Well, the jato is not a very good vehicle for a conversion, I had one and did not like the handling, it was too light in the rear for my taste. Plus it is difficult to gear properly, unless you convert it to revo mod 1 spurs and use mod 1 pinions. The mt1 or 2 seem to have weak diffs, until the al diff cups are added. The Rustler is the best bet for staight line speed out of your list. It is light enough that a mm system will work without excessive heat. If you want 4wd then may I suggest a hot bodies lightning sadium 10. It is a very solid 10th scale truggy that uses regular 10th scale 2.2 truck tires. It has very strong diffs and a solid center spur gear with a slipper clutch. Run that with a 7l feigao on 3s and it will be fast. I have one currrently setup with a hacker c50 13l on 5s lipo and it is easily doing 45mph, and has potential for a lot more. I tried the crt.5 and found the ls10 a better platform for bashing, maybe with mike's extended chassis the crt.5 would be better, but it is about twice as expemsive than a ls10. Utlimate hobbies usually has the ls10 on special for 185 plus free shipping. Sell the nitro stuff and stock radio and the deal gets better.
