I've been hesitant to reply to any of these because, frankly, reading your posts makes me dizzy. You ask questions like where a glow plug is and requesting a tutorial on how to change one, now suddenly you're an expert tuner because you spoke with your cousin? Hey, I know where the moon is, that is orbits the earth every 28 days, that we only see one side of it, that the gravitational force on the face is 1/6th earth's and that man has actually landed there. Does that make me an astronomer? My point is, working with your cousin for a day or two does not make you an expert nor does it give you the right to be rude and disrespectful to a member that clearly was trying to help you! You are simply looking for someone to give you the answer you want to hear, so here it goes:
Yeah, the Associated LRP Z.12R Team Engine is an awesome engine! It'll literally melt the rubber off the rims!
However, keep in mind the following:
1. I don't own a RS4 3 Evo, so I have no idea if it'll fit.
2. I don't know poop about AE engines, so for all I know it's manufactured by Oompa-Loompa's when they're not making Wonka bars.
3. I have yet to see a R/C car got 70 MPH and I'd wonder why in the hell I'd need one to go that fast anyway?
4. I don't know you're gearing, so how the hell should I know if it'll go 70? Hell, I can take the electric motor from and erector set and make it go 70!
Look, clearly you're excited about the hobby, and that is awesome! You're at the right place to ask questions and seek advice, but if you feel it necessary to get lippy with a member because they're not telling you what you want to hear, do us all a favor and go somewhere else. Folks like Racin_38, Plaidfish, .21RC10GT and many others have provided me with invaluable tips and advice, so yes, it pisses me off when you ask a question then respond like a spoiled smart-ass to the answer, especially since it's clear you are new to all of this. Either take the opportunity to learn about all of this or just shut up!
