a little less, be
careful not to reduce power too much as four wind milling propellers cause a lot of drag causing the model to
slow down very quickly. Once almost in-line with your landing area do another 90° turn to line up with your
grass runway. At this point reduce throttle some more so that you achieve a nice steady descent to the landing
area. Remember on the approach that your elevator is your speed control and the throttle is your height
control. If you are under-shooting do not put in up elevator otherwise you may stall, apply a small amount of
power instead, if you are over-shooting do not put in down elevator, take some power off, but not too much.
Once over the landing area and at a height of about 5ft or less take some more power off but not all of it,
remember the drag of the propellers. At about 2ft smoothly apply a small amount of elevator so that you fly
level with the ground, as the speed slows and the nose wants to drop apply a bit more elevator, then and only
then take all the power off, you should touch-down in a flared attitude. The propellers are very resilient and will
not be damaged when landing properly on grassy areas, the
nacelles also help keep them of the ground.
Collect the model and remove it from the flying area, turn it over and open the bomb bay doors to unplug the
battery, then switch of your transmitter.
