    Went through the thread again and I don't see any mention of a thrust bearing. Was one being used on this setup? It still shouldn't have happened, but I'm wondering if there was a bearing or not.

      I'm new to boat's but you already know that lol you helped me build my cheetah, thanks again. I think I just got a bad one out of the batch, boat was running awesome before this happened. I should have went with the motor you mentioned in the beginning, oh well learn the hard way lol

        I'm guessing the same thing I have read alot of good things about the motors thats why I bought one.

          Sorry forgot to mention that, I was running a MBP Collet but no thrust washer. Should I be running some?

                  Yea, his runs really good. I think a cheetah really needs a 1527 tho. Or a 4070 tp. If you go the cheaper route.

                    I think i will wait to see what happens my cheetah was running really fast with the TP 4060 1720kv i was happy with the performance, but if they send me a new one back i might sell it and get a 1527, i recently bought a castle 2028 for my challenger 48 build i'm really happy with the quality of that motor as well, a german guy on another thread said that the v2 tp motors have had al ot of these problems with the shaft and that the older ones were ok here is the thread i posted on that forum http://www.rcgroups.com/forums/showthread.php?t=2386172

                      Sooo... this is not good! If TP are saying (and it would be great if someone from TP can confirm) that their motors are no longer suitable for boats then I guess it's back to Leopards. From an engineering standpoint, an electric motor should be able to be stalled without the rotor spinning on the shaft. If TP have been manufacturing a product that would mechanically fail a simple stall test then they need to rethink what they are doing!

                      Shame, shame, shame on them!

                      Most companies that have good products work on improving the product, even if it costs a little more, consumers will pay for good products. Sack the idiot that came up with that plan, get it right and care for your customers, or refund them their money in full!!

                        I just emailed to power usa with a link to this thread. Hopefully they will clear some of this up and take care of the op. I don't see why they wouldn't.

                          No mention if thrust bearing is used or not, my guess is that it wasn't used. That should have no bearing ( no pun intended) on this issue.

                            This would surprise me. Especially with the commitment that some have made to their products of late. I know we're just a spec of the market but still.

                            Plus, I'm pretty sure the guy that runs TP is a boat racer himself. He's going to produce products he can't endorse? Not likely. I'm inclined to not believe this "not for boats" claim until I hear it from them directly.

                              This is what I thought. ( have been having good experience with their 36xx motor)
                              Interesting to see what the Germans are saying, still, too early at this time to jump to conclusion. Hopefully someone will shed some light on this matter. One thing is for sure, they have changed and I wish they had held onto their older version.
                              If ( and I am pretty sure it is) this is a cost cutting measure to change to the present version, then TP is not alone, it is a global practice.
