I'm going to try something very similar and will follow this with a lot of interest. Going to take me more than a few weeks but I'll be going to the shootout with or without a boat to race. I was going to convert the segad in my avatar but I'm going to try an aeromarine hull instead. Good looking hull btw. Mike

If we get good water for the run the speeds will go up over last year. I think a larger cat is the way to go..40+" with twins. 8S. They only hit about 60 mph last yr.

I may have one there or I will be building one with a local down there to put the heat on the gas boys....they won't even come close...LOL.

I would think Castle would like to be involved! Joe????

Ill be bringing my 37" triple down to boogie with the fuelers.

Did a little modding to the gas tank area. It now fits four 3s 5000's perfectly by removing just a few pieces of ply. The other two 5000's will go up in front of it.

Also did some epoxy reinforcing to the stringers and on some areas that didnt have much or any epoxy at all.

Added a bit a bling with some striping.............

???

Curious as to how much the hull and hardware weigh and projected rtr wt. Should be good baseline nfo. thx Mike

[Make-a-Wake]

Any suggestions for a prop on 9s2p.................i'm a bit apprehensive of just running it right off the bat with the big 66mm..................has some pretty good pitch.

Should i start with an X series...........55-60-mm...............?????

Thanks

[madgadget]

Should i start with an X series...........55-60-mm...............?????

x 655 de tounged to start imo

[Make-a-Wake]

Thanks madgadget, all i have at the moment in the "range" are an x450, an x460, and the stock 1.4 x 78mm cut down to a 66mm. May try the x460 first.............

Still trying to accumulate all the electronics, the SF240hv should be here in the next day or two along with servo's, 8mm bullets, couplers etc................

[madgadget]

How much?

Are you going to let me know how much the hull and hardware weigh? It will go a long way to helping me decide my setup. 1p or 2p HV or LV etc. thanks,
Mike

[Make-a-Wake]

Sorry for the Late reply..............had to find a way to weigh it. Hull with only hardware weighs 11.6 pounds.............kinda suprised me. Im gonna have a 3 lb. motor and 6 pounds worth of batts in it............whew!

Motor should be in Saturday along with the SF240hv. In the meantime i went ahead and made a beefy RX pack out of an older 6 cell sub C pack. It should do the job as i will have twin Traxxas 2056 servo's.

[old guy]

I would like to know where the C/G is when you are done RTR

[TotalPackage]

I might step down to 8 s bring the rpm down a bit and try a 457 460 just a thought maybe even down to 6 s 2p and a gas prop . Never did it just sounds better for that big hull.I know we all talk about weight alot but as fast as people are running now I think u need some weight . The only advatage I see to a light hull is you can put the weight where u want it.Thats under 20 pounds so its not too heavy I dont think.

[Make-a-Wake]

Thanks guys, I'm figuring right at about 22 lbs with everything.............. a delivery attempt was made today while i was at work Another day to get the goods.......... The motor may arrive tomorrow as well................man, i wanna get some stuff in this beast.............tired of just staring at it!

I could try 8s with a 3s x 3s x 2s, never thought of that.........i have the matching 5000 40c's of each. I have to get the x460 bored out to 5mm........just takes a hair more but dont want to do it myself and get it off center, think i'll run it by a tool and die shop i have used for shaft work before and slip 'em 5 bucks.

I dont have a data logger, and those i have seen are good up to 100 amps, i want this thing to pull right in the 180a range and need to see what certain props will do instead of the old "hold full throttle and see if the speedo blows" method. 180 amps should give me about 8 horsepower on 9s. So i may start with the x460. Since no logger, i may have to go by the seat of my pants.
