Hello friends, brand new here but I've definitely lurked these forums for a while.
I think I've vacuumed up about all the information I possibly could online about this truck and if I am missing some key places for information (SBR2 or general RC teching/maintenance of this type/scale), there just isn't a lot of info about its inner workings that I can find. Losi has a laughable amount of support officially on their site besides the meager manual included. Like this is a no joke truck of price and size, and I think much more through documentation with some more advanced possibilities for tuning and longer term maintenance planning would have been nice to have right out of the manual, but binding the receiver is in there so thats good.
I do not come from an automotive background but I can definitely see a lot of parts generally function like their 1/1 counterparts and I think thats where my struggles the most are as I gain more interest and experience in this hobby. Are there any sites or youtube channels that kinda go into some detail about RC differentials and transmission stuff? I have the most questions in the drivetrain areas of the truck. Like an example of something more advanced being like shimming all your gears for a more perfect mesh and also why you don't shim them! Because if I think I might need to because I notice play, its nice to know the play is there for a reason too. I dunno thats a lot to ask and pretty ambiguous but maybe I'm missing a great writeup somewhere.
So I'll try and be brief about my actual trucks problem I'm currently triaging. I crashed pretty hard a few weeks ago, end over end on concrete and it was not my favorite day all-in-all. I'm guessing that crash was the cause of the issue I'm having, although it didnt start maybe 2 weeks later. My truck won't drive a straight line. Trim tunings played with hundreds of times, AVC off and full blast and the issue seems worse with AVC on telling me that something is physical is out of wack that the gryro can't correct for.
The truck drives slowly left then right kinda like a drunk driver that can't stay in their lane. Like wheel wobble but over a much larger cycle of the drivetrain. The wheels spin fine no binding and no wobbling not normal for the truck. I tore the truck down and my center driveshaft is ever so slightly bent. My center differential and the surrounding case plastic don't fit super cleanly together. The rear diff and axle seem fine and I'm about to tear down the front end. My question:
For a vehicle that has this long multi-section drivetrain, if my center shaft is bent, what kind of things happen to the truck while its being operated? Like if anyone has experienced this before. Because to me it looks like the bent shaft and continued driving on it after has bent other parts down the line as a result of its new angles its rotating. Can I expect to see diff spider gears stripping and non-symetrical wear eventually causing one side of the truck to start failing? Its a big question but kind of what I wish I had more knowledge about. I could very well have caused wear and damage to too many moving parts down the powertrain to actually fix this and that would suck super bad.
Yeah if anyone does read this thank you. Appreciate any insights or tips for info regarding tuning and theory.
