Just finished building the 4x4 Crawler and it was a fun build but as a remote control car it is . . . in a word . . . SLOW! I know it's powerful and can climb over stuff but sometimes there is nothing to crawl over and I'd rather it be faster. Are there any other gear configurations that would make it a bit more exciting?
You need these old school 5292 puppies ;-) 2 of them.

You're gonna have to do some after-market mods but those are very powerful , I have them from the 8366 set. But as you can see in the review, there are pro's and con's on every engine.
I suggest reading it in full, it's an amazing source of information and you'll learn a lot like I did. There's a nice poster about them.
It has 2 different outputs which makes it so fun to make something that can use them both. Speed or torque. They will drain your batteries for sure anyway you use it.
