mine was a c-8, and the board was a rev. 5a, not rev. 5. i guess they are trying to get trickier with these newer boards - i'm glad my guess was right!

edit - i tried out a few pen tips and found one that is perfect. now i have to buy a 2nd to make a pair. there is no need to dremel or poke a hole in the car, since the shape of the body gives a natural "U"-shaped space inbetween the wheels and the chassis below the body.

the body also has a pinhole on the top to let the antenna out, so i figured that sticking the other end of the antenna back in the hole would create one loop - no loss of range! also the loop is springy and firm, so now when i run the Mach below the doorjam the loop catches for a sec, making the Mach do a wheelie - fun!

one observation - when the battery is almost out the wheels will turn right, but not left. i guess there is a natural resistance to the left, which explains why i have my steering trim turned to the left to make the Mach go straight, and when i put it reverse it reverses in a curve. in fact, on the hardwood i give it hard reverse to make the mach do a 180 and head back!
