9 Channel assignment in jet application...
Hello Jet community,
I'm looking forward building my brand new F-18F this winter,
now I try to make the best channel assignment with my
X9393 - 9channel transmitter for handling all the functions
within this model.
So my thoughts are:
I want to use the AR9100 receiver.
First of all I want to post how I'm planning to assign the channels:
Channel1: Throttle/Turbine
Channel2,5: Aileron (2 Servos)
Channel 3: Elevon (2 Servos)
Channel 4: Rudder (2 servos)
Channel 6: Gear (electronic valve)
Channel 7: Flaps (2 servos)
Channel 8: steerable nosewheel
Channel 9: Brake
so far, but now perhaps some issues that could occur with this
assignment ?
- In the future I would like to install a smoker - this would
mean, that I have to spend either one seperate channel for the
smoker pump, or I have to mix it with e.g.the Channel 9 (Brake)
So there is the possibility to mix the brake (servo mechanical valve) with
channel 3, the elevon function.
If I do so, are there any issues by using 3 servos on one channel - can
the receiver handle this - so all the signal cables from the servos are in
parallel and would get the signal from channel 3 elevon ?
I would be pleased if someone posts his experience in using a 9channel transmitter
in jet applications with brakes and retracting gear.
Best regards

I would use a Matchbox on the flaps. Settings up flaps is a breeze with one.
Also using another MatchBox on the nose wheel and rudders would freeup one channel.

Tim -
One way to save a channel is to get the differential on your ailerons mechanically. You can offset the arms on the ail. servos to give you more up than down. That frees up channel 5 for whatever you want.

Use a combo ret/brake valve to save a channel. Use a Match Box to slave the steering to the rudder channel (or Y harness), another channel saved. Use one of the open channles for the other flap. Use the last open channel for smoke.
Done!

RE: 9 Channel assignment in jet application...
...thanx for your help - regarding saving the channel for the aileron and/ or flaps I think I use for both
a y harness also for rudder and elevon !
When all functions are in center position and the min max is OK - there should not be any issues with bad trimmed
wings.
And all the Hitec DS are programmable.

RE: 9 Channel assignment in jet application...
You could also use one of these to save a few channels:
http://www.electrodynam.com/rc/EDR-125/index.shtml
Combines mixing down elevator to brakes and rudder to steering. Also centers the nose gear before retraction and locks the steering servo in center when flying to prevent pull-pull cables getting tangled. Prevents accidental gear up command when you turn everything on as well.
Lewis Patton has one in his Century Jets F-18 that he has been flying all year.

RE: 9 Channel assignment in jet application...
JR,Futaba,Smartfly all make "matchbox" devices. JR also makes a Channel Expander that allows using one channel to control multiple actions from one switch. Smartfly,Powerbox,Emcotec,etc. offer servo expander devices. These are in addition to the products already mentioned. There was a thread on RCU about somebody using a Spektrum 7 channel radio and was able to fly a very complex jet by utilizing the 7 channels plus a combination of some of these other devices.
