The hack turns them into fixies.

Extremely pedantic difference but not quite. They'd still be able to coast which makes it single speed. Being able to freewheel or not is the difference between a single speed and a fixed.

Much worse. If you can make the radio controlled servo to throw the chain during sprints this could cause a specific rider to crash.
