A servo for each a ron is a bit heaver , but a lot less slop, A LOT.
This is simply not true when installed properly.
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.

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-servooption is thebest 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 knowI 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.
