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.

OK, Ill be sure to consider that.

----------------------------------------

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.

Good point. I have never experienced FM systems so I am not familiar with those sort of problems.

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.

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.

Ok, will try that. I dont have more servos, so I may have to order another.

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

Similar to what I posted awhile ago.... Low battery in the TX would be very similar to no TX at all. Plus, if you charged the battery and the spazzing stopped, you've already pin pointed the issue.

So go install your gear and have some fun!
