      How should the strut be adjusted? for example when should i move the angle up or down?

      When you angle the strut down, the front of the boat will drop down (up will lift the boat up)...How is the boat running? Flat? Bow up? down?

      As someone here suggested, you should try and set you tabs level with the bottom of the boat...for now...just get the boat planing the way you want it to run FIRST, then try some tab adjustments. Adjust ONE thing at a time with SMALL increment changes...

        In plastic I would go for a Y534p, if that works out OK an X435 is probably the way to go.
        I spun a x431p on 3000kv 3s on a 30A controller with 43A peaks average about 30A, an X632 was 56A for peaks and I didn't do enough testing with it to get an decent average as I didn't want to blow my 30A ESC, this was in an 18" 730g cat so your amperages will probably be higher despite the slightly lower KV. The X632 offered higher speed and better acceleration at speed but also a deterioration in the hole shot, which was no problem for my little cat but is not what you want so go with diameter instead of pitch.

          I have the same boat (running an Ammo 36-50- 2300 on 2 x 2s in series) and have just started to play with the setup. The boat came to me with a two blade prop and the trim tabs were down a bit plus the prop was angled down. The SuperVees put it to shame - even when I could get it to hook up.

          So far we have changed to the 3 blade SuperVee prop, brought the trim tabs up to neutral and angled the prop up a bit so she won't run quite as wet. Hooks up right away and throws a heck of a rooster tail now

          More work to be done in the set up.

          Where are you putting the batteries? They seem to need to be down the sides of the hull, on either side of the motor or else the hull runs too wet.

          Also, the tray that comes mounted in front of the motor seems to be a better place for the ESC than the batteries.

            I just want to give my input on your boat MM.....its a fantastic and proven contender.....lots of guys have had great success with that hull....when you get things ironed out you will love it

            when you mentioned "squared end"....are you talking about the prop shaft where the squared end flex plugs into it?.....if so I was thinking that should be soldered or jb welded somehow....but i don't know..I have almost the same boat I am building and need to know this also

            also if that is the same flex and prop shaft I have..the prop end of that prop shaft has no threads and the bullet is just held on with a grub screw...seems like a problem spot to watch out for

Also we were having issues getting more speed out of a DF29 so when Ken (KSM2001) REMOVED the tabs altogether his gain was almost 20 more miles per hour with a slightly larger prop . Ken is getting 57mph out of his DF29

              Peter do you have a picture of a propper starting point for turn fins....I have mine angles back a little bit...should they be way back?

                  I have the same boat. My set-up is 3S 6500 30C, cc hydro 120, Medusa 028-056-2800V2, Octura X440. My boat puts the supervee to shame and the Miss Elam also (nether boat can catch it)! Temps are a little high for my liken so I'm going to prop down one size to X438. My strut is all the way up and trim tabs are at neutral. Once you get a better motor she will get all the way out the water and still handle a 100 times better than the supervee. What batteries are using. I also have my batteries in front of the motor I need the weight up there.

                    Well i am running two 3s 2200 25c lipos in parrellel on either side of the motor. Right now i have my trim tabs flat with the bottom of the boat, the turn fins are swept back a bit, and i have the strut angled up a bit. Eventually i plan on changing the motor, and i want to go to a piano wire drive.

                          Is there any binding on the driveline? When I first got mine I had sand the strut smooth (knock the paint off) so it would turn smoothly and grease everything. Have tried to stack the batteries up front? Post some pic's of the inside. Sorry hotwater just trying to help out.

                              Well i have not tried to move the batteries much, because i had them set so the boat is almost perfectly balanced front to back. And i have not noticed any binding, and i lubed up everything.

                              For some reason i am having trouble with pics, i will get them up later.

                                Here some vid of mine with the stock FSD motor and stock prop (S&B). I had the 3S 6500 mAh 30C and cc hydro 120 esc in there. I get around 9 min. of run time.
