how does servo speed and torque affect handling? I'm putting togther a hanger 9 40 size "cessna" 63" wing span and 5-6 lbs. i have futaba 3001's and 3004's. the 3001 show .28 sec and 33oz torque, the 3004 show .23 sec and 44oz torque. so just wondering, do you want speed over torque or vice versa?

On something like a Cessna, you'll never notice a difference between those servos.

You get into 3D flying and you might start considering speed

Minn and W8ey are right on the money. At the level here in this forum (beginner's or intermediates) you will never notice the difference between the servos. To be honest with you, I doubt that many "experts" could tell the difference either.

A lot of people waste money on expensive servos they don't need. I suppose it make them feel better?

When should you use digital servos?I'm into 40 and 60 size sport planes and have always used standard BB servos.

Not all that many years ago a servo with 48 in. oz. was a pretty good servo and we used them on giant scale planes. Big stunt planes with large controls needed more power so two or more servos were used on one serface ganged together. Today we tend to go a bit over board on what is thought necessary for servo power. The new big digital servos are great but not always a must have item. I still use a lot of standard servos and on most planes that's all they need. Your servos are just fine for the use.

Do digital servos use less power?

Actually, digital servos use more power than analog servos. On an analog servo the servo moves to it's center point and then stays there using no power unless something pushes against it in that center position. But a digital servo moves to it's center point, but then sits there and continuallys "seeks" to stay in that center position regardless if anything is pushing against it. This uses more power from the batteries than the same sized analog servos would.

We got into 3D at the field in recent years and to have very large control movements with good authority and speed and still have extreme resolution at the center - you need digital

A analog just doesn't cut it in a true 3d situation

For sport flying the analogs are fine and that's all I use even in the planes that I jazz around a lot.

I also have some very high end analogs from JR, they work just fine. Yes digitsals use more power but hold better through there complete range. Batteries have also come a long way. Not long ago if you had a 1000 mah you were pumping power, I think today my smallest battery is 2500 and goes up to 4500. People thought you were nuts to be running a 6 volt too. It was considered over kill and looked down on. All that stuff about discharge rate. I think I only have two 4.8s left and in use. Everything just keeps changing so fast I can't keep up with it all.[&:]
