For those of you with radio's that allow mixing of channels you can set-up differential thrust on the 

motors. As the H-King Lancaster does not have any working rudders this is a big plus in improving the 

flying characteristics and makes it even more fun to fly. You need a radio that has at least 3 "Free 

Mixers", that is 3 mixers where you can assign which channels you want to mix rather than pre-set 

mixers. You will also require a minimum of a 6ch radio and receiver so that you have an AUX 1 channel 

available. We cannot go into all the different types of radio's and how they are mixed but we have given 

some guidelines below which should help.

1. First thing you need to do is remove the Y lead from the ESC leads coming out of the wings (if you have

already fitted it). You then need to plug one lead into your throttle channel and the other into AUX 1.

2. The first mixer you need to make is "Throttle to AUX1". So Mixer 1 is THR>AUX1. Rate will be + or -

100%, or - 100%, Trim (Active) and Switch (On). If you have a display monitor on your transmit-

ter then at this stage check that the throttle and AUX 1 channels move together. If they move in opposite

directions reverse as necessary.

3. The second mixer you need to make is "Rudder to Throttle". So Mixer 2 is RUD>THR. Rate will be -25%

both ways (you can use more but we have found this is more than sufficient), Offset 0%, Trim (Inhibit),

Switch (Select the switch you prefer to use on your Tx such as Gear etc).

4. The third mixer you need to make is "Rudder to AUX1". So Mixer 3 is RUD>AUX1. Rate will be the

same as you set in Mixer 2, ie, 25% each way or whatever you set, Offset 0%, Trim (Inhibit), Switch

(same as you selected for Mixer 2).

If you get stuck there are plenty of video's on YouTube which are very easy to follow for quite a few

different makes of transmitter.

Please ensure that the Lancaster balances 

ready to fly with the battery installed 

between 50mm and 60mm from the

leading edge of the wing. For initial flights 

we recommend that you balance your 

Lancaster near the forward 50mm mark.
