See my Response video to see the record Jump video from a couple of years past.
When I worked at Kraft RC systems, Phil Kraft gave me this bike to test, promote and have fun with. I took it to Hawaii when I was on vacation and showed all the hobby stores on Oahu how it ran. It likes those rounded speed bumps in parking lots, and we had lots of fun showing off the First Mass Produced RC motorcycle in history.
It was a challenge to make the steering work, as bikes steer different than car geometry. (Google “How Bicycles turn”, to verify my comments”). The bike is fun and fast. When I took out a tooth on one of the primary gears in the transmission, I was left with no way to run it again. But my machinist friend, Dave Raubinger, who made all the parts for my Hyperfly Prototypes when I was working on that project for Kyosho, volunteered to make some gears for me on his mill. He did a fabulous job, as you can see.
The bike is difficult to run, as it must be balanced and takes a fine finger to keep it upright in turns. Here, the street is a bit narrow for the turn ratio it needs, but none the less this was a fun video to make. Thanks for watching and Subscribing.
