Hi, I was looking to see if I could change the shell on a F7a NS, (like comes in the Thoroughbred set). I took the small black screws out of what looks to be a fuel tank. Then when I attempted to remove the phillips screws from the 4 posts, there is NO budging them. I finally gave up and reattached the black screws that hold the board in and now it doesn't run. The motor is running but the wheels aren't connecting. The only solution I can think of is taking the chassis out and reattaching what's come loose. Anyone else had problems with these screws??? I don't want to strip them but they won't budge.
Help!
