RE: Nitro direct drive
ill keep looking for the top speed record for a nitro.
you cant compare a full RC nitro truck to a tether car. There is soo little to those. 2 tires, no steering, aero body, direct drive screemer nitro.
when you figure that the top electric rc speed record is 164 and that was done with a 11 HP electric motor in a full carbon fiber car....you can see how 100mph with a heavier nitro (even with a 5hp motor) is a tough task.
