Overview:

In circle track classes that mandate two-barrel carburetors, customizing a street carburetor has been the norm for decades. Not anymore. Designed from the ground up to meet the unique demands of circle track racing, QFT's new XP-Series offers the performance benefits of a custom carburetor in an affordable, turnkey, class-legal package. At a bare minimum, modifying a standard street carburetor for circle track duty typically involves changing the throttle-plates, floats, and metering blocks. These custom modifications can easily exceed the cost of a turnkey QFT two-barrel carb while still lacking many of the key features that only a clean-sheet redesign can offer. A high-flow aluminum main body design centers the venturi over the throttle-body assembly. To further increase airflow, QFT centers the air horn over the venturi, removes the choke tower, and carefully profiles the air inlet transition. The result is enhanced airflow and fuel distribution, which improves throttle-response and horsepower. All XP-Series carburetors are equipped with roller bearing seals which provide smoother throttle response, less wear on shaft, and longer life. Available in 500- and 600 cfm sizes, the XP-Series sets a new standard in two-barrel circle track carbs. High-flow aluminum main body with centered venturi for improved performance and better air/fuel distribution Black anodized billet 2-Circuit metering block and throttle body Throttle body incorporates roller bearing seals which provide smoother operation, less wear on shaft, and longer life Anti-siphon check valve in main body to reduce pump pull-over Changeable emulsion bleeds and power valve channel restrictions for better tuning capabilities Dual inlet fuel bowl with #8AN fittings Dual sight glass windows for easy float adjustment Single wedge circle track float Exclusive Black Diamond® coating for enhanced corrosion protection and appearance. Provides a 6% reduction in fuel temperature.

    Works well, good quality
    Size: 14 gauge silicone wire 5ft and 5ft, Color: silicone wire red and black
    This has worked well over the last few years. Used moslty on battery leads for quadcopters. The wire and insulation has held up well, is good quality, solders fine. I have since used other BNTECHGO silicone wire as well, and not been dissapointed.

    Great for re-wiring a 12/24v DC PSU for a 3D Printer
    Size: 14 gauge silicone wire 10ft and 10ft, Color: silicone wire red and black
    I'm familiar with this wire as it was just coming to market as I was fading out of the RC hobby back in ... well the 90's? When I got a roughly cared for and damaged CR-10 for cheap, I decided to remodel it and place the guts and gear under the frame. This wire is thick enough to wire the power plug, MOSFett, and main board with no concern for the 30 A amperage it could draw. It crimped easily, stripped cleanly and is super supple. I paired this with a 7 color pack to re-wire things to arrange plugs where I needed them to be. It's good wire and I may even use some when I dig out my old RC-10 graphite or Bo-Link fiberglass chassis...
