Port my current M1 single plane or install the RPM Air Gap?

That’s a low cost test.

I have an RPM in the box. The guy that helped build the motor says “don’t touch it! “

… as I need to work on better tires and brakes first (chassis stuff). Sound familiar ?

Yes it does and I'm trying to remember exactly why and when.
Suspension suspension suspension, just when you think it's good you add power and find out it needs to be better or coulda shoulda been better already.
