Me neither, in my years of running Tamiya plastic kits I do not believe I have ever had a self tapping screw loosen up.

So, I was running at the tennis courts last night, with all the pollen the little used back courts where I run were super dusty and slick. With that said it was tricky putting the power down on turn exits and I got one wrong and ended up collecting the car on a fence post and broke a rear arm, if the car was 6" further forward or aft it would have just hit the chain link fence. I ordered a new 51528 "B" parts but my question is when you order the 51528 do you get two trees or one? Looking at the Tamiya web site it looks like you get two.

Cheers,
Jim
