PLEASE READ ENTIRE LISTING BEFORE ORDERING. Protect your Castle Like a King!! Introducing the DRAGONSLAYER heatsink & fan combo now in RED, YELLOW, MILITARY OLIVE GREEN, BLACK, NEON GREEN, PURPLE, SILVER, BLUE, PINK,GRAY, WHITE & ORANGE . We all know after some serious play time or a fast competetive race our Mamba Monster 2200kv and 2650kv motors are so hot it's like a Dragon blew fire into our motors and the only thing offered to us is a cheap plastic fan you have to zip tie to your motor and it doesn't cool a thing. Well say goodbye to the Dragons fire with the DRAGONSLAYER heatsink and fan combo that plugs right into your receiver using very little power, much less than even what your steering servo uses. Now this is not a cheap clip on either, you will have to remove your motor then slide it into the aircraft aluminum heatsink and then reinstall motor. I have this heatsink and fan combo on both my Buggy and my Dirt Oval car and my motors have NEVER run so cool till now. I'm an avid racer and when I complete a 6 to 8 minute race and my motor is COOL TO THE TOUCH, that says it all. I've had my friends testing this heatsink and fan combo on there Dirt Oval cars and Buggies as I do, also on their Emaxx, Erevo,and Savage monster trucks, and all of them are having the same results. The Heat sink is made of a heavy duty yet light weight aircraft aluminum that is designed to absorb and displace heat rapidly thus protecting your motor from abusive heat that can weaken or destroy your motor. The heatsink has a 1.64" inner diameter and is 2.66" long and the fan is 2" x 2" and has high rpm for fast cooling, as much as 35 deg. cooler and this is the only place you can buy the DRAGONSLAYER . As pictured I have the Castle 2200kv motor in my dirt oval and the heatsink slides right on, and I have the Castle 2650kv motor on my buggy and the heat sink for this motor had to be trimmed so to fit around the motor wires as this motor is slighty shorter than the 2200kv and I will be happy to trim for you just indicate which motor you have during check out with a note to seller and it will be done. This heat sink and fan combo will fit many other motors and brands like Turnigy Trackstar 2650kv & 2560kv, Hpi Flux Scream & Alphastar and Tekin T8 2000kv motors just check your motors measurements. Please note that this heatsink when used with the castle version (2) 2200kv motor will need to be adjusted for size, you will have to remove fan and then squeeze heatsink in your hand to reduce diameter to fit this motor then re-install fan.  SHIPPING INFO PLEASE READ BEFORE ORDERING;orders will be processes every Friday. orders must be received by 5pm e.s.t. on Friday orders received after 5pm will not be processed until the following Friday Please indicate which motor you have from the ones listed above and choice of color or a standard heatsink and random color will be sent.
