I think First you are OVER geared..... good straight away speed.. but NO torque to maintain any speed in the corners..
your words.. " and I pass all the other buggies on the single straight "
how to you "Turn" the steering wheel" ?? .. smooth and deliberate .. or just slam the steering wheel to the stop:??
then there is the "Racing" LINE.... arc the turn.. not steer the turn..
racing is NOT driving...
racing line... start wide, turn in, clip the apex, drift out of the corner.. maintain speed...
turning looses speed...
there is a Whole School on "race" driving.. real cars... RC cars..all the same.
