O.K., so I finally got my Slash MT VXL up and running. I need to be clear that im not a noob. I know how to set gear mesh and set trucks up and I know how they work, I know whats going on inside. I keep an eye on temps, and I know how to gear. I have a stampede VXL with the same tires and wheels as my slash MT and ive NEVER had this problem with it.
My setup is as follows,
Stock gearbox (brand new)
VXL motor with a 17 tooth pinion
86 tooth spur (brand new)
Proline 30 series badlands
RPM gear cover
Slipper set to 1/4 turn out
This whole setup is brand new.
Yesterday when I was testing this truck for the first time on the road with a 3S pack it was working perfect. No jumps though. Just flat out running. The slipper was getting broken in and I re-adjusted. Temps were acceptable on 3S but the runs were mostly higher speed.
Then, I took it out to the track. On 3S its obviously super fast. But, I stripped a spur. This has never happened. I also notice the top shaft of the motor was SUPER hot... even the tranny cases were hot... really hot. The motor was really hot. The slipper was hot... clearly everything was hot.
So, thinking it might be heat I put in a new spur and went to a 2S pack. Slipper set the same 1/4 out. Ran for about 5 minutes and stripped another spur (i have to stress... I KNOW HOW TO SET MESH) Ive NEVER stripped a spur on my pede VXL ever.
So, I switched the spur again to another new one and set the slipper just a bit looser this time and... 5 minutes later... stripped spur. The motor, case and slipper are still super hot. Hotter than my pede has ever been.
As i as removing the spur I just tried wiggling it and I noticed it wiggles quite a bit. Like the top shaft might be loose in the case. This would make sense as a cause for my mesh issues. If the spur can wiggle the mesh would loosen.
Does anyone have a similar experience? I have a spare tranny and tonight im going to install it and see if it makes a difference. Ill have to find another 86 tooth spur but I think I have one in my pede. If this top shaft being a bit loose is the issue I assume traxxas will warranty something but what should I be asking for? Case halves? Top shaft? Bearings? Obviously a few 86 tooth spurs. Will they send this stuff without me sending anything back? I hope the new tranny fixes the problem. I want to run this truck .
