RE: Speed props – a difficult task
People have been heating and twisting the APC black Q40 props for some time. Fine for practice or sport use, but highly illegal for organized racing. In the early days of these props, they were pretty heavy for some conditions and motors, so we would tweak them to reduce the load on the motor for practice up here, and use the stock props for racing in the South. Now there are plenty of lighter props and this is not necessary for our racing needs, but definately doable for sport use.
