Having just bought a bit-char G recently that had poor range, I opened up the transmitter – and the crippled capacitor was not there (just like some of the others).
However, after some poking around the web, I learnt that the cap was on the car instead!
I’ve added a page to my site with fairly complete info about cripple capacitors, with lots of photos and links. It has details on how to deal with new batches of cars where the cripple cap is found on the *car* instead of the transmitter:
very nice job, but i have taken a look, both inside the controllers and the cars and i’m not prepared to damage my bit whilst incresing the range, it should be done by the professionals, not any novices, take mod chips for example, they are so cheap to buy, but so expensive to install.
