Ah, it's great to read some feedback from you guys! I've raced alot of 5-minute heats since I have tightened my rear belt by one notch over factory setting (new system by the way... 18T center pulley, new belts and 37T F&R pulleys) and there is just normal wear on the teeth. Now that the tension is correct, I think that will last probably two months of racing (25-30 5-minute qualifiers/mains). I have a big race coming up this weekend and will replace both before our 4 quals and one main though.
So stefke likes the new pistons and Jimmy does not. I still have the originals in my shocks (middle-sized hole) but really should be using the smallest-holed pistons. Some day, some day, just lazy.
I have destroyed a rear upper arm mount but that was a crash last year and have not crashed hard enough yet (knock on wood, ha funny how you guys say
touch wood!

) to test the reinforced rear mount. I am still running the OEM front upper arm mount.
Recently had a Team Azarashi body painted and it should be sent back to me soon. I really hope there is enough room (height-wise) for my LRP TC Spec ESC (same as Nosram Evolution I believe).. it has the fan on top of the aluminum heat sink. Anywho, body looks like so...
Also need to get off my lazy ass this weekend before my big race and try the Kyosho ball cups with the OEM Tamiya rods. I posted before, my cups have not popped off too often but they do come off way too easily. Sounds like the other alternative is Losi cups and Hot Bodies ball studs.
Again, good readin' guys and keep posting! I always am excited to read new posts about 501Xs here and on 501X rctech thread (Electric Off-Road forum).
