Hmmm, the only difference I have seen between my Novak and Castle is, Novak cant do as high voltage, and Castle takes longer for repairs. I have been setting track speed records and holding down 1st place on our new neighborhood track with my Novak, while my Castle has been in repair.
Granted we arent pro's on our track, but I have been keeping a head of E-revo's and nitro's with a good old Orange system.
I just dont see the advantage unless your into speed runs.
I have only had to use each company once to repair stuff. The orange company was wayy faster on return and much nicer on the phone.
To each his own I guess.
It is nice to know that each company tries to take care of the customer.
