do you notice anything on the xt8 that needs upgrading? or needs to be replaced?
anything wrong with it at all you notice?
The only thing I see is that the body posts look like they'll break. I also read on another forum that many guys are drilling a hole all the way through and using a long screw and bolt to fix it. Otherwise, it all looks sweet. I must admit though, mine came with all the plastic blocks replaced with aluminum as well as the front steering knuckles and rear upright hubs.
At the moment I'm using 46/13 in my truggy with a quark, 1515 2.5D (1700kv), 5s2p 8000mah true rc lipo's. It's geared for about 35mph (haven't radared though) and seems like a good speed for racing. Everything stays nice and cool after 6 mins of racing, and uses 1400-1600 mahs, so I might go to a 14t pinion once I get the hang of it a bit more.
For high speed use 46/16 is about the same FDR as I used in my e-maxx without issues.
