RE: Using Mic servo for St. servo
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....
