On Tower, it says the Tiger 60 needs 2 6" Extensions and a Y-harness. What length does the Y-harness need to be? I know alot of people have this plane. Will two of http://www3.towerhobbies.com/cgi-bin...0&I=LXL287&P=K and one http://www3.towerhobbies.com/cgi-bin...0&I=LXL307&P=K be long enough?

Yup

The Y harness needs to be long enough to reach easily when putting your wing on at the field.
The one you have listed will be more than enough for most airplanes, in fact you will find you will have to tie some of it back.

If your radio transmitter will support it (5 channel or more) you would be happer and have more control over the plane's trim if you use individual servo leads rather than a "y", plus you can make the Tiger do a lot of cool aerobatic stuf like "crowing", spoilers, etc. While you should always try to mechanically get your trim as close as possable, individual servo adjustment makes it quick and easy to fine tune. BTW I have had 2 tiger 60's... one a taildragger with an OS 91 surpass II and one with trike gear and a MVVS .61 piped 2-stroke and they were some of my favorite airframes ever! But to answer your question, the length will be fine. One other hint... I put a piece of ply diaginally across the fusalage directly under the wing shoulder mounts, with 2 holes drilled in it with the same spacing, etc. as the dowells in the wing. Then I could plug the wing in them while I connected the servo leads with both hands.
PM me if you have any questions...I don't hold myself out as an expert but I am familar with that plane.

You can also use two separate RX channels if you wish, and if your transmitter will handle the mix (computer radio).

On my Tiger 60, I used the Airtronics Y connector which was a tad long, but the combination of the length of the fixed wires on the servo and the 6" extensions, you will have plenty of length with any of the Y connectors you choose. As Missileman said, one may be a tad long, but that won't matter much.

Make sure you secure the connection of the servo wire to the extension so it does not come apart in flight. That can certainly ruin your whole day. Use something like this (the one shown is for Futaba, but there are ones for JR, Airtronics and so on).

I just finished my Tiger 60 Kit. The extensions you list are o.k. You don't need a 21in. Y-Harness.. WOW. I used a 6 in. Harness and had to push some back into the wing. 6" Y is plenty. Bill M.

Can I use just the 21in Y-harness with no other extensions? I figure fewer connectors have a better chance of not coming apart.

Then again, im gonna get a Futaba 7C 2.4 ghz radio, so i can use two channels. hmmm Now im wondering what length extensions will work with this setup. I guess if 6" extensions and 6" Y-harness work, then a 12" extension for each servo with work. Is this safe to assume?

The way I do most of my planes, not all but most. I install the Y harness in the fuselage plugged into the receiver and the extensions come out of the wing by a few inches. At the field I plug the extensions into the Y harness when installing the wing.
You need a connection from your receiver unless you want to mess with trying to plug directly into it every time, which can be a real hastle.

How will you connect the Y to your servo? The connection will be inside the wing somewhere and neither lead is long enough to get to an opening. An extension can be connected then fished through but a Y harness has to go to both ends of the wing.

oh ok. Thanks for the help. Im used to my Alpha where the servo lead is right there, i guess ur right about the servo lead being in the wing.

What's interesting about this is that no matter what leads to where, if the ailerons are set up correctly, they will work correctly no matter what leads get hooked up to what.. left to left.. or left to right.. doesn't matter. At first, this is a bit confusing, but a little thought tells you that the signal leads are common.. (as are the power leads) so it doesn't know nor care what it's hooked up to as long as it's hooked up to aileron servo leads.

I use 2, 8" extensions to my wing servos and 2, 6" extensions from my reciever. Plenty of room for plug in.
I also set the plane up and do all my Adjustments and while dissasembling the plane the first time
I use some white paint on 1 of the connectors so I know which extension goes where.

Missleman, The length from the servo wire hole to the servo opening is only 5", with a 21" Y harness he
could fish the harness through the servo wire holes in the wing and out of the servo opening, plug everything
together and leave all the excess wire in the wing. I agree with you and would add a small extension from the RX
so you don't have to keep plugging directly to the RX everytime.

CGRetired,
How do you like your TIGER 120? I haven't seen one fly but once. It's on my list if I ever finish the planes already waiting in my shop!
Mike

Cool, same deal as my CAP 580 then. If that is the case you will only need 1 extension to go on the receiver and the Y harness.

Hi Mike.

Well, it flys great, typical Tiger. As you may have read, (maybe you have not, but I've posted it in a few different places here on RCU) the only heartburn I had with it is that it took over a pound of noseweight (lead strips) in the nose to make the CG. A friend has one with an OS 1.60 FX and he needed quite a bit of noseweight to make the CG. Mine has the OS 1.20 AX and needed more wieght.

It's a solid plane, I did not use the tail braces to hold the vert/hor stabs in place, they do just fine as they are, and this would have added even more tail weight which would have needed more nose weight.. so I just left the hardware off. And at about a 1 - 4 ratio (1 ounce in the rear needs 4 ounces up front to counter), I didn't need any more up there.

But, as I said, it flys great. Very deliberate, and straight, I must add. It's fun to fly, by the way. Very much a Tiger, if you've flown any of the other Goldberg Tigers (Tiger II and Tiger 60) which I have. When I did my first aileron roll with it, well, I was sort of used to a roll rate of perhaps 2 seconds. Well, a normal roll rate with this big guy is more like 6 seconds. Slow and deliberate.. and straight!!

It lands like a very large, powered kite.. "floats like a butterfly".

I just plug the single port of the Y into the RX and leave it there, then have the V part of the Y available to plug the servo extensions into.
