Dang it! About 6 more packs run through it and the rear pinion bearings are shot... again! I either need to buy a bunch of them, or better yet, it's probably time to have Dlux do their big bearing mod.
After having the center diff locked for those 6 packs, I can say that I do like the way the truck drives in loose dirt better. It's much easier to "steer with the rear" now, so it doesn't end up on its roof so much. It can also drive right over tree roots in the park that were getting it stuck previously (not trying to rock crawl with it, just a couple 2"-3" tall roots in a low-ish speed turn, these ones were causing the truck to flip ass-over-tea-kettle if going any faster.) Obviously, the truck is easier to flip when coasting through a turn on asphalt, but it does okay if you are hard on the throttle. I'm certain that the locked center diff is a big contributor to the rear pinion bearing failure since it sends full power through the wheels with traction, all the time... so much so, that it will do unanticipated wheelies (and even backflip) if you're buried in the throttle and the tires find traction. I think I'll try to reduce the punch setting on the ESC to tone that down.
The Promodeler 215v3 servo is performing as I hoped, never lacking speed or power for what I need it to do. It does have enough power to turn the wheels towards the ground and throttle back onto all 4 if you land on your side, which has already saved me from a couple "walks of shame" to go grab my truck.
The Losi light bar meant for the Baja Rey (really meant for the Rock Rey?) requires just a bit of trimming of the windshield frame on the cab to make it fit without interference. It's not nearly as bright as my son's 6" Proline light bar, but his cost twice as much and is run on 2s as opposed to mine plugged into the 6v receiver. For $20, I guess it's alright.
I'm still loving this truck. The Baja Rey's performance/handling is more in line with what I really wanted from RC's when I made the switch from NiCd/NiMh powered electrics to Nitro years ago, but I always missed the simplicity of electrics. I think the Baja Rey on 3s is better than any of our old nitro's in every way!
