    Nate,

    Most heat racing riggers have the right side sponson with more inclination than the left. So this could be intentional. For SAW boats, symmetry is usually better.

      Nate.
      While you are waiting for parts, I strongly suggest you beef up the rudder bracket, turn fin, & boom sleeve attachments in the sponsons. Something similar to those in the link I posted previously in post #13. They will fail. Also the booms.

      See the danger. THEN DO IT ANYWAY!!!

        Thanks bud, I did not know this, but it makes perfect sense, learning something everyday! I actually stayed up pretty late last night thinking of a simple way to level them, the only simple way to get them level, was to adjust one side of the carbon skid to get the desired ride pad height on the sponson, tighten it, the twist the other sponson in the opposite direction, then tighten it. Seemed easy, but.. without laying it on a flat surface, it was hard to get any other certain adjustment, aligned properly.

        Yes, I going to get started pretty soon, I have a 2-4 week wait on the custom lehner motor, and I have not purchased the ESC yet, I can't quiet decide between the YGE, or Hifei model esc's.

        As I am not local to any oval racing, Im not very interested in doing anything but straight away passes. So if you guys didn't see this just by the picture, notice the length between the hull and sponsons? The shorter the carbon rods are, the more strength and less flex. Figured I would try this. BTW, one of the props came in, an M440. The turn fin and bracket I will replace, thinking on the idea of using a carbon fiber panel to cut out the bracket, and epoxy/resin it to the sponson.

          I cut down 5" off of both carbon rod, there is 172-1/2mm (6.7") between the hull and sponson's.

            Update. Waiting on a custom ordered Lehner motor is a wait and a half huh. Cut down 50mm 1/4 brass tubing for carbon rods, added strength!

              I've seen both Posseiden and Krabs sponsons ripped apart by buoy strikes and boats "rubbing" I wouldn't reinforce the rods myself, replacing rods adds no weight and is a lot less messy than epoxying sponsons back together.

                Agreed, you want the rods to be the weak point to give in a crash. Make the hollow tubes in the tub and sponsons robust, but leave the booms to break. Otherwise you run the risk of ripping a sponson apart or worse yet a tub.

                  Nate, here are some pictures of my Mr. Krabs. I hand built all the CF parts for the strut, rudder, turn fin, motor mount and battery mounts. CF is the way to go! I will convert to 6s this fall. Allen

                    Just a note of caution Nate, the boats I mentioned running 6s 4500mAh are all running in the Naviga Hydro2 class which calls for a battery that is under 560grams, the 6s 4500 cells we use are low C cells usually 20C though some are now up to a stated 30C (probably BS, our old 20C cells tested to 14C), and the dr super evil was designed around them, my 6s 4500mAh hydro2 packs are a bout the same volume, a little longer but a fair bit shallower than a typical high C 4s 5000mAh pack, so if you are buying High C 6s packs for your SAWs runs you may well not be able to fit in as much capacity as we race with, double check battery dimensions with the space you have before purchasing, maybe making a cardboard dummy of a potential pack to try for fit.

                      The lipo is that last thing on my list to order. I have thought about which lipo will fit snug. Im hoping my lehner motor shows up early this coming week. This will show me how much room I am left with after mounting. I talked to my local Hobby shop owner, we are going to take out a few boxed 6s lipos and see what will be the perfect fit.

                      I will only be running the boat for my own enjoyment, no racing.

                      Im looking at the flight power eon 50c 6s 5000mah, sitting side-ways in the hull might work. I will hopefully know soon! When I get everything ready I will report back with pictures for you guys!

                          Had two 2s 5000mah hard packs laying around, figured I'd see how much space a 4s configuration would take up. Here's a few pics. Also, one question, I have only begun once in laying carbon fiber inlay in a hull, and never finished before I sold the hull, how much room will the carbon fiber and resin take up in the hull seeing its a good layer..will this effect anything?
