Castle Creations motor sale:
1518 = 60$
1520 = 65$
1717 = 70$
These used to cost around 150-200$, but Castle are clearing them out. These motors weren't sold as combos with an ESC, and that is the reason why they haven't sold as well as 1515 for example, which was sold with an ESC and RTR kits, and is still at a high price.
These are some of the most powerful and most efficient 1/8 motors around. For the price, they are the best. 1717 is good for a heavy vehicle, like a GST 7.7/LST XXL conversion, while 1518/1520's are better for lighter vehicles, for example a truggy like Losi 8ight-T or a MT like the Savage (Not as heavy as the GST/XXL).
The 1717 is slightly larger in diameter, so finding a mount for it will be harder than the "standard" 1518/1520 sizes.
