I have the following setup to go into a smalll model boat:
- Two channel HK 2.4 GHz tx/rx
- 5 x NiMH AAA rx pack
- A small (8g) VS-5 servo (steering)
- A standard VS-2A servo which has been converted for continuous rotation by removing the mechanical linkage between its position and its position sensing potentiometer. (throttle)
I have two questions:
- I can adjust the pot so that the VS-2A doesn't rotate at the centre point of its channel -- but this needs constant fiddling, and after running the servo forwards or backwards the setting seems to get lost. Should I remove the pot and replace it with a couple of resistors?
- When the pot isn't quite right, the VS-2A sits there 'chattering' -- making tiny motions back and forth, or intermittent motions in the same direction. While it does this the VS-5 also chatters, but when the VS-2A is running smoothly (because I've given it some throttle) the VS-5 is still. Why does this happen and is there anything I can do about it?
Thanks,
Tom
