    Nicely done!

    Now reinforce the motor mount so it doesn't crack the hull. =)
    If you push on the motor you will see that the hull bottom flexes between the motor and the sponson. This is where it cracks. After what I saw yesterday, it's pretty much a guarantee that it will crack.

    I just used some fiberglass strips and laid them between the mount and the sponson to stiffen the area up. We'll see how it works.

    Again, very well done! I love those T180 ESC's. They can pull enough current to melt Castle 6.5mm bullets on the motor side. Cool stuff. That should be a rock solid setup if the motor doesn't overheat. =)

        I like to epoxy a piece of 3/16 ply down and even wider to disperse the weight to the sponson tunnels but that was on ABS hulls...my MM has it as well.

          thanks! yea for sure i will reinforced the motor mount better after seeing them crack.

          was kinda disappointed about how big the esc was but hope its worth the money. programming it is abit tricky w/o using the programmer they make but got it down quick using the manual n transmitter.

          wow! really they melt 6.5mm bullets? crap!! im using 4mm bullets come stock with the motor. i guess ill give em a try see wat happens.

            ESC is overkill but, I like that.

            They come programmed properly just setup your throttle & go. The Defaults & auto settings work well I find.

                The T180 has been the most reliable ESC I've owned, although you might consider an external BEC. Less heat created in the ESC. Surprisingly the BEC creates quite a bit of heat.

                The melting is from very high amp setups, I think you'll be ok in this little hull.

                Looks like you've replaced the stock servo. If not, watch out, it overheated a BEC on me and melted the ESC trying to center itself on the bench.

                  ...and people think I'm a bit nutty for NOT using on board BEC...??? This is good to learn early.

                    Yeah, I thought so, until I started learning about heat dissipation on a sealed compartment. The BEC isn't water cooled and tends to get hot under normal use... if over loaded... well... you know the drill. Sucks to loose an $80 ESC because its BEC was overloaded.

                    I now factor it in to each project. I'd rather lose a $15 BEC and have separate heat to worry about.

                      yea replaced the stock servo when i got the boat. hate using no name brand servos they tend to tweak alot so i slapped on a nano futaba s9550 frm my tc5.

                      looks like ill be using my castle bec then!

                      oh by the way when you reinforced the motor mount, did you use epoxy or resin?

                        I used actual fiberglass bondo resin. I would imagine a good epoxy wold reinforce the area as well. Just not sure how permanent the bond would be.

                          Well I think I am going to give up on the surge flusher for now.
                          I took it out to the lake this morning and the drive shaft fell out along with my new metal prop. guess I should have tightened the nut on the shaft hanger better.

                              Laddie, you have some real problems with the drivetrain, your bare flex drive connection at the motor is way too long prior to the stuffing tube and you left no clearance between the drivedog and the strut. My 2 cents.

                                really?? because it works just fine! incase you didnt know the whole drive system is modded and shaft rides on ceramic bearing. there is a gap but aint much but its there.
