Hobao Racing - Pushing RC design and technology to the limits and beyond

Hyper 21

Supplied as standard in HoBao 1/8th scale nitro vehicles, the Hyper range of 3.5cc engines are a perfect partner for just about any 1/8th scale 3.5cc application.

Sensibly priced, yet providing astonishing performance, value for money can definitely be found here. Despite the inexpensive price tag, the Hyper 21 rear exhaust still boasts many design features associated with more expensive Italian racing engines. A racing 3-needle carb is included for better adjustment and standard and SG crank versions available, with and without starter.

Hyper 21 Racing

Developed from the very successful, and reliable standard Hyper 21 supplied in HoBao&39;s range of nitro cars and trucks, this new 8-port version has been refined for racing purposes, and supplies a smoother power band, making it an ideal choice for good top speed and easy driving. The 8-port has already matched up to more expensive Italian brands in the hands of the HoBao Hyper 7 rallycross team, and could be a surprise package in 2003. A racing 3-needle carb is included, along with a large heatsink head for maximum heat dissipation. Parts are available to convert 3-port Hyper 21 to the new 8-port version.
