    I will hold off on ordering until I make a run on the x447/2s, if I do get them should I do br or ss? Its two Sirius on the outside and a CC in the center. All swordfish ESCs but the center one is just a newer version from Keith. I may be able to up the size of the batteries to 4000 mah possibly, outer ones for sure, I think they can fit in the center as well. The nose is filled with resin and cloth to about an inch back in the center. I plan to router out from the top of each sponson in a triangle shape to the point where it's still sealed and then use a piece of foam and lead if needed to weight it back if needed and use CF plate removable of course to seal it back. Will post pics if and when I do.

        SS for high RPM and BR if you care to modify them. I don't think the SS cup or anything too easily.

            Probably just go SS. Well I went to do that trial run and it's funny how everything can power up at home and then when you get there something has to go wrong, one motor just pulsed so no go, try again on the weekend I hope, gotta figure out what the problem is, maybe reprogram the ESCs. Go from there.

                Did one of the ESCs get wet?

                If you want a propshop prop with more speed potential than the octura x447, 4518/3s would be the natural choice, but it's a very big step up, so be prepared for it. 5017s are too large in my opinion. Either way you should plan on moving the drives up. Just as a disclaimer, I'm not recommending these as something that won't cause a problem...that's a lot of prop to spin with such little battery. I'm just factoring the prop relative to the hull, not considering power.

                    Didn't even get it in the water, I had problems with the Both pulsing before and I had to reprogram ESCs, hopefully it will fix the problem. Well I will wait until I get a run on the x447s then go from there but I am looking speed for sure. Did I mention the boat fully loaded is 19lbs.

                        Well I hooked everything back up without doing anything at all and it powered up all three fine. Guess it was a sign.
