This is an HPI Racing HPI85068 Safety Engine Stop system for the HPI Savage Monster Truck. This new item from HPI is a Safety Engine Stop System, designed to make shutting off the nitro engine safe and easy. Just press the conveniently located stop button and the engine immediately stops, no fumbling to pinch the fuel line or covering the hot exhaust necessary. Careful attention has been paid to the design and location to prevent accidental shut-offs. The design incorporates a spring mounted nylon arm that slides against the flywheel when pressed, a safe way to stop the engine that avoids dangerous lean carburetor conditions associated with pinching the fuel line. Installation is simple, all of the necessary mounting points are already on every Savage ever made. Complete instructions and mounting hardware are included.

also another thing... can i put this heat snk head on my rs4? is it a good idea 2 change my heat sink, i have the stock heat sick that comes with the t-15.....
any other recomendations for heat sink heads? perferably HPI... thank you...

heresAlum Heat Sink Head Purp:S21 BB $45.00
Aluminum Heat Sink Head for the Nitro Star 21 BB engine and similar engines that use the same underhead, this 11 fin machined aluminum head not only looks great, it is more durable and keeps the engine cooler for higher performance! Packaged with four head bolts and convenient Allen wrench.

if it says it is for a savage then it is meant for a savage, they are specially mounted on there so it wouldnt go on your rs4 easily, you should just pinch your fuel line anyways at the end of the day, or if you're shutting ti off for a minute, just cover the exhaust, very simple, i have found that if you have a venom fuel bottle, the cap is perfectly round and shuts the engine off the second you cover the hole, also, dont use that heat sink, it is designed for a 21 sized engine, in fact you dont even need to change the heat sink, if you can tune then you wont need a better one, i have heard of people changing heat sinks and then killing their engines because they automatically think that if they can run their engine cooler then they can run it leaner to get the temps back up and gain more power, learn to tune really good on your T-15 and then buy an OS 18 cv-rx, it will last you a long time and you'll be very happy

lol Apollo Must be the spokesmen for the os.18 crv engine

alright, yeah.. i dont think i have ever pinched the fuel line.. i think i always jsut cover then ehxaust... but yeah... no difference, but jsut curious.. and as 4 the head yeah, i wasnt WANTING a head, but if it owuld make a difference 4 30-40 bux then why not... but yeah... true enough... thx...

the only reason i would reccomend getting an aftermarket head is if you live on the equator where it is really hot all the time

hhaha, nope... im above equator in THE T DOT OHHHHHH... lol, toronto canada bro.. but thx n e wayyyy
