They filter out the RF noise created by the motors. Without them you risk a serious crash caused by the interference. I would not fly the DF with even the smallest crack! They are too cheap to risk a crash by not using them.

thank you. i knew it had something to do with noise but never realised it could caurse interference. im not flying it anyway. the capacitor has completely snaped in half. Woops!

am thinking of convertingto brushless but i am researching it first to see if i can afford it and if i can get the parts cheaper. i am following the conversions posted on this forum and really excited about seeing some new vids.
thanks again.

i have done some research on capacitors and found the following info on the ones used on the DF:

100nF Ceramic Disc Capacitor

* For general purpose applications.
* 25Vdc max working voltage.
* 5mm lead pitch.
* High dielectric constant ceramic.
* -20% +80% standard tolerance.
* -25 deg +80 deg temperature rating.

As long as the caps are 0.01uF and greater than 12VDC (which is the maximum service voltage), your good to go.
