Hi - Got my ESC prog-card USB link and set up ESC for correct cut-off for the li-pos (3.2 V per cell) but managed to blow the crappy drive train (3rd picture) - I always figured it had to be up-graded - The motor shaft is 4 mm and a 4 mm straight steel shaft down to the prop (shown 1st pic) - I have one of these (2nd pic) coming in but I believe alignment is critical for all to work well - Any suggestions - It blew when I was checking to see if the prop spun the right way (which it does'nt) - How do I fix that ? - Thanks All -

just switch 2 wires on the motor and it will spin the right way

Before you ask WHICH two....dosen't matter. ANY two.

OK - No problem with switching wires - motor spins counter clockwise now - Any great ideas on how to get this drive set-up so it's dependable - Thanks

DON'T run it with the coupler installed as in the picture! It will most likely hit you in the eye..., or blow a hole in the hull.
The allignment must be near to perfect with this kind of coupler!

Thanks Man - LOL - Now you tell me - I was setting up my ESC and the motor screamed up to full RPM when the plastic drive dog broke and put a nice dent in the ceiling where it hit - Lucky I was not watching too closely - No wonder that boat is now out of production although it did come with a smaller motor originally. The motor is an Xpower B28 with a 4 mm shaft - I am trying to fix up a wire drive for it - Thanks

OK - I just checked and sure enough that plastic coupler/drive dog (piece of junk) bounced off the bottom of the hull when it broke - The hull is still sound although the paint chipped off a bit on the bottom - Should I put a drop of Xpoxy Finishing Resin and sand it down good - or what is recommended - Thanks - Steve

You will have more scratches than that after you get it on the water but you could use just a drop of ca glue for now
