Radio Glitches

Hi Gang,

I think I've created a disaster. I gave my car its first clean with proper
nitro cleaner yesterday, I *thought* I was careful about keeping away from
the electronics ......

Now, the radio checks out fine, I start up the engine in the front yard,
everything fine. I run a couple of slow speed circles in the driveway, and
all is fine, so then I walk up to the end of our quite cul-de-sac street,
driving the car slowly next to me.

I get to the end of the street, do a couple of runs around my test track
(spray painted onto the road:-) and after a minute or two my car goes to
full throttle and full left lock on the steering! I have had a couple of
monumental crashes already (luckily not much damage so far - one tough
little car!). I'm sure its not transmitter range because the car has passed
strait between my legs a couple of times, still out of control!

I'm after any suggestions regarding radio glitching! Did I screw something
up by hosing down with nitro cleaner? I would have thought the radio would
be simply cactus all the time, not going haywire after a while. Could it be
interference? From some household appliance or gadget? What troubleshooting
steps should I take?

Help me here - I'm freaking out!

Keep it simple.

Reseat all of the connections. Something may have come loose.

Try new batteries.

Check all of the wires to make sure they haven't frayed somewhere.

If you have a graphite or metal chassis, put some insulation between
your wires (mainly the antenna) and the metal parts.

Keep it simple.
Put it in front of a heating register overnight, (or longer) to make sure
EVERYTHING is completely dried out.
It should be fine.

Might also open the servo cases a bit if needed.

Hi !

I have a tamiya XBG (43504) car too, and I recently had the same
problem.
The car was running on the car track for 10 minutes without any
problem and it sudenly went full throttle and left !

I hopefully didn't crash and I could catch the car before a fatal
issue.

Since this time, I only run on a car park near my home and all seems
ok, but I'm really afraid that it could appear again. I think it was
an interference problem, but I'm not sure... I changed the batteries,
examined all connections (no short circuit).
I have strange reactions when I touch the transmitter antenna or when
I touch metal part of the car (with the hand), but I find it's normal.

The next time I will try the car on this specific place (the car
track), I will use other crystal to be sure it was an interference.

try some wd-40. this stuff displaces moisture.
will help clean and quickly dry out electrical components/system.
is non conductive - no need to sweat when spraying on or around
electrical components.

I always try and keep a can handy

also works well after a good engine wash on my 1:1 Chrysler Sebring
I'll just remove the dist. cap, spray a bit on inside the cap, on and around
electrical components. snap it all back together, and Boom Viola Done!
