Interesting 601 related

[Russ McC]

Well last summer I had a mild crash with one of my Ions and the 601 sensor got damaged, I half ass glued it back together and glued a tie rap on and around it, the sensor worked fine on the bench. After that it had a tail twitch so I removed the tie wrap and the twitch went away. When the twitch came back a month or so ago I replaced the sensor and the twitch got worse if any thing. I started investigating and found a lower main shaft bearing that was toast, replaced it with no affect on the tail problem. I then removed the UBEC and installed a battery and switch, no affect. Then I tried a different servo, still nothing. I then installed a different auto sprag assembly, no affect. Well when I glued the damaged sensor back together some glue joined the sensor case to the shield plate and when I replaced the sensor I had none of the correct tape so I used scotch brand white foam tape, this proved to be the problem! When I took the sensor off my other Ion, bracket, tape and all and installed it the problem was fixed. I then put the scotch taped sensor on the other Ion and the twitch followed that sensor. I then removed the sensor from the shield plate and re attached it using some other piece of die cut real spongy gyro tape I had around and problem solved. I have mounted these sensors very rigid in the pas with no problem, I suspect it was not to ridged but that it was not isolated from RF or static coming from the machine through the tape to the sensor.

I thought I would share this because it seems that we Ion pilots have had a higher then normal amount of gyro (601) twitching and have found a number of causes. This is just one moor thing to watch out for :!:

I've also had excellent results with the Kyosho Zeal gyro tape...

Hmmm...
Russ that is interesting.
I use that 3M stuff all the time.
I just mounted the 502 sensor in the Ion with it.
So far no glitches, but have only done one realy quick flight.
I will watch out for it....

I would not be surprised if it works just fine, I have had it work for my in the past. It amazes my how some things that seem so insignificant can cause huge radio problems and at times I have found major problems that should cause the thing to lock out and the radio doesn’t care. It’s all magic to me :dontknow

Interesting. Have you tried the clear 3M stuff? It is a lot liek the Zeal but not nearly as soft. I have one machine with a little twtch is why I am asking. Tsame guro/sensor did not twitch on teh R90 it used to be on, only now that I moved it.

Thanks for the info!! :) I will change tape and see what happens.

I have not seen this clear tape. Where do you get this? Are you using this clear tape on you gyro now that is twitching? Let us know what comes of this.
