i never played with restrictors until recently.
what a different motor. i threw in a 8mm from not having anything, and i wanna say my run time almost doubled! my .28 used to be a gas hog! now when i come back for a splash of fuel, i can see about 40% left in the tank.. what a huge difference!
i was getting 10 mins before on a tank, im curious to see what im going to get with the 8mm. also, throttle seams alot smoother.. still decent power.. but not break the tires loose and scream.. so i can see driveablity only getting better.
