    Will they bothe fit in the middle ? If you are building a drag boat my thinking is having your prop wash in the middle and a rudder in the middle in the wash will help the boat ride more level when eccelerating hard........I can build a double motor mount for thoughs as long as there is a extra 3/4'' of room between the rails .....

        For installing the motors: As said cut down the rails or maybe completely remove them in that area. Second thing is, you may cut down the "frame" where the hatch lays on. This should give you another 5-10mm and then I don't see a problem to put the motors in the sponson.

        For the motor mount itself: I'd make a mock-up out of cardboard and then cut it out from a 3mm CFK sheet and fix it with some resin as well as some glass-fibre clothe for reinforcement. As the engines are quite long as well as heavy I'd absolutely recommend a rear support like the "Aufschwinghalterungen" from LMT.

        For the setup: I assume 2x 10S and Swordfish 240HV here from OSE?

        Do you want to use Powertrimms or Struts?

        Best regards,
        Manuel

          yes 10s and I am considering the SF esc from Steve I might just order another boat with 1/8 X 6" rails Putting the motors in the tunnel will make life much easier and pretty sure I will have Peter build me a mount thanks Chris

                    just 35" and 2x 2028 as well as 2x 10S Lipo? I think thats just too much as well as being too heavy. But curious to see the results.

                        Wow Chris I didn't know the hull was only 35"! I thought you were building a 45" + cat. Thats a lot of power for that little hull.

                        But I guess you want 100 MPH. You should have no problem getting that speed, keeping the boat in the water will be your problem. It will be fun to see.

                              Yes sir, get a bigger boat!!!
                              You can break that 35"er with a lot less motor(s) LOL

                              ScarabChris, If you used clutches and ran for 30 min you were never a gas boater. LOL

                                Hey man I resemble that remark!

                                I was always a sport RC boater. I only raced a few times and guess what I won once. And I won against much faster clutchless boats. But I won because my boat came back under its own power. Steady along at 45-50 MPH with the 60+ MPH boats blowing past mine, then blowing over. You can't win a race if you don't finish it. LOL.

                                I have always been a scale fan so sometimes I likes just letting the boat idle around so I could watch the water blowing out the exhaust pipes. Plus I liked just giving the boat a slight push off the shore instead of throwing them in.

                                Hey Chris, take a look at the MHZ mystic cat hulls. They make a sweet 45" hull. Thats what I was going to build then I changed my mind at the last minute to the 54 Fountain. Those big motors in a 45" MHZ Mystic should get you close to 90.
