i'm happy to read that Novak is interested in innovation. they could just continue to push the current HV line, and people (not us in this small power hungry segment) would continue to buy it. it's great when companies like Novak ask for suggestions, and
listen, to better and expand their product line.
i had a HV 6.5 in a heavier-than-stock maxx for over a year with absolutely NO problems. but i
followed the instructions and didn't overgear it. sure it wasn't as fast as i would've liked, but the power and speed was better than the stock titans - just as advertised.
look at Novak's crawling segment. when the first crawler system came out, it didn't have drag brakes. guys on the crawling forums said it was a great system otherwise, lots and lots of power, but that this feature was needed. Novak answered pretty quickly with a solution (quickly, considering all that most likely went into that software revision).
i think between the new systems that Novak, Tekin and Castle are coming out with, PLUS this new conversion kit that Novak is developing... we're about to see a new frontier!
