Default Servo Torque for a fast .60 size

Hello Speed Demons,

I'm putting together a World Models Midget Mustang and am planning on powering it with an O.S. 91 FX 2-stroke. Since this will most likely be a very fast plane, does anyone have any recommendations on how strong the servos should be?

I'm asking this because I was planning on using Hitec 605's and a friend at the field (and postings on RCUniverse) have suggested that BB standard servos would be fine.

As a point of information, here are the stats on the plane ... http://www.theworldmodels.com/midget.htm

Default Midget Mustang....

I would prefer to use high torque, metal geared servos
for the ailerons, and elevator.

The Midget uses a torque rod set-up on the ailerons.
If all I had to use were Std. servos....I would modify
the wing and use two servos, and put a Std. servo on
each elevator (two).

Default servo torque

Ah Ha, the need for speed arises once again.

Try going to the www.multiplexrc.com web site. Under servos section (found off to the side) they have a formula that will allow you to determine the servo torque needed if you enter all the correct info. You'll find it surprising as we all usually tend to over compensate and over torque, but what the hey...peace of mind goes a long way.
