JR function fest...

[Henderson,Eric]

JR has been using similar code sets and friendly logic since the JR Galaxy days. Code 17 does several neat things and you soon remember the one that turns off the flap trim if you are flying aerobatics as opposed to scale etc.

On radios like the 347-388 etc. and 8103 you inhibit the flap knob with a separate code. On the 10X and 10SXII it is in the menu for wing type flaperons because you are using a flap channel as an aileron.

Quite a few of my friends have moved over from other radios but still hanker after certain functions. One is throttle kill. Not usually needed because the JR has a fast action mechanical trim on the throttle. It can easily be done, however, by just mixing an increase in throttle channel throw with the throttle channel and putting it on a mix switch. (Ch 1 to Ch 1).

A devout ex-Futaba guy wanted a throttle trim on the left hand 10X ratchet. This is the above mentioned flap lever. It can't be active if flaperons are being used, Hmmmmmmmmmmmmmmmmm.. Not being able to resist a challenge, this is what happened.....

1. Use Code 17 to turn off (INH) AUX-1 (this will make the control lever inactive on the flap channel but usable for something else.
2. Open up a mix and select Channel 6 (Flap) to 1 (throttle)
3. Go to third page on the mix option and under MASTER select origination lever (ORIG)
4. Now go back to mix % page and select how much throttle trim reduction you need from that lever.

The channel six lever now works as a throttle trim.

Personally I would never use that option. I do use a hi-low idle option by mixing ch-1 with ch-1 on the MIX-SW. This is very good for landings if your engine runs a bit faster at the end of a flight. just as I hit the threshold of a landing approach I drop the rpm's. I have found that "throttle-kill" actually is not good because the plane does not slow down as much if the engine is not running.

A tip is to also use Code 75 which displays all the channels and how they move so you can check to see if you have introduced any unwanted mix activity.

Regards,

Eric.

I have a plane set up with flaperons, meaning that one aileron is plugged
into "aileron" and the other is plugged into aux 1. I selected wing type
"Flaperon" so that the ratchet tab on the side will raise and lower the
ailerons if desired. How do I turn that tab thing off, so that I don't
accidently knock it and raise (or lower) my ailerons?
