The REDS 521 Sport .21 Broken In Off-Road Competition Buggy Engine
Combo with 2143 tuned pipe and M manifold (REDKM210011), delivers a high
end balance of innovation, quality and performance - at a mid range
street price. The 521 Sport features technical changes in the 5 port
sleeve, combined with updated materials to offer users high reliability,
tuning stability and fuel mileage. The 521 Sport guarantees excellent
performance at a reasonable price.
This combo has been broken in using a specific blend of oil for
breaking-in nitro engines using the Oil Bath Lapping Machines. The
pre-break-in process saves time, fuel and increases the performance over
the traditional break-in process. Only a quick, post oil bath, break in
process is keeping you from experiencing quality and performance.
Features:
- ALUMINUM CARBURETOR: 521 Sport engine includes the same aluminum carburetor as 721 engines to guarantee reliability and tuning stability. The insulator bushing has been improved with aerospace grade ultra high strength polymer. Furthermore, the GEN2 carburetor features a double grub screw joint link to allow positioning and fitting with the any servo linkage system.
- STATE OF THE ART DIE CASTING: The unique high stiffness crankcase design is produced with a high quality pressure die casting process and special aluminum alloy developed by REDS Racing engineers to guarantee higher stiffness and strength.
- 5 PORT TECHNOLOGY: The piston and sleeve features updated materials. Thanks to updated 5 port technology, this engine provides really good fuel mileage and a smooth power band.
- HANDMADE, TUNED AND ASSEMBLED: Every single engine
is hand inspected and compression checked inside REDS Racing
headquarters by Mario Rossi to achieve the highest quality standards.
