RC Servo Torque vs Force and the Importance of Mechanical Advantage 

I have no plan to stop.

Hey Martin, thanks for the comment! Cheers from Canada!

Very good point! I was playing around with the radio and setup over the weekend looking at the difference in resolution of a micro size servo when EPA is brought to 50%. This will be in a future video.

Hey Thanks ETAI106! I was just looking for the true unit of force in the SI(metric) system as well as the unit of mass for the imperial system.(not a term that is heard often) If the metric mass unit is used as a force I would prefer it to be written as you described kgf. However, it is still awkward. It's uncommon to see torque measured in terms of kg for most mainstream applications.

@@RCexplained Im at the automotive industry.. All the technical literture from cars manufacturers ive seen, they do use Nm.. Except the American ones... I live in Israel, here as well we use Nm at almost all application ive run into. lbf or oz are very very rare to me..

Newtons are not kilograms. [N] = [kg * m / s^2], or mass * acceleration as in F = m * a. Newton is the SI unit of force. Torque = force * level arm, or τ = F * r, so in SI units [N] * [m], or [Nm] (Newton-meters) Servo specifications in the rest of the world commonly use [Ncm] (Newton-centimeters). If divided by 1g (Earth's gravitational acceleration of 9.81 [m/s^2]) your basically calculating F/a = m, so the resulting unit for this way of specifying servo "torque" (not really) is [kg*cm]. This is also a common specification. (The weight of 1 kg under Earth's gravitation is sometimes called kilogram-force or kgf but this is not standard SI.) So if a spec sheet says 9.81 Ncm or 1 kg*cm then you can hang a 1 kg weight from a 1cm long horizontal servo arm and the servo should be able to hold it.

Hey Isogen. Thanks for the comment. I'm struggling a bit with equipment, not just with lighting. Serious lighting is on the way for next WB video. Jason from EE is brilliant!

Hey Polish guy, thanks for the excellent tips and the comment!

Hello, what points on the topic of Gyros would you like to have coverd?

@@RCexplained topics : benefits of gyros ,proper setup and installation ,adjusting gain, is the gyro in the right orientation things like that

Hi Remko, I've never seen a setup with 2 control rods being used other than an outboard boat engine. Dual rods were used here for stiffness of the rods as the weight of the outboard is quite significant. Comparing pull pull vs push pull, my preference is push pull using one solid rod.

Always could use more torque!
