It was a pretty good hit. I'm pretty sure the RB5 would have spun around and drove away. I know another guy that snapped one as well.

If I get time at work I may make more. I'm hoping somebody makes a full rack soon.

The stock plastic feels weaker than the carbon composite that comes with the RB5 t-plate pack UMW505B. I have those and will be trying them before going alum.

Let me throw this out. I have no idea how to adjust or just become a better pilot.

When landing nose low and not level the car wanted to flip and roll over. Never had this before with other buggies. It was almost like traction roll but only on landing. The car showed no signs of traction roll anywhere else.

Thought I would share. Thoughts?

Yes wheels turned slightly. 2 separate jumps. One turns right right after the jump and the other is a slight left.

u really dont wanna land with your wheels turned, and if you are landing nose down thats a lot of pressure and weight thats goin to your outside wheel so with a decent set of tires that hook up when you have all that pressure applied to one wheel that isnt goin to slip when it lands, its gonna roll. and if you are landing with the wheels turned more than likely they are turned in the air causing your buggy to lean opposite of the way you are turning , so you are basically landing on one tire with momentum already leaning one way, its gonna roll. maybe a bit thicker oil in the front may help but i think the best answer is just you have to get it controlled in the air better, jump and land flat with wheels straight

I kind of was thinking along these lines. Tires are brand new vs broken in ones on my old buggy. I will try the oil just for fun. The car is damn nice everywhere so I don't want to mess with much. Just practice and be better.

work on a wheel wiggle in the air, flattens your buggy right out, just a quick turn right and left, if you work on it pretty soon it becomes second nature and you just do it without thinking about it
