If it blew out dust and dirt after first firing, it's probably got dirt in the gearbox too. And the gearbox is what's doing most of the work in the Stampede. It's important that it works optimally.

Do what Mojo said and crack it open. Make sure the gearbox is clean and well lubed. Use copious amounts of silicone or white lithium grease. Also check the wiring. Frayed wiring and corroded contacts can have a serious impact on performance.

At the end of the day though, the stock Stampede is not a particularly good performer, gray or orange trigger. It benefits greatly from an AR removal. If you are so inclined, you'll see a huge increase in range and velocity. For better ROF you can optionally run it on three IMRs without any modifications.

Have fun !
