RickyIS300.. First off... It is your opinion, But i think you are WRONG
...
As for the 4200's.. They are real good.. I am very happy with testing so far.. There about 20-30 seconds more runtime with the same volts as the 3800's...
I think they will be legal for most races other then roar next year wich is about 90% of the races...
