I finally got to run my UDR on a track yesterday. It worked pretty well! Takes a different driving style than I’m used to, but it was fun! I think the suspension needs to be a little stiffer for loose dirt. I might play with shock oil a little and see how it does.

claytrackstar - don't make it with onboard vid ,,, they stink all shaky and cant see crap.

Nah, seen plenty of good onboard videos. Depends on the terrain too though. At a track it's easy to get decent footage. Also helps a lot if you have an action camera with optical image stabilization. I considered getting one and a Blockbuster body for my 1/10 SCTs, but in the end I figured why put 100€ into that when no one's gonna give a damn about the footage anyway 
As is my footage isn't too terribly shaky, but the resolution is crap (theoretically 720p but actually tends to look worse than a good 480p).

Anyone having heat issues on 6S? I felt the truck was too underpowered on 4s and I'm loving 6S, but even on a 75F degree day a pack of 5500 batts gets the motor close to 200F, which is not good at all. I run on a mix of all terrains, grass, dirt and street all at once, so its not like its trucking thru high grass the whole time. The motor is just so cramped and theres no airflow moving thru the space it just can't stay cool. I was going to put on one of those big hobbywing HSFs but the only way it would fit is if I cut out the area above the motor(facing up on the truck), but then realized theres a mounting point for the roll cage so I can't do it.

The main issue is heatsoak due to the compact design/proximity of the geartrain/motor. I've checked temps after running 6s (though mostly low cut grass) on a 80d+ day and I'm getting in the 155-165 range and that's borderline for that motor. Keep in mind that's WITHOUT the belly pan installed so there is a huge difference in cooling air with/without it.
Anyone want to 3D print a updated belly pan with a NACA duct in it? Sure, debris would be a problem, but it's a thought.

I hear ya. This is one of the disadvantages of having a inverted tub chassis design along having the motor obstructed from much airflow. I thought about running a small duct down to that area to keep the air flow constant from the cockpit. It would also be nice to have some sort of fan in that area to keep airflow constant.

Damn I was wondering how you were keeping it that low. I thought about running it without the bottom pan too but thought it would cause more harm than good. I'm actually installing just the fan from the giant Hobbywing HSF directly on the upper chassis(under the drivers) with a hole cut in it, hopefully this helps. I'm attaching some pics for reference if anyone wants to see or try it, let me know if the pics aren't showing up.
Nice work.
