I just read a site on rc performance and saw people who would drill holes in the chassis and call them "mods". This sounds pretty stupid drilling holes in your rc car. But does it actually save weight or is it a wives tale.

I was going to say the exact same thing about the stress points. Some chassis designs you could drill 100 holes in them and not make a difference as long as the chassis is braced properly. Take the Arrma stuff for example. The centers of the honeycomb cells molded into the chassis could be drilled and you probably wouldn't notice too much more chassis flex.I've had chassis that were drilled and drilled a few of my own...it does take off some weight but only a few grams but on a really technical track that can put you on the podium.if your planning on drilling 1 you better know were your stress places are or you will be breaking chassis.
