I'm sure many of you have been in search of this: A light weight, high torque servo, to mount in the tail of the tail-heavy ARF's out there. And I'm using a light weight glow engine so that makes it even more tail heavy. I'm looking at HiTech/Futaba compatables and can only find one that meets my needs right now: The Futaba 3010S. It weighs in at 1.4 ounces, has 90 ounce-in of torque and .16 sec operation speed at 6 volts. But I found, like a few others, that the servo has some slop in the drive train. It also uses gobs of current.

Any other options out there? Most of the ones I see that have close to 100 ounce-in torque are in the 2 ounce weight class. I'd say 90-100 ounce-in is what I'm looking for. I'd like to use it on the ailerons and elevators of a 120 sized plane.

If you use two 1.4 ounce servos vs two 2 ounce servos in the tail, that equates to 1 ounce difference at the tail and 3 ounces in the nose (approx). So you have to add 3 more ounces of nose weight.

Actually your in luck, Hitec just released 3 new HB Digital Coreless servos, all under 2 ounces. They have a speed servo that has a speed of .08 with 120 or so ounces of torque, and a high torque servo that has a .13 speed and 174 ounces of torque!

Check out the Maxx Product MPI 890 servo
(100 oz/in, .08 sec, 1.57" x 0.77" x 1.37", 1.59 oz, 2 BB)


It is basically 1.6 oz, but has 100 in oz of torque and .08 transit time.... I am not sure if these numbers are on 4.8 or 6v.....Here are a couple of other by MPI, but they are a bit slower......use this link...... [link=http://www.maxxprod.com/mpi/mpi-15.html]MPI SERVOS[/link]
