is my jato 3.3 supposed to rev up really high when if flips over?

Yep, but it will stop that if you put on the brake[&o]

thanks alot, and would you recommend me getting the RPM A-arms or the aluminum A-arms, and what other parts should i look into?

RPM a-arm.

When the truck is up side down it not longer picks up fuel from the tank and starts to lean out. This is why the engine starts revving up just like it does right before it runs out of fuel. Yes with any Traxxas RPM A arms are a must!

dont get aluminum a arms theyll just bend.
