Hi, I'm about to start building my second plane a Phoenix Tucano. It has seperate aileron servos. Which is the best way to go Y Leads or a seperate channel for each aileron? What are the pros and cons for each way? I have a JR 2610 6 channel radio so I will 2 spare channels.

cheers

I use the "y" harness and never had any problems with it. I have them on all my planes that have double aileron servos.

It depends on what you want them to do. Simple ailerons a Y-cord is fine. Flaperons need 2 channels. Aileron differential needs 2 channels or it can be done by positioning the servo wheels/arms just right, but this limits travel in one direction usually.

G'day Mate,
You have invested in a good 6 channel computer radio, USE IT, select flapperon wing, plug your right aileron servo into "ail" channel, & your left aileron servo into "aux1", & bingo it is done.
You will need to "inhibit" the flap switch.
You have to set servo direction, travel, & subtrim, but you can also fine tune it as required.
Read your manual for these settings.
IMHO use Y harness if you are lazy.

y harness is simplicity

The biggest advantage to using two channels is being able to use sub-trim to center each servo independantly. Beyond that, you can use the ability to program in differential to help the plane handle better. You can put in differential using a Y-harness as well by setting up the aileron horns slightly offset, but you can't fine-tune it like you can with a computer radio and 2 channels. That said, for most guys most of the time, it's fine.

For reference, I'm just about flight-ready with a Mosquito twin-engine plane. I have a 9 channel radio. I'm using a y-harness on ailerons, but duel elevator servos, duel throttle servos and duel flap servos all on their own channel. Because having that electronic fine-tuning is more important to me on those 3 channels than on ailerons.

I once tried to do flaperons on my Twist but then I had no athority in the ailerons so I quickly swiched back to a Y. Just mechanicly set each servo to 0 then use radio to trim, thats the easiest way.

Thanks for all the help. I need to buy servo extension leads anyway so I'll give using 2 channels a go. If I can't get that to work I'll get a Y lead.

Shane. I have several aircraft using the dual aileron configuration using two separate channels. It's easy to set up and easy to get to that program in your radio. Allan is right. Use the capabilities of your transmitter. I have one plane with Y connector for dual aileron config but it is just that. Dual ailerons with no capability to do anything at all with them. My other planes have flaps, and differential.

I also use a 6 volt battery on my Rx's that provide you with more servo speed and power. My batteries are all 1200 mah or greater, by the way, so I don't worry much about running them low in flight.. I check them before flights and recharge when necessary. I only mention that because if you are going with more than 4 servo's as on planes with a single servo on the ailerons, you may find it more comforting to have a slightly higher capacity battery with the higher voltatge.
