You should be able to find a kit of these small screwdrivers (called Jeweler's screwdrivers) at Radio Shack. They come in a little plastic case and consist of about 4 - 5 each of flat blade and "X" point (or Phillips head) types. Shouldn't cost more than a couple of dollars.

Try radio shack they have some mighty small screwdriver sets phillips and straight. They had the one that would fit the Walkera 4#3B rotor blade attachment and that is almost microscopic !!!!!

One thing I've found about those "Jeweler's Screwdrivers" is that the real cheap ones are made in China and the quality isn't all that great. The tips twist, break, and the "X" point ones wear down quickly and become useless.
However, I found this one (pictured) at my local hardware store which is a very fine quality with 4 interchangeable tips. Cost was around $3.50, I think, and well worth it. Bill |

Bill ---------------------------------------- I hooked up the servos. They have good throws when they are at the second-closest hole to the surface. Whats wierd is these servos started randomly spazzing, without any input at all from me. At first I was hearing a bit of a grinding noise for, like, 2 seconds after the servos returned to neutral, but now they just spazz. Does anyone know what is causing this. I have no flying fields near me that may be interfiering.:<: Thanks, PA |
A little bit of 'coasting' is normal sometimes. Anything more and it could be a control surface or linkage is binding up. Do you have pictures?
|
in my experience, the "spazzing" has always been caused by the wrong channel selected on my TX, or not turning my tx on at all.

With my Spektrum RX's, all of the channels (except throttle) keep their last commanded position when the TX is turned off. Even when the TX is on, the only time I get servo twitching is a bound up control surface... or in one case a bad servo. |
Can I upload a video, without youtube?
EDIT: Apparently not. I will take photos. |

The pictures dissapeared.
EDIT: Oh there they are again after I just made the next post. |

OK. The first pic is the servos in normal position with everything off.
The second pic is the linkages, still no spazzing. The rest are the "suicidal" looking servos. They seem to twist as far as they possibly can. |
Hmmmm.....
Did you rotate the servo arms by hand with the power off to 'center' them? |
I think I may have pushed the control suface up, and that may have happened. Would that have destroyed the servo?
|
If you force a servo hard enough you can strip the gears.
Personally, I would disconnect the linkage, remove the servo's from the plane and test them. You can simply rest them on a table top or something. If they still behave erratically then I would start looking at your connections, the RX and perhaps try a different servo. |

It seems that the problem was that my tx battery was very low. Is this possible?
No spazzing now that I have charged it. EDIT: I recieved the motor, battery, ESC, props, prop saver, and connectors Wednesday. HURC supplied it in perfect condition. |
So, is it possible that the servos were spazzing because of the low tx battery?
Looking for an answer:D |

So go install your gear and have some fun! |
