hey guys i was testing my sw2 last night and it was tweakin out like crazy......i was running 4ws with a rooster esc, and two 645mgs. i thought the problem could be that i was running 4ws.........so i took the rear steer off. so now im just running two channels with a tq3 and its still tweakiing out worse than it was....so then i tried the battery...nope not the battery. then i unpluged the esc from the reciver so it was just the one servo hooked up.. it didnt seem to tweak at all. then i pluged the esc/motor back into the reciver and the minuite i did that it started tweakin. i think i have narrowed it down to either the motor or the esc..what do you guys think????????

Do You have a rx pack (receiver pack) ?

If you have one handy plug that into your B/C slot on your receiver.

And see what happens it may be your number of amps your BEC has.

snook · 12-12-2006, 09:08 AM

no im not running an rx pack so i guess i will try that..thanks

What crystals are you running?

racerx · 12-12-2006, 09:47 AM

I had the same thing happen when I scraped a capacitor off on the rocks, Make sure they are all attached like they should be.

I had a bad 645mg make my truck do what you are describing. I could run the truck about 5 min. and the steering would start glitching, then get worse and at about 7 min. The whole thing would start glitching, rear servo, esc and all.

I asked about the crystals because i bought 4 sets of cheap 40 mhz fm crystals to run all my clods on one radio, and they all glitched, i just swapped back the original acoms crystals on my radio and receiver and no more glitching, i tried the acoms receiver crystal with their own different receiver on all the other three rigs and no glitching, at least that was my problem.

snook · 12-12-2006, 02:03 PM

well im just running the stock crystals when i bought my tq3 of ebay.......
also i probly should have mentioned this before...im not running any capacitors on my 55 lathe.....do you think thats my prob

Moondust1950 · 12-12-2006, 02:06 PM

Yes

snook · 12-12-2006, 02:21 PM

ok.....one more question...do you know what size capacitators i should get for a 55t lathe and a novak rooster....i dont have any so im gona have to go to radio shack.

ravencrawler154 · 12-12-2006, 03:50 PM

.1uF <---thats micro farad

Moondust1950 · 12-12-2006, 04:33 PM

Have you used them before?

There should be three in your ESC box

EeePee · 12-12-2006, 04:33 PM

I've never bothered with capacitors.

And exactly what the hell is tweaking?

snook · 12-12-2006, 04:44 PM

just whenever i turn the truck on .....the steering just starts tweaking and the truck just has quick jults of movement back and forth..:-(

Moondust1950 · 12-12-2006, 04:50 PM

Perhaps its your receiver.

Is your antenna broke on your transmitter?

EeePee · 12-12-2006, 04:51 PM

Try unplugging the servo and see if it does it. Narrow it down more.

snook · 12-12-2006, 05:08 PM

ya i unplugged the servo and it does it..so its either the esc or the reciver.

snook · 12-12-2006, 05:12 PM

the wire on the reciver from the antenna started to unravel from the plastic...so i put some heat shrink on it....im thinken its narrowing down to the reciver..but i put my 4 channel radio in it and it still tweaked so i still have no idea.
