In this episode of our DIY backyard launch coaster project, Tilley’s Terror hits a major snag—our Variable Frequency Drive (VFD) keeps internally blowing up during braking! The inverter-based braking is just too aggressive, and we need a safer, more reliable solution. Watch as we troubleshoot the issue, explore better braking options using a DC motor, and upgrade our motor from 2 HP to a beefy 5 HP to handle the launch demands. It’s full of sparks, strategy, and serious coaster engineering!
