With the cost of a servo, and the capabilities of even a modest radio, I see no reason whatsoever NOT to put one servo on each aileron.

A servo for each a ron is a bit heaver , but a lot less slop, A LOT.

And... nobody is required to approach an aileron install in any other manner than safely. Belcranks work just fine, and without slop. So does the aileron rod method. Both of these can use 2 servos as well, btw, and you don't have to add extra weight outboard in the wing. From this knowledge, belcranks and aileron rods make more sense, actually.

The bell crank method works great. Allthough to prevent blow back, and gear striping I would use a higher torque metal gear servo. It never hurts to over do it.

This is simply not true when installed properly.

RE: Two servo ailerons
wow, lots of good discussion here, things I've never thought about. I was about to rip out a good looking bell crank set up on a 1/6 Pica Waco for two outboard aileron servos but now I don't know. Only thing is they are old and plastic. If I can replace the plastic with something like above I may try them with a stronger servo or two. Thanks for all the discussion.

I would have to agree that a bellcrank can be set up to be very efficient. I had one in a Don Muddiman ''Flying Machine'' and used a single servo with a ''line drive'' servo horn that was sweet. It worked really well, and doesn't move the aileron torque rod up or down with the rotation of the servo horn. I have also used single servo method many times with good results. But as many others have mentioned, I think the dual-servo option is the best for flexability, ease of installation, almost idiot-proof slop reduction, and overall is just the best option available in my opinion. And redundancy is a good thing, I know I had no problem landing my giant super sportster when one aileron horn broke last year. With one aileron working, I hardly noticed (except for the aileron flutter on one side!) But when you get down to it, they all work, and can all work perfectly fine for a plane like the chipmunk.

Gene, sit down, this is going to hurt. Neither the cub or the Chipmunk is avaiable at tower any longer on the Tower site. In fact just like the Lanier line, the Goldberg line isgone. If you do a brand search, not a single plane shows under Goldberg, just a few misc parts and not many of them. The Goldberg site is still up but not the old one. They state thatthey don't sell direct anylonger, go to your LHS. I'm guessing if Tower doesn't sell it, it's not avaiale unless it is "Old Stock" at a LHS.

Yes/no. Cg was bought out by Lanier then Lanier was bought out by great planes. GP pretty much killed off most of the kits but the Chip and Cub is still alive and well.

does CG even sell anything any more ?

RE: Two servo ailerons
In reality either system will work. You can use small light weight digital servos and not gain any weight. Bellcranks work and are time proven, but generally can't be adjusted easily once the covering is on. I owned this exact plane. If you use bellcranks I recommend using ball links for smooth non wear durability. Best of luck! Mike

RE: Two servo ailerons
I am really impressed with all of the great ideas! I ordered the Chipmunk last weekend from Tower and I feel like a young kid just before Christmas!<div>As suggested, I am going to buy a 4 channel arf trainer and get comfortable with it before I take the Chipmunk up. It will probably take allot longer to build than I am thinking so it probably wont build up too much dust.</div><div>
</div><div>One more question on the aileron servos...</div><div>I like the idea, ease and redundancy of two servos but if I mount them out in the wing to avoid a long control arm, that seems sort of anti aerobatic, if I mount them next to each other in the wing root, it still has two long control arms. Am I over thinking this?</div><div>
</div><div>Thanks again,</div><div>Mike</div>

Another point that I have not seen in this thread is that if your transmitter has flaperon mixing you are going to
need dual servos if you wish to use that function.
Happy flying, Oscar

You'd be hard pressed to find any kind of aerobatic aircraft manufactured today without that setup.

RE: Two servo ailerons
Anti aerobatic might be a little overkill! And now thinking about it, an extra 37 grams out in the wings while they are under load is probably nothing. <div>The funny thing is, I am getting all serious about this airplane and sweating each detail and I have never even flown a four channel plane much less the aerobatics that I imagine I will be doing with it one day!!!</div>
