Query: Must have for brushless

This is a must for a brushless Stampede. It keeps it from flipping, and also saves your transmission from getting scraped up on the ground. I would recommend it, and it works great. The wheels have a very long life, and can be upgraded to actual rubber easily. It is also adjustable, so you can adjust how high it will let your car wheelie. The only thing I don't like is one side comes unsnapped every 5 runs or so. But snapping it back on a few times is alot easier than replacing the transmission that gets ground off without the wheelie bar. Highly recommend. Great product.
