I have the GST 7.7 that I converted to brushless using a Mamba Monster system and the SMRC innovations plate build kit. I freaking love it! It;s a beast but get ready to break some parts if you tumble. I snapped a front Aluminum A arm and a tie rod last night at the park after a whole 7 minutes of driving. But it is a fantastic truck, i;'d liek to see mine against a RTR brushless GST
