Except for the slipper clutch hop-up I stayed completely stock setup and box art with mine. I’ve run 5 x 2S packs through it in its first week and so far no issues and no leaking shocks. I love it, really fun to build and to drive. I really like the stock wheels and tyres in the flesh. They’re really fun handling on loose sand, dirt and loam.
It makes my “better specced” TD4 feel a very bland drive in comparison. I’m not a TD4 critic - I’ve really enjoyed it too - but it has a lot of shortcomings. Where the TD4 felt compromised or ordinary the BB-01 makes you feel… like… what else could this thing do? The BBX is imaginative rather than derivative!
Actually, one and only fault so far is I popped a drive shaft on the first run. I swapped the rear wheel hub spacers around as suggested in the manual and since then it’s not happened again despite rolling it at much higher speeds.
