Boomer, A fellow NTC3 racer on the RC Car Action site told me that the GPM pillow balls are for their aluminum arms only, that's why they don't fit (and probably why I won't get a refund). Oh well, he has the arms & I offered the pillow balls to him cheep. No sense in taking a total loss.
yes, the GPM pillow balls indeed does not fit the AE graphite Arm. The GPM pillow ball can only be used with the GPM metal Arm. they are shit quality.......
