The Radical is one of the lightest 5” racing frames available right now at only 62g including assembly hardware. If you’re savvy with racing quads and already have an understanding of an average frame weight, you’re probably thinking that a bunch of compromises were made to get to 62g for a 5” frame that doesn’t look like it’s made from twigs. The truth is that any unusual features are for increasing its efficiency in the role of a racing frame, not just to lose weight. However, when you’re on a mission to fight gravity, weight loss is a sweet sweet bonus, no doubt about that. Weight loss not only increases your power to weight ratio but also your overall efficiency in flight. Plus, reduced mass is reduced inertia, which makes for a more dynamic racer that can accelerate faster as well as pull out of dives with ease.

We gave the Rad 5” skinny, 4mm thick 3k carbon fibre, low drag arms (the 7″ arm is 5mm thick). This offers some race advantages over a wider arm. The first is that turbulence on the arms from the props are reduced for cleaner air. The second is an increase in thrust efficiency as the flow of thrust isn’t having to push down on an arm with a larger surface area. Lastly, the overall profile is smaller, so less overall drag. The arms can be removed quickly and easily in the field or between race heats if needed, as you only need to remove 2 bolts from the frame, 2 from the motor. The arms interlock at the core of the frame and the holes that the bolts pass through to secure the arms are tight by design, so there is zero slack in the individual arms and any impact stresses are spread across the entire airframe. This means the amount of hardware required to keep the frame from falling to bits in use is minimal, which means further weight loss.

As usual, we used high grade Japanese carbon fibre and have cut the arms according to weave pattern, for optimal strength. We added a bevelled edge to all the plates in this kit for a premium feel and to preserve the edges. The Radical is not only one of the lightest, it’s also one of the best value for money racing frames on the market today, costing half as much as many other racing frames, with some of these frames weighing nearly twice as much. Other Radical accessories are also available separately, be sure to look for Radical accessories in the accessories section of our shop or in the related products section below. You can also make a request for parts to be made if you can’t find what you need. Who else does that?
