Bumping this thread....
Who here is still racing their Mi4's? Where are you located and what surface are you racing them on?
I'm racing a Mi4 LP in VTA, mostly on asphalt (Central Texas) and occasionally on carpet. Having a blast with it. I recently recommissioned an Mi3.5 for 17.5 Blinky duty, but am looking to upgrade. I'm not a Schuey loyalist so I'm not committed to going for the Mi5, although there's one for sale here locally and it's a great deal.
I wouldn't mind staying in the Mi4 lineup since I've got a bunch of spares. I've been looking for Mi4 CXLs, but it seems as though not many are giving them up yet. For those of you who aren't racing Mi4s, what chassis did you move on to?
