    ML Boatworks 1/8th Scale 171 Extreme Build Miss Elam

    Well I had so much fun with my smaller UL-1 this past summer that I just had to look into a bigger boat that I could build into a fast electric for racing this next summer. Talked with Mike from ML Boatworks quite a bit and decided to go with the 1/8 scale 171 Extreme kit the Miss Elam boat.

    Now I have been an airplane builder for quite some time....since I was 15 when my dad and I would spend hours in the basement working on models. No servos then...just escapements....LOL. But this is my first try at building boats, especially an Unlimited Hydroplane. I will also be posting this build in another forum and I'll try my best to keep up with both of them.

    In any case I will be looking for a lot of ideas and information from anyone that would like to chime in. OH....and I take the negative criticism too....as long as your nice about it....LOL I don't think of there ever being a dumb question, except for those we don't ask. So if some question sounds a little on the dumb side, bear with me. Remember I’m new to boats and want to learn more.

    What I'm planning for power with this boat after talking with Mike at ML Boats is the NUE 1527 1Y on 8S. 10S if they will fit. But I'm thinking for a racing profile that 8S is going to be more than enough. Not sure on the ESC as yet, but thinking it’s going to have to be at least a 240amp. Was going to get more ideas from you folks on that. Also the running hardware from Accu-Tech seems to be the way most folks are going. Again any other ideas or suggestions out there are welcome. Ordered the cowl from RC Boats and the Wing set from Phil Thomas last week....so expecting them soon.

    I have been reading up on the rules for these boats, but as we all know sometimes there are ones we might have missed. So if you know of ones that seem to keep coming back and biting guys please let me know. I think the biggest one that I have seen is that the drive dog cannot extend past the transom, so that means a thru hull drive shaft support. Appreciate your ideas of the size drive cable and stuffing tube to be used. Was thinking of the 1/4" reduced to 3/16.

    Well I got started on this over this past weekend and pretty much have the center section done. Nice thing about this kit is that it builds pretty much in 3 separate sections. If you have a flat surface to work from, that’s about all you'll need to build a nice straight and square boat frame with this kit. Everything is perfectly laser cut, best I've ever seen. And everything fits perfect. The next thing to move onto will be the sponsons which should go fairly quick. When I ordered the kit I also ordered all the 1/4X1/4 and 3/16X3/16 square stock, plus all the sheeting for the boat from Mike.

    I've attached some build photos from this past weekend. Pretty much started off by tacking everything together with thin CA and Med CA. The hull bottom sheet is all one piece. I thinned some 30 min epoxy and applied it to all the bulkheads and hull stringers and then positioned the hull bottom sheeting. Weight down and wait. At the same time I went over all the other joints with the thinned epoxy mix for a better bond with formers and stringers. I'll be coating them again later when I get ready to coat the inside of the boat.
    Any suggestions are appreciated on what your using for sealing your boats....West System...etc.

    Thanks All! Can't wait to get it on the water this spring. It’s all Ice right now...LOL

      You'll enjoy that hull, I've been running that same boat with great success. For motor choices a 1527 1Y will be best on 8S, for 10S go with a 1527 1.5Y (this combo provides excellent results). The ETTI 220 OPTI PRO ESC has been working great for the scales, a bit of a pain to program but once past that a rock solid ESC (USE THE CAP BANK THAT COMES WITH IT!!!). You want the 8mm shaft option in either motor you choose and use the 1/4" step to 3/16" cable for sure.

        Different ML hull but with the 1.5Y motor on 10s, also using the ETTI 220 OPTI PRO ESC with cooling tube mod.

        Looking forward to the rest of your build.

        Keep up the good work!

          The 1527/1y is too much for an oval racer on 10s. I set sport hydro SAW records in the 80s with that motor on 8S with amp draws well under 200. You don't need 35,000-plus rpm to oval race a 1/10 hull.

            Thanks for the information Doug....Seems that is the going setup for these boats. The Squire Shop sure seems to do well on that package and very, very stable; not to speak of a real pretty boat....Nice Job!!. It would be great to see some build pictures of motor location and batteries to see how it all fit in your boat if that possible. Thanks again Doug!!
            Might be more questions down the line, hope you don't mind.

            Mike

              You're right Jay. Don recommended 8s on the 1y.

              Mike I can't take credit on the hull build and paint. I purchased the boat from Mike, had to have it when I saw it. I just rigged it.
              I'd be happy to post some pics if you'd like.

                I understand what your saying Fluid...I just want a good stable boat in race setup with speed to compete. Now this is an 1/8 scale...not a 1/10 and guys that have talked about the 1527 1.5Y on 10S are talking about 1/8 scale if that makes any difference. In any case I would think it's going to be plenty fast.

                  Evening Don,

                  Thanks very much for the information and boat choice.... Would be very interested in seeing any build pictures or links to your boat if possible. How is the race setup with 1527 1.5Y...Still a very stable boat?? The only reason I was looking at 8S was Mike indicated it may be very difficult to squeeze to 5S packs in the hull on top of maybe to much motor for that boat. But sure would like to hear your experience with that setup.

                  Appreciate anything you can share.

                  Mike

                    1527/1.5Y on 10s is a tried and true 1/8 scale setup. I have 2 Nat titles with this setup, and plenty of other wins.

                      3/16 cable is fine for pretty much any scale setup

                        That would be great Doug....

                        Just like to get an idea of battery and motor placement etc. So what ever you have would be outstanding. You can email it if you like.

                        Mike
