Plus Your Biggest Questions Answered! After it became the first RC car to drive beyond 250mph, you've had hundreds of questions about the Mach Reaper:
✅ Why I use foam tyres instead of rubber
✅ How I keep the car in a straight line at over 250mph
✅ Why the Mach Reaper looks nothing like a conventional RC car
✅ Whether it could go even faster
✅ How it compares in 0 to 250mph acceleration with the Koenigsegg Jesko Absolut
✅ What's planned for the next ROSSA event... and beyond
While preparing for ROSSA Round 2 on the motor dyno, I also give a sneak peek at the next stage of Project 250, including tyre development, running on 20S, and one very special mission for The Beast later this year.
If you've got more questions, leave them in the comments—I read every one, and they often inspire future videos.
