My group is planning on using a servo identical to the one in the KoP, along with a Hitec Laser 6 radio control system (for model airplanes). We need the angle of rotation to be greater than 60 degrees. Is there a simple way of doing this?
Ok, but how do you get the full 300 degrees of rotation using a hobby shop remote control system? Right now I’m only seeing 60 and adjusting the trims only made the rotation smaller.
Indie,
As I remember, the servo is about 60 degrees. You need to couple another gear or gearset to get the angle you require. Mechanical linkage works OK too!
Or you could take a file and file off the nub that stops the servo and make it turn 360, basicly making it a motor. Just pop off the top and there is a small tab that conects to the pot I believe is in there and makes it stop. I dont have my modified ones near by to say forsure exactly what to do. But it goes something like that.
You also might want to replace the pot with a resistor (preferably one that matches the mean resistance of the pot) to prevent drift. However, this will give you a motor with a built-in speed controller, not a servo which can go to a specific position.
