There were plenty of guys over a long of period of time complaining of their Savage XL transmissions blowing up with even stock Piccos.. Maybe the diffs themselves have improved, but overall the Savage drivetrain is still questionable.. That of the Losi MT's is frankly not. And yes that is fairly objective, having spent enough time on both Savage and Losi forums for the last 5+ years. You just don't see people having issues with stock LST's like you do with Savages...

I think a Savage X 4.6 is a great RC to get started. And I'll even allow that quality may have improved since I had mine.. But put in bigger, more powerful engines, and I'm not so sure.. And that's just keeping things to quality. Not to even start in on handling, etc.. But this Savage vs. Losi talk is beside the point, so leave it...

In any case, I don't have a Flux, and again, don't bother reading about them. But I seriously doubt a Flux even on 4S is going to be less maintanance than an X4.6.. And it wouldn't surprise me at all if it were more.
