How to Adjust Control Throw for RC Airplanes
How to Adjust Control Throw for RC Airplanes
In this video I will go over how to adjust the control throw on your RC model airplane by understanding the geometry of where to place the control pushrod on either the servo control arm or the control surface control arm.
This technique is useful basic knowledge can be employed for various ARF models that need additional control throw, even if the computer radio is at 100%.
I also demonstrate as an example how I used this technique to increase the elevator control throw on my FMS Corsair RC model airplane.

Other considerations are the forces brought on by the length of the lever arm, (horns and servo arms). Think of an air-load of a control surface pushing back against the servo when a short control horn is used. When a longer control horn (lever) is used at the surface, the servo is given mechanical advantage over that force but at a sacrifice of the amount of throw. Yes, I've stalled a few servos over the years.

When you move the pushrod closer to the control surface, you're inviting the surface to flutter. Shortening the control horn gives the surface more leverage over the pushrod and increases the forces on it. When I need more throw, I use a longer servo arm or I increase the travel in my Spektrum transmitter to 125%. If I have too much control surface throw, I make sure the pushrod is in the outer hole on the control horn and then move the pushrod in on the servo arm. I try to avoid setting the servo travel in my transmitter to less than 100%. My dual rates are typically between 75% (low rates) and 100% (high rates). On 3D planes with large control surfaces, my dual rates will be between 60% (low rates) and 125% (3D rates).

Great points, thanks! Tim
Tim, not really pertinent to this video, but, I just received my SKYID module from Spectrum. Will install it in my "beater" airplane for flight tests.

Ted: Very useful update, thanks for sharing! Tim
Tim I have a question about remote ID I really would appreciate an answer I was wondering how do I connect a remote ID module to a DJI Phantom Advanced professional when there's no power available on the drone? Do I connect it to the transmitter? Thank you very much for your consideration and your time I really would like to have an answer Mike

Mike: It will depend on the remote ID module. The module needs power, obviously. For the Spektrum SkyID you can plug it into an open channel on the receiver if you have one. I think the BATT plug will work as well. Or, you can use a stand-along battery for the RID module.The module is in the drone, so no way to use the transmitter. Spektrum would have further details, in this case. Tim
