On the JR 10SXII radio it is possible to use the flight modes as inputs to any mixer along with the Hover Pitch, Hover Throttle, High Pitch, and Low Pitch knobs. The five mixing channels we want are as follows


Channel Normal Mixing Origin Mixing
5 Gear Flight Mode
7 Aux2 Low Pitch Knob
8 Aux3 High Pitch Knob
9 Aux4 Hover Throttle Knob
10 Aux5 Hover Pitch Knob

When you use channel 5 as the mixing channel it shows up as gear. This is connected to the gear switch. For the standard mixers you will see a NORM with sel below it. Pressing the select changes this to INCL. Pressing it again changes it to ORIG. At this point the Gear changes to FMOD. Now the master channel is the flight mode and the master output is as in the table below


Flight Mode Output
Normal 33%
Idle Up 1 50%
Idle Up 2 67%
Idle Up 3 84%
Idle Up 4 100%
Throttle Hold 0%

Since the outputs are discrete steps rather than a variable channel, a multi-point mixer is more suited. Using a multi-point mixer you must select the third page to enable the ORIG functionality.

Using the flight mode as an input to a mixer is useful when using a governor as you can change the RPM of the governor depending on the flight mode. You could also change the gyro gain in the same way.

Using Redundant Batteries PDF Print E-mail

Using two battery packs on your receiver is a great way to add redundancy to your control system. It's a shame to have your pride and joy fly away due to a bad cell. All that is required is two battery packs, two switch harnesses and a Y splitter. The connections should be as follows:





I have heard people say that you can not hook to batteries in parallel. The argument is that as one battery fails the other pack will charge it and loose all its capacity so they must be isolated by diodes. This is simply not the case. NiCad batteries take a lot of voltage to charge them up. Charging a 4.8V pack takes a minimum of 5.6V to initiate the charge process. I fully charged pack can not supply this much voltage so one pack will never charge the other. However, you can not charge 2 packs in parallel. This is why 2 switch harnesses are required. Each pack must be charged on its own circuit. The battery packs do not even have to be the same capacity but they must have the same number of cells.
