Don't you just love it when something beautiful also turns out to be functional. These Thermo reactive frames change color at 100°F(37°C). Not only do they look awesome, but they indicate when motors get hot by changing color around the motor mounts.
After a flight these frames will let you know when they have cooled back down which will indicate when it is a good time to fly again, thus extending the life of your motors.
We highly recommend these frames with Ludicrous motors as those suckers get really hot!
