Blackbolt XBR 220 Racing Drone from Team Big Whoop

$65.00$95.00

The Blackbolt XBR 220 Racing quadcopter.  This is a no-bs, race built machine that is designed for one thing-winning races.  This frame is 100% made in our home state of Colorado, USA by Chris Fischer and the team at BlackBolt engineering Team Big Whoop. We’ve been following the races and watching who is leaving others in the dust, and the XBR is hands-down the fastest quad that we have seen.  The reason? 12:1 power to weight ratio- symmetrical, simple, smart design, – and a determination to win races sets this frame apart from all of the others.

If you want the fastest, best flying, most no-bullSH*! racing quad available, the XBR 220 is it. We recommend this frame to advanced builders as it is a tight/precise build and requires a higher skill set than the typical H style quad. please see the introduction below to get an idea of how tight the build clearances are. Made proudly in Colorado, USA.

Description

Includes:

  • Blackbolt XBR  220 Carbon Fiber Quadcopter frame
  • Blackbolt XBR 220 Injection  Moulded Canopy (If shown in the title, or selected in the description)
  • 4x 4pc M3x8 aluminum bolts.

The Blackbolt XBR 220 is a purpose build high performance racing quad, with no extra frills or fancy features. It was designed for speed and agility on the race course and nothing more. With inspiration from acrobatic quadcopters such as Soma’s warpquad and flight styles of the great Warthox/Quadmovr, the Blackbolt XBR 220 is an extremely capable FPV racing machine, as well as an amazing freestyle rig for tearing through the sky at ludicrous speeds. Breaking away from the mold of the H quad, Black Bolt has distilled the racing multirotor to its bare necessities, a symmetric X body shape with a centralized mass, allowing for a very stable yet nimble platform even at speeds upwards of 70+ MPH. https://youtu.be/a2eNYflwCTk

Made in the USA

Made in the USA

Made In America The Blackbolt XBR 220 is made from the some of the highest quality materials available, the carbon is manufactured in America with an ISO 9001 certification, this is the same stuff companies such as NASA, Boeing, and Lockheed Martin use. Furthermore, the frames are manufactured by the designer himself, right here in Colorado.

Smallest mass Mass or weight is one of the biggest factors in any racing vehicle, but even more so for an aircraft. Tires grip a road directly in a car, but in the air you are moving through a compressible fluid. In order to have the dynamic response needed to win a technical race track, we have to overcome cutting through squishy air. Obviously the best way to do that is to have less to move. Aerial racecraft need to have the smallest mass they can get away with and still perform all the necessary functions to win a race. This was the idea behind the design of the Blackbolt XBR 220.

Unibody The choice to use a one piece frame was a very important one. Yes it would be nice to bolt on a new arm when one breaks, also it is cheaper to make a frame with bolt on arms that can be nested better in a sheet. However the lack of bolts needed for this frame is how we accommodate the weight of FPV gear, and the design lends itself to not breaking arms. This is the biggest secret sauce of this frame. Minimal metal bolts! As racing evolves and the pilot skill increases, frame design will become much more important and none of the top pilots will allow that much hardware on their aircraft ever again. The Box  With the choice for a unibody frame came the desire to bolster the arms for impact. Adding a box of carbon gusseting the arms, significantly increases stiffness and crash strength of the frame in both the horizontal and vertical plane. As an added benefit, the box also tends to influence the quad to roll in a crash, which is the best way to take energy out of an impact. There have been other frames to do this as well and they usually have aesthetically pleasing curves to them as they resemble a spider web. Those are very nice looking frames but the curve in the gusset adds unnecessary material and doesn’t use the weave of carbon fiber effectively. Because of the increase in stiffness, thinner carbon fiber can be used, allowing for even lighter setups. Smallest moment of inertia

The moment of inertia is a mathematical variable that describes the energy it takes to rotate an object. Having a centralized mass allows for the pitch and roll of the Blackbolt XBR 220 to respond to control inputs in a balanced manner. With the centralized weight both axis are rotating around the middle equally, creating a quad that is responsive no matter the direction of the control input. A hard design rule involved keeping material on the outside of the frame as minimal as possible. Symmetric X

The Symmetrical X design has quite a few positives. First of all it allows for the absolute smallest possible size that will fit the appropriate prop. The Blackbolt XBR 220 fits 6” props on a 220mm MTM quadcopter. Along with the small size the X design helps reduce the pain of tuning, as the pitch and the roll axis will be identical to tune. Lastly, the symmetric X allows for the mass to be centralized creating more responsive and nimble racer. Camera position The whole point of the H quad was to spread the motors apart to leave a gap in the props to see through with a camera. That is an antiquated idea from a time where quads moved very slowly. Now we have racing and our average pitch during a flight is significant(20°-30°). That pitch gives the ability to position the camera above the two front props. To do that it is positioned near the rear of the aircraft allowing the front props to be well below the center of the screen and out of a distracting view. With the use of a wide angle lens, a flat horizon can still be seen for hovering even with a camera tilt of 30°. New Hoods

3D printed hoods allows for unlimited modification. Any camera angle or accessory can be created for the Blackbolt XBR 220, future plans are to inset and integrate a Polaroid Cube+ into the hood of an Blackbolt XBR 220 to get that buttery smooth 1080p 60fps that we all have grown to love in our FPV videos. But possibilities are endless, and we can’t wait to see what everyone creates! The hood for the Blackbolt XBR 220 will always be available for download free for anyone who owns a 3D printer or has access to one. Remember many local libraries, schools and makerspaces now have 3D printers you are more than likely able to use. https://youtu.be/XihX4Q-az74 12:1 Power to weight ratio!! What we all care about, power! With our recommended build a thrust to weight ratio of 12 to 1. This kind of power is not common place yet in the multirotor industry and until it is there will be lots of people claiming your video is unnaturally sped up. Take this as the highest form of flattery while you blaze the sky and amaze the locals. This kind of power is not only for the top pilot either. You can fly quite conservative with this setup and only “tap into it” to recover from mistakes. There have been several testimonials that say they wish they could have learned on a quad with that much room for error, and that it would have helped them learn much faster.
