Servo Torque
 

What is the minimum torque required on an electric heli servo? There are a few 9 gram and 18 gram micro servos on ebay with the following specs

9 gram servo spec:
LENGTH : 22.0 mm / 0.86 in
WIDTH : 11.2 mm / 0.44 in
HEIGHT : 22.0 mm / 0.86 in
TORQUE : 0.8 kg-cm / 11 oz-in @ 4.8v
SPEED : 0.11 sec / 60 deg
WEIGHT : 9.0 gm / 0.31 oz
VOLTAGE : 4.8v - 6.0v


18 gram servo spec:
size 28.4 x 13.2 x 35.1
speed 0.1 sec / 60 deg
torque 2.0/27.8 (4.8 V) 2.2/30.6 (6.0 V)


I just wanna make sure before I commit.

thanks

Rebar,
This is going to depend largely on the heli. Please ask your heli manufacturer what THEY require for your bird to ensure you have what you need, or tell us where what hte bird is and we'll see if folks here can help. Your question might get better answered in that case, however, in the heli forum.
