    Pursuit Coupler Stuck

    Hey, I know this has probably been asked before, but how do I get my coupler out which is stuck? I have the Pursuit boat, and the inner part of the 3 part coupler is really stuck onto the flex shaft. I think I read about heating it up, would that help?

      Guess I'll try that next. I should just get a better two-piece coupler.

      I've got the 4074 in it too, it's got a 3/16 flex drive in it. Great boat! With some more adjustments it'll be even better :)

          I first ran with a 40mm prop which came with my boat, and then tried the 42mm that came with it as well. I later realized that my strut wasn't neutral so that definitely slowed it down a bit. Also, I didn't leave enough room when I put on my flex shaft (I got the 1 piece upgrade shaft). Things got pretty hot that time.

          You should start with the x440, and get everything neutral. You should use 2 2s lipos and put one on each side as far back as possible. Once everything is set go for the x442.

            I think that if you find a small enough gear puller that will work as well (actually thats a great idea I dont know why I never went to search for one) But I had mine stuck recently, tried heating and pliers... nothing. Had to grind the sucker off. That wasn't fun

              I don't think I have a gear puller, haha. I may try to just use pliers to get it off, and if not then heat it. Guess I should've gotten that 2-piece in the first place

                Use a small screw driver and pry the prongs apart. It will then slide right apart. This is a common situation with the stainless steel couplers when they've been really tight.

                Can't recall which expands faster mild steel or stainless, but please be careful if trying to heat it.

                Hope this helps. =)

                  Be careful prying it off, I worry you'll damage the bearings. Try heating the coupler with a soldering iron, it will probably slide right off...
