I believe I also have a Leopard 1900KV 550 can size. Would prefer to leave it open in case 1 of the 1/8 scale monsters need a replacement, but could consider it if my other options are not suitable.
Any motor I have on hand would use the stock wrap around water sleeve for cooling since technically they're not boat motors.
Sooooo...what do ya'll think about installing the Viper?
