I run the Paradigm series Monters and P2K motors for stock class I run my own creation for Mod class I use a freshly zapped Fantom can/ a Integy 12X6 armiture/ Orion V2 Endbell / Sprint Brushes/ Medium springs.
and I run Reedy 19T Quad Mag spec for 19T class.
These seem to give me th ebest results.
I realy recommend the Paradigm series, they support there stuff and if you need a motor tune up all you have to do is send your motor in + $2.00 for shipping and they will do their magic for nothing. Or if you are at a big race they will do it there for Nothing.
I can't wait to see what they do with the V2's I will be running one of them for sure.
That is what I love about Opinions....they always are mine and no one elses. So I can never be wrong....hehehehe
