RE: Kyosho Inferno us sports Ready Set?????
For the money you cannot beat the power of a Sportwerks .26. They are $140 and my SW .21 will keep up with some of the higher end engines. I was slightly outrunning a Novarossi P5 at one point. All of mine have lasted about 6 gallons of fuel and its only $50 for a new piston and sleeve.
