I have a 12FG and would like to program a mode where I can flip a switch and both air. and elev. go up to stop quick on landing I've seen it but have not tried it so I was asking to try to save a little time in programing,thanks................

I don't recall ever seeing Elevators used as Speed Brakes. Usually, you would use Butterfly or Crow, where the Ailerons go up, the Flaps go down, and a slight amount of Elevator would move to compensate for any Pitch Up or Pitch Down caused by the deployment of Flaps and Ailerons. Also, if Ailerons go up too far, you can use Lateral Control.

Are you in Acro mode? If you are have you gone into your Airbrake menu and activated it? If you are in Glider Mode, then you would want to use the Butterfly menu.

Telejojo,

I have a PulseXT (tail dragger) that landed hot, and tended to bounce on landings.

So I programmed in a couple of mixes on the 12FG as follows:

1) Once on final approach, I flip a switch and the ailerons SLOWLY drop to a preset condition (maybe 20 degrees). I know, some guys like to do the slider thing and manually do it. I delegated this to the 12FG. This allows me to reduce speed without falling out of the sky.

2) After I touch down, I flip the momentary switch (upper back right) and two things happen. First, the ailerons go full up, and about a half second later, the elevator goes full up. I wanted a delay on the elevator to give the plane time to bleed off speed. Up elevator obviously glues the tailwheel to the ground.

3) After about 5 seconds, I release the momentary switch, and the ailerons and elevator SLOWLY go back to the normal position.

Now I have no-bounce landings in very little distance. Control surface motion takes on a realistic appearance as well.

Also, I have an alternate mode that does the same thing - except instead of hitting the momentary switch, the process activates when the throttle is at the zero position. So, when I land I bring the throttle all the way down (but engine still running) and the aileron / elevators go through their normal sequence.

*** PM me if you want the details, as I may lose track of this thread ***

I've logged a LOT of hours programming the 12FG, and dare say that I'm pretty comfortable with it's operation. Coming from a 9CAPS (and prior to that, a Super 7UAP), it was a bit of a shock. But this REALLY is a different class of radio. Wait until you get into "Virtual Channels". Oh, and did you know the 12FG is capable of executing a sequence of commands with a single switch? You won't find that it the manual - and doing this at a competition is against the rules... but it IS pretty nice to be able to flip one switch and see the ailerons, elevator, and rudder move in a particular timed sequence to execute a decent 3 second roll.

I want to stick it down after touchdown as my 1.60 Texan likes to bounce so you have to fly it in.No flaps.In acro mode.I saw a guy do it on a big Extra and when he touched down it stuck like glue almost like a carrier landing.

Here's how I set up my PulseXT to land without bouncing.

1) Configure flaps to deploy when SW-C is in the "DOWN" position.

- LINKAGE->FUNCTION->goto page 4/5
- VC1 should already be set to CAMBER. Scroll to the Control Column and select the control.
- Change it to SC from the hardware list.

- MODEL->CAMBER MIX
- Set ACT/INH to OFF
- Set SWITCH to SC from the hardware list
- While in the hardware list, scroll to the ON/OFF selection and set the three postions to OFF/OFF/ON. This will ensure the
- flaps are only deployed when SW-C is in the lowest position.
- Go back to the CAMBER MIX screen. Scroll to AILERON in the "Curve and Rate" section.
- In the CAMBER (AIL) screen 1/1, set RATE A and RATE B to 100. Mine was +100 each. You need to check your servo installations
- to make sure it doesn't have to be -100 for your bird.
- In the second CAMBER (AIL) screen 2/2, set the RATE 2 column to both -40%. In my setup, I left the RATE 1 column 0
- for both AIL and AIL2. Adjust the 40% to suit your needs. Too much and you will lose lateral control.
- Scroll to the SPEED section and set In and Out to both 23. Adjust this to suit your needs. This gives me about a 2 second drop.

At this point, you should check your ailerons (flaperons). Flipping switch SW-C to the lowest position should lower your ailerons.

2) Set up the AIRBRAKE. This is easy.

- MODEL->AIRBRAKE
- On page 1/4, I set the AIL and AIL2 OFFSET to +75%. Your polarity may be different.
- On page 2/4, I set the ELE OFFSET to +50%. Again, check your polarity. You want the elevator to go UP.
- On page 3/4, set ACT/INH to OFF, SWITCH to SH, and make sure it is ACTIVE when pulled toward you.
- On page 3/4 again, set the AIL IN / OUT SPEED to 10 and 23 respectively. Set the ELE In / OUT SPEED to 23 / 23 respectively.
- On page 4/4, leave as defaults.

Now, on approach, activate switch SC to lower the flaps, and as soon as you touch down, pull switch SH toward you. You can review the operation on the SERVO MONITOR.

Enjoy.

Thanks I will give it a try..................

Describe the timed switch sequence for us....
