Hi Everyone,

Well, i bought Mark's 88" Yak today!

Now i would like to have some advice on what servo's to put in it

Somebody told the Savox 1256mg's are good but i'm wondering if they might be a bit slow...

HELP!

Brian

Sandy: your servos are not up to snuff...why you ask? Because one of the other guys said so.  lol.

As an "other guy" I'll say your servo's are up to snuff Sandy.
Now the pilot on the other hand.............

on the other hand is 4 fingers and a thumb.....

Brian, somewhere I read an article by Glizellis  (yes gang I CAN and DO read) that with the new radios, transit time is far faster than anything we mortal humans can initiate. What holds servo movement up is not the servo itself,  but the servo waiting to find out where the thumb on the stick is moving.
As you said, the instructions tell you the torque required, and any good digital servo is already faster than you can move....
With an airplane I doubt you'll notice the difference between a $100 servo and a $300 servo... and here I hang my head waiting for the torrent of abuse that comment will elicit 

Hi Guys
Some really good comments here.
Servos are very important . You don,t have to have the best on the market and you don,t want to buy the cheapest.
Year ago I kept breaking my tramsmitter Sticks .I use to get a lot of comments that I was too hard on my gear. It was a long time realizing that I couldn,t make the plane due what I wanted.
I have some servos in the 60 dollar range. They are good,but when you get a few hundred flights on them the centering is gone and a lot of slop in them.
I don,t fly the big stuff yet, I keep around 80 " Span and I am using about 130oz  torque servos.I think speed of the servo depends on your fingers and how you want to fly

A well trimed aircraft is just as important as a good set of servos. You also have to realized that some of these servos are gettig up there in weight 2 to 3 oz per unit.I know that doesn,t matter to alot, but when you start adding weight to a plane it will not handle like a lighter plane.Light is good heavy is bad.  If you want to find out how good your system responds due knife edge flight both ways.
Then due a knife edge loop.That will will tell you if you got enough speed and torque.Make sure your knees are not shaking when you do this. Don,t ask me how I know this.

There are always different ways to do things in the hobby.
There is always something new to learn and see.
The most important thing to remember is to have fun whatever you do and come to the field and ask questions
from the guys .

Hi Brian
I know that this is more expensive but I am a Futaba Man.This is probably what I will go with in my 50cc setup.They are 149 Dollars at Tower Hobbies.If you buy more than 1, you get a small reduction.
I would check with John at Martime Hobbies before ordering online.

This is the Futaba BLS351 Brushless Digital High Torque Metal Gear Servo.
                 Designed for any RC hobby application.

          This servo can produce high-current draw from your batteries.
          If using NiMH or LiPo batteries, make sure they are capable
                         of delivering sufficient amps.

Features: Equipped with a Brushless motor that lasts longer and operates at a
            lower temperature than Brushed motors
          Samarium Cobalt magnets and dual ball bearings
          30% faster response times, smoother operation.
          Same power consumption and centering as Digital servos equipped with
          Brushed motors
          Standard size
          Metal gears
          One-year warranty

includes: Futaba BLS351 Brushless Digital Servo with universal
            connector, 0.83" (21mm) diameter round horn pre-mounted
          1.7" (44mm) long 3-point horn
          Servo mounting hardware

Requires: Installing in model and plugging into receiver

Spec:    Torque: 4.8V: 173 oz-in, 6.0V: 217 oz-in
          Speed: 4.8V: 0.16 sec, 6.0V 0.13 sec
          Dimensions: 1.6 x 0.8 x 1.5" (40 x 20 x 37mm)
          Weight: 2.2 oz (63g)

If you look at the listing on Tower they also have Ditigal Servos.
I believe the 251 is 119 Dollars.
You can bring up  the servos on Tower Hobbies and click on Teck notes to get the information about the servo and  all the prices.
