Have you thought about adding the TLT-1? It's designated by Tamiya to be 1/18 scale even though it may be slightly larger than other 1/18's. I'd also like to take this opportunity to say that the Mini Quake RTR and SE are both awesome trucks! I am baffled as to why they are not more popular as I have found them to be very quick and able four-wheel driven beasts! I finally got a Mini-T after seeing so much more written about it and have been very let down by its performance. I'm not trying to start anything and I realize they're different types of cars, but the RTR performance isn't even comparable! I say Duratrax gets an A+ on their Mini Quakes!
Nope, I was messing with them the night before I left and came up with this awesome idea that has never been done before, so im kinda anxious to get back and mess with that, I think I may be on to something totally unique, as well as the fact Im curious to see the contents in my package from Driven Productions.
