Hopper stats

I'm a little confused with this matter.sorry if im a noob.but...
what stat is based in hopping?
WLK or FLY?
thanks in advance
sorry for my bad engrish

Both affect hopping
It just depends whether your hopper is wlk or fly based

It's funny because I just asked this question around to make sure I didn't destroy a bunch of parts before being certain on how this works...

They pretty much effect Short Boost equally, although on LNDs they get a wlk speed boost so wlk is more efficient then fly on them. Other then that it's pretty equal, but it's best to stick with stats you'd actually want on the bot. (AKA, if it's an AIR bot, don't get a crapload of wlk, just get fly for obvious reasons)
