Tower Pro Brushless Outrunners Improved!
Just got a new batch of 2408-21, 2409-12, and 2409-18 motors (BP21, 12T, 18T) from aero-nuts.com and they have improved the motors a bit. There are now two set screws to hold the motor to it's metal mounting plate as well as two set screws on the top of the bell to hold the prop shaft to the bell, replacing the single nut that was on them before. The motor shaft hole's metal near where it mounts to the metal mounting plate also looks like it has been beefed up. These motors look much more stronger now. I'd put a bit of nail polish on the head of the set screws to prevent them from vibrating loose as I just found out that, despite how tight I made them, they like to still unscrew.
