reciever question
 

Just got tiger 2 arf instructions say 4 ch min and I have 6 ch also states I need y-harness for dual servos in wings question is is this just for a 4 cha. tx or can I plug other servo in different channel in rx?

RE: reciever question
 

I'm kinda new at this, but I think you want both aileron servos on the same channel, so the y- harness in needed. A single channel for both wing servos.

In any case, you want the ailerons to work on the same channel period, otherwise you would not be able to control the plane at all.

I am sure I will be corrected if I am wrong, but I'm pretty sure of this.

Good Luck!!

If you have a 6 channel radio a y harness is not necessary. Plug the second aileron into channel 6. If you have a computerized radio you can set up mixes like flaperons, etc. with the second aileron in channel 6. It will also allow you to program in differential.

RE: reciever question
 

I just reread the post and realized it is for a Tiger 2. I doubt you will be using mixes on that plane. So using a y harness is an option but not necessary.

RE: reciever question
 

See, I told you that I would be corrected.

But....as a newbie myself, I recommend using the y-harness and skipping the extra programming. I am still intimidated by my 6 channel Tx. I know it seems like you are wasting 2 channels, but only 4 are needed for that plane. I would try to keep things as simple as possible at first.

But...that's just me.

LOL...the only way to really learn is.....to screw up.

RE: reciever question
 

The y harness is easier, you just plug into your aileron channel and get servo extensions that will plug in from the y harness and reach your aileron servos. You just have to setup your servos so the ailerons move equally in opposite directions.

Most of us that fly 3D or aerobatics use a 2 aileron channel setup so we can use aileron diff, flapperons, spoilerons etc. But on a standard sport, scale or aerobatic plane a y harness is perfectly fine.

PS whatever you do be sure to secure your servo wiring connections with tape or something so they dont come unplugged and result in a crash.

RE: reciever question
 

You can only mix channels when you have a computer radio. If not you must use a y-harness. If you do, this mix is the first one you learn on the radio. Dennis

RE: reciever question
 

As a relative newbie myself, I remember the first plane I had with dual alieron servos (a Seagull Skywalker). I decided I would use a seperate channel for each servo, mainly because I didn't buy a "Y" harness and was over my budget already. It did take a little bit of fiddling to get set up and working, mainly working with the radio (a 9C). But once I had it figured out, (and it really wasn't all that hard, in retrospect) I think I was better off for it. Always pays to learn something, and a dual alieron setup is one of the easiest and least intimidating to figure out. Plus, it simplifies servo installation.

Now, if I can figure out how to get flaps and not airbrakes on the Twist I'll feel like I accomplished something...

Oh and I almost forgot.... I suggest the Ernst connector securing devices, you'll need a couple pieces of shrink wrap or tie wraps to finish the install, but once connected and installed, they're nearly fool proof and very light.

note to anyone
I am an older flier who is building a large scale gas powered cub. The mechanics of building is okay,
what I need help with is all the radio installations. Have read just about every thing on this subject
and still don't understand it fully. What I would to see is a complete diagram of an up scale system.
One that would have all the safety items that I could install. As you can tell I am relatively new to
the world of modeling.

Kittycat,

Have you bought your radio yet? If so most of them come with the drawing you’re looking for in the manual. It's really a pretty easy setup, the JR receivers have labels that tell you which servo plugs in which slot, the other brands might also but I don't have any experience with them. I'm not sure what type of safety items your referring to, the best thing I can think of would be a Hobbico Voltwatch (on all my planes) that tells you the status of your battery under load while the plane in on. It plugs into a spare channel on your receiver and has LED's to indicate battery voltage and will let you know if your battery is low or you have a servo with a problem draining your battery faster than it should. I don't have a scanner but can take a pic of the page in my manual with the radio layout if you like.

Knightmagic,

I would use separate channels for the ailerons and skip the Y harness if your radio has the ability to do it. It's an added cost (the y harness) and another component in the system to have a potential problem. Setting up the flaperons should be a pretty simple procedure, and the manual that came with your radio should fully explain it. Like the others have said it never hurts to learn something new. Isn't that why you buy a computer radio in the first place?

RE: reciever question
 

Yes my tx is computer a 6exa so I think I'll go with extensions and skip y-harness

thanks for the return,
I will be using futuba equipment which I haven't purchased as yet. thanks for the information.

One more note kittycat... Make sure you get a good instructor.... Unlike full scale, the cub is NOT a very good trainer plane... ;)

hi rusirius

thanks for your note. I am fully aware of the pitfalls. If I ever get this far! One thing I have it on floats
so it will be power on landing which should help.

Thanks,

kittycat
