The Ryft is a blast! But as stated above, it does need some upgrades out of the box. I have not gone to aluminum axles but have broken one or two. A sensored motor and locked diffs help for more control. Lowering it keeps it from flipping as much at speed. I went to the 2 speed which adds some slop, but is much easier on electronics and you can get way better run times if you want to do some trailing/crawling in low gear. While it took a little time to get mine to where it's at now, it has been totally worth it.

If not jumping it, don't think alum axles are needed. If small jumps or crawling, a cheaper option is alum axle inserts.

1/4 id aluminium tubing and machined them to fit, so no axle breakages so far lol
