    I have a couple pairs of CR props...
    Of course the 32 & 36 Venom Props
    and carbon Graupner 40's and 45's.

    I doubt I'll get to the 45's, but good to try. We'll see.

      Picked up some white appliance epoxy paint. I was planning on starting with a white base coat this time already, so worked out good.

      Still haven't decided on the color scheme. I have two tones of blue though that might work out well together. I've been thinking about adding in a bright yellow... but still unsure. Maybe I'll draw a mock up and color it in to see. No hurry on this one, so why not. Maybe take some time for a computer generated enhanced photo.

          Or one sceramer on 14s two would be overkill kill @20kw.alot of weight too. I think we sometimes forget about hp to weight ratio.Im sure a lighter twin setup will give u less stress if i was going the scorpion route id go 4035 800's @9kw thats plenty but here again what are your battery requirements . People would tell you no ;but I had one 17xl kb45 700 loved this boat and thought many times of buying another kb and running twins in your exact boat. They cost 40.00 . Some on here have had bad experiences and some have had really good.Now some that had bad had wrong setups too. I asked all the questions to find out.Now the one I had pushed my 43 inch 12.5 lb circus hull between 30-35 on 9s on 9s! No water cooling 1p. Now anyone with sense should be able to estimate 2 on 12 s come on. They can push a 450 @ 12s under 150 amps so keep hatin on the kb if you want.They complain about heat,high current draw,bad balancing I experienced none of the above; but look at the physical construction of the motors like the feigao and kb compared to say a pletti,neu,or lehner. Forget even trying to go deep; lets just stay basic. The cans on the chinese motors have no cooling vents .Add some.The wires on the chinese motors are typically longer and smaller.If you cant replace them with bigger (on some inrunners that might be challenging;outrunners not so much) cut them shorter and add better connectors.As far as the balance the new kb's come with high quality american, yes american bearings.If that were a problem;change the bearings. Lastly youre gonna water cool it ,you can fan cool it,and you can peltier cool it. Its all hype to me dawg You wont even need all that crap.Lastly if they pull alot of usable amps with a kv of 700 they should be torque monsters.Oh let me add the esc was a turnigy 80 hv buth think about it its rate 180 10 second amp burst 10 full seconds count it out thats a good bit of time. If you pull more than probably 120-130 amps continuous on the kb its probably over-propped.To keep from burning you truly need data logging on anything.

              Ive seen that vid footage and yeah he really does have a small light setup pushing that boat pretty well. 45-55 is good speed though.

                I would be concerned about those castle motors overpowering the 4mm hardware.

                    Yeah, me too. I have a backup plan. 4mm 078 wire drives.

                    Jeff has me addicted to the wire drives. No left right BS and they seem indestructible.

                    Tiqueman was explaining earlier in another thread about the benefit of the epoxy bond to the gelcoat. Basically using it as a primer to help prevent chipping. Sand it and "anything will stick to it". See my Generic 32" cat thread for details.

                      Ahh yes! Wire drives! I just installed a set on the ekos a couple of days ago. Have'nt run it yet but the props spin sooo smoothly!

                        OK, so I said WTF and ordered TWIN Little Screamers, TWIN Monster 200's and 6 - 6-cell lipo packs (12s/3p).

                        This mutha is gunna haul. No more power worries.

                              Nice
                              All great gear except the monsters......I would have waited for the swordfish for two reasons
                              #1- the reviews are horrible on the esc's and no warrantee
                              #2- swordfish handles More amps and you get OSE service

                              Yes you have to wait for the swordfish to get in stock but you have a lot of work ahead of you to rig the boat and paint before u need the esc

                              Jmho of course
