Please see attached video file of one of local race recently held in Singapore. I really can't comprehend what I had done wrong or did not do. All 3 are MS chassis....I am running MA chassis. I am on Mach-Dash (broken in to run @35000RPM @3V regulated voltage; on Ni-MH it always drop below 3V once running on track), large diameter wheel with trimmed tires measuring 26mm, front AT ivot bumper, rear sliding bumper, floating gear set-up). I am really starting to think there is a inner-circle secret barring the common player from achieving top speed - battery booaster? Some kind of device or method which enable their ni-mh battery voltage to stay and not drop? secret method of modding/breaking in motor which allow them to achieve 40,000rpm at 3v? Really at a loss. If i still can't figure it out, then its time to quit this hobby for good. Not a nice feeling to stay in a hobby where you can't compete at all.
