look, i have about 4 1/2 slashes, and i made one of mine a speed demend just like u our talking about. bacicaly, you will need to ether find a good brushlesss system,l u can trade in a old brushed for a brushless to get a discount, then get a 3 cell lipo battery, lastly, you will need a larg pionion gear maby 28 tooth or somthing around there, and you will be able to cruse at about a top speed of 70mph, ill have a video of mine on yoputube soon, my useername is rcmike221 check it out if u want, or let me know if there is a problem.
Im all for it, but you might need to get a new body. SC trucks have parachutes more then bodies, and Ive not only seen on you-tube but in person on my friends brushless Slash, Either they get to light and impossible to control, Blow over backwards, or my favorite thing, stay wheels down but launch into the air. It actually is neat when that happeneds, but I think 100mph isn't physically possible with a SCs
If you can I would love to see it though. Definitely would be a record of some sort
