Use the right ones, or the carbon-fiber chassis can delaminate under stress.
Interesting. Wasn't it 100 degrees versus 82? I'm in the slow process of rebuilding of an RC12L and I can't bring myself to use the aluminum Philips screws. I miraculously found black steel flat-head 8-32 hex screws at my local hardware shop, and in several different lengths! Well, said steel screws seem to have the right angle for the front end, but for the rear pod the cones in the fiberglass seem to have a wider angle. It is as if they had actually countersunk the two parts with a different bit for each. Weird.
