    Haha, that's insane. Sounds like Castle just covering their behind. Every form of RC demands that one limits the throttle. Have you even flown a Helicopter? You know what would happen if you didn't limit the throttle? How about raced on road or off road RC? Ever tried going full throttle through turns or the whoops section in off road racing?

    Funny how Novak never seems to have a problem where CC does. Too bad Novak doesn't make Marine ESCs.

          Wow truly bizarre! People posting picture of home cooled esc, guys talking about cogging problems with a different esc, One guy can see through the heatshrink in the two pics on HK and claims it's already shorted out!
          Take a pill It's just a post to say something new and cheap is out there!

              You guys bring up some great concerns. I was working with ********** last year and for about 3 months this year on ESC's. During our interaction i was shown several sites that dealt with very high performance ESC for electric bikes, cars and planes, some you can find online, and some of their own sites. I asked what they thought about the current esc's in use, the reply was kinda comical as this was a direct quote, "You guys are running on the ragged edge of unit failure and we find it amazing these units even last as long as you have stated", this from a high tech company that deals in the unreal.

              *Some esc's may or may not have been sent, do not need the no vision peeps assembling (read assemble, not manufacture) the majority of these thinking trade secrets are being stolen as they were not*

              All had faulty Fets in some state, including the new ones, no use of non film caps, all had insufficient heat sink capability, Programming was unidentifiable at source. (i told them the origin of one, the other two *cough*). None of the units sold here tested were manufactured in the usa, one was assembled here though, i couldnt find one that was all american made (i did tell him the one i preferred was made in Germany), either the programming was korean or chinese made or the parts were outsourced.

              I was pointed to an esc site that had some impressive units, sadly the one for my application weighed 6 pounds, the 3 pound unit was the equiv of schulze's 40.160. I pointed out weight as an issue, but it was bulletproof. In the end ********** stated they would like to make money on this but it would take a few million in just R&D to make "Bulletproof" esc's for our hobby in the sizes we need.

              They did state these things, fets need to be tested before assembly because of the manufacturing proccess, they are made in mass quantity like candy and dropped into bins willy nilly (not my words), Film caps need to be used, sadly these things run like 20 bucks or more in some cases, one reason the current esc assemblers dont use them i would imagine. larger heatsinks for low to midrange operation and proper programming. (they did not elaborate on "proper programming".)

              The summary from them was this, what we have now seems to be working in some regards and until someone with big cash knocks on the door nothing spectacular will happen with current esc types in the near future.

                  I say go for it. But I would suggest adding a cap bank for a little extra security.

                      Maybe Bob Novak is making Marine ESCs with Bill, you never know..
