I have had both. the STOCK flux tranny is junk, but once you buy the HD gears for it its fine. However the revo is 100% plastic, the tranny seemed to hold up well, but the axles did not. I went through a plastic axle with every set of battery packs. I bought 2 sets of four axles on ebay and used them all, and this was on 4s mind you. I sold the revo and got the flux. So far on the flux running 5s and ocassional 6s the only power/tourque related failures have been 2 pinion gears. I sawapped out the tranny gears to the HD units before the stockers failed but they were showing considerable wear and there was metal dust everywhere inside the tranny. The HD gears still look like new. Hope this helps
