RE: Fastest hyper 7?
Those things are flying lol, I didn't know there was a buggy world record nice!
I'm not too big on buggies but they are fun and stable, I haven't run this gearing with the stock engine yet just finished the modding last night.
With the stock 2 speed gears 2nd gear was 17/44 and I went 46.8mph with the tiny street tires i have on now (94mm dynamite speed treads).
I'm sure 50-55 would be easy with bigger foams 100mm+, I will run the car this weekend on this new low gearing and stock engine and see what it does.
Ultimately I think one of the high revving .21's will be a better choice, I modified the stock one it screams pretty good now.
