Pulsing acceleration
 

I just bought my first XMOD (black civic) and played around with in a bit in the parking lot. Everything seems to work fine except when it gets more than 5 feet away from me the acceleration seems to pulse... as if I was rapidly pressing and releasing the throttle. It still accelerates to speed but it's like the "little driver" inside is have a leg seizure with his gas pedal foot.

Anyone have this problem?

(BTW, the terminal connecting to the antenna was covered with gucky electronic flux like material... I scraped it off for a cleaner contact, but maybe I didn't scrape it well enough?)

You could either be getting interference from an outside source (especially since it's in a parking lot), or your signal transmission may not be coming through clearly enough. This could be because the batteries are going dead, or there's simply some electrical problem. I've never heard of flux being on the antenna..that could be a rather bad sign. Not that it would directly hurt anything, but it could be defective or something.

what is flux? the core of the solder that RS used?

Yes, you are correct.

I reccomend you clean the antenna connector. That should help.
