I'm putting to gether an RF Hangar 9 mustang .46 size. It's recommended to use two St. servo for aileron. Is it Ok to use two Micro servo instead of standard servo for aileron to save weight?

In one word, NO. Try saving weight somewhere else.

Besides, saving weight is fine if you're flying 3D, but warbirds were designed to carry bombs and machine guns. Plus the fact that a 46 engine in a 46 size RC plane is like having twice the scale power anyway.

Don't EVEN worry about saving weight!

Don't do it.

Actually you CAN use MINI servos instead of Standard Servos.

He may be confusing Mini with Micro servos. The distinction is not obvious to newbies.

Many Mini servos have torque ratings that equal or exceed standard servos.


If he opts for higher torque Mini servos he'll be fine.

I've done it on many 40-75 size planes w/o problems....

Hi!
Standard servos weigh around 40-50g. Could be replaced by mini servos without problems (i.e Hs 225) that weigh 22g.
Sawing 50g on a small .40 plane is much!
But then I'm a pylon racer

Torque rating should not be the only consideration here, as one should also take in to account the robustness required in the servo for the type model or application it is going to be used in.
