I purchased an Ultra Stick 40 and have a couple of questions which don't seem to be addressed in the manual:

1) How do I set it up with Quad Flaps using a Futaba T6XA radio? i.e. which sockets do I plug the servos into?

2) How long should the servo extensions be that I need to purchase, and which ones do I need to extend? The two ailerons? The Quad Flaps? Do I need a Y extender?

Any help is appreciated.

Can't help you with #1, sorry.

As for the wiring - I used two 12" extensions, 2 18" extensions and 2 4-pin Deans plugs to make up a custom wire harness for the wing.

In your case you'll have to use a Y extension to run the flaps - you can't control seven servos individually with a six-channel rig.

Hideho all,

Ok then, here's the bad news.
The only radio in the Futaba line that will utilize the quad flap feature is the 8 series, Super.

Ask me how I know....I bought the 120 US when I had the Super 7 and it wouldn't preform the crow function.

So I waited for 8 months until I found the sweetheart deal on a Super 8 tx only for 160.00 and then sold the Super 7 for 115.00 the next day online. Not a bad upgrade for 45.00.

Then, and only then did I begin assembly on the Ultra Stick.

Now that the Super 8 has been discontinued and replaced by the 9C, there are many good deals to be had on the 8 Super.
Oh, and for what it's worth, you need to buy Don Edbergs book "Getting the most out of your Super 8" too. The Futaba manual is absolutely worthless, and Don's book has more programming in it anyway.

The problems have been rectified on the Fut. 9 ch.

Sorry for the bad news, but that's the real deal.

The only other mfg who offers a easy program for the Ultra Stick is JR, that just happens to be sold by Horizon, too.

Well ,Hitec does too.

Gahhh. Is it safe to assume that you mean nothing *before* the 8U will handle that function, but that the 9 series will also do it since it is more modern than the 8?

Yup, affirmative I'm afraid.

Sorry Pal, but after I steamed up a bit, then calmed down it is a perfect excuse to upgrade.

Sad thing is your exchange, presently.

The good news is that the whole quad flap-crow- thing is just an absolute hoot to fly, I mean it.

Good luck,

I'm just about to start on the control horns on my H9 US 40. Hopefully, I will get it all finished this weekend. Does anyone have the programming guide for a 9TCAP to suit this specific plane? Would that book you mentioned be useful for a 9TCAP and where would you get your hands on a copy?

Regarding extensions, I used 12 inch on the ailerons and a 6 inch for the flaps....no -y-harness although I had thought about using one of these to make the programming easier.

I have the same setup and unfortunately the previous posts were correct. I personally wish I'd know that before I put the ailerons and flaps on. The 6X won't perform the crow but I've got the radio to activate the flaps using the airbrake switch. I have a Futaba 7 channel receiver so I had to place 1 and 6 with "Y" connectors but one needs to be a reversing "Y". I purchased a Miracle "Y" from MPI but I'm having trouble getting it to work correctly. I've emailed them and they seemed very responsive. With the "Y" connectors you won't need the long extensions. I have 6" extensions coming from the receiver to help unplug when disassembling the wing from the fuse but there is way too much excess with the extensions in the wing. Do some investigation into your radio setup before you place your control horns if you don't want to use a reversing "Y".

Good luck

If anyone has the Futaba 9C you can find an Ultra Stik setup proecedure on Futaba FAQs page on their website.

Denjones, I'm trying to understand exactly what you did. Is this correct?: You're using 4 wing servos. Aileron Y connector on channel 1 (with one servo reversed), Flap Y connector on channel 6 (with one servo reversed). In this setup you would get proportional flaps and conventional ailerons.

And, also in this case, you would use the airbrake switch to get the flaps down and the elevator up, while retaining control of the ailerons but without a crow function.

But, would this work?:
Plug the two aileron servos into seperate channels (1 and 6), then plug both flaps into channel 5 (landing gear) using a straight Y connector. This way you could use use the gear switch to drop the flaps (though only to one preset setting of course). And, you could use the flaperon function to get the ailerons to come up when you operate the proportional flaperon knob. <<This assumes that the flaperon function would allow you to raise both ailerons rather than lower them as the manual suggests (have not tested this)>>.

This way you would get crow as well as retain control of the ailerons, no?

I'm going to try that setup today! Maybe it will work for me. I've not been able to get the Miracle "Y" to work correctly but your setup may work. I'll give it a try and get back to you.

The method "fotta" describes should work. That is the way I had my UStik setup on my Hitec Eclipse. So for crow you would need to hit two switches. You would need to hit the gear switch to drop the flaps (mix in about 3-8% down elevator if possible) and then hit the switch or knob to move your flaperons up.

Also you can just flip one flap servo 180 degrees or use one futaba and one hitec servo as they rotate opposite. Since they are only flaps exact matching of throws and speed is not crucial. They need to close but not perfect.

Thanks for the heads up. Your suggestions about putting the flaps in channel 5 and setting up flapperons was just what I was looking for. I have set the airbrake to raise the ailerons and channel 5 switch to drop the flaps. I haven't flown this setup yet but it looks like it's going to work great.

Thanks.

Wait-No Need to upgrade. I have a jr 421ex(5 channel). I have quad flaps set up. You can't do crow or couple flaps to ailerons or all the other cool stuff, but I hooked flaps up to my gear switch, flip it and boom,flaps are down. It almost essential for flaps to keep landing speeds good. With flaps it lands slower than my trainer, without them you would almost certainly shear the gear off with the speed you would need to land. Hopefully this helps-remember, a 5 channel radio with yharness is all thats needed for flaps, but no crow, flaps to ailerons, ect.

I have never used flaps on my my US 40 during landing (you do not need them)...this plane can be a docile as a kitten on weed

Your right on that. Flaps are fun but not needed to land, the plane lands like a trainer.

I was unaware of that. Thanks, and a kitten on weed, haha beautiful choice of words.

When ch 5 is used for flaps and it is a one shot deal how much flap travel should be put in? I would guess at about 30%. Is this about right?

It depends on what you want to do. Flaps on take-off should be should be lower around 15-20%, flaps on landing around 25-40%. On low amounts the flaps create more lift than drag, on high amounts the opposite is true.
