28/101 will be undergeared .....( Slow)
start with the 33/101 if you need more top speed you will have to gear taller.
yesterday I started out with 28/94 ended up with 32/94 ..
If you gear taller than 32/94 , expect the controller & motor to reach Max temperature`s...
Would`nt suggest going taller unless you have a fan on the both the controller & motor....
You should`nt have to though , its very fast with the 32/94...
