Hi all Just took my brand new Fms Fcx18 to the local woods and I encountered an issue while going up the hill - it stutters (video attached). It only does it in 1st gear. It only does it going forward (reverse up the same hill is fine). It only does it going up the hill - on a flat surface it's absolutely fine. In 2nd gear it goes up the same hill fine (I mean going slow not blasting up it). I've taken portal axles, diffs and gearbox apart (thought gears might be slipping) and it all looks fine. Not too sure where to go next with it. Any ideas what might be causing this? PXL_20240315_154555006.mp4

Hi all I recently got a FTX Outback Gladius and I'm loving that thing. I have noticed however that dip switches on the controller that are supposed to control F/B/R ,F/R and drag brake don't seem to be doing anything. Truck is always is F/R mode with 100% drag brake, no matter what positions the dip switches are in. I've looked on line and watched a whole bunch of reviews but can't find anything other than they're supposed to be doing the things they say they do. Any idea why it might not be working and how to fix it? Or does this truck not have these options and the controller is also used on other models that do have these functions? I'll also add that the truck only had 1 run for around 90 minutes. Any help would be appreciated.
