Thanks mate, that gives me a bit to work off, I have searched for boat weights for hours and can't find much, the same as trying to see how it should sit in the water, all pic's and video are either dry or going flat out.
Millzee,
I appreciate the thread and pictures. It's been a big help in knowing where to go with my build. Please keep it up!
Thanks mate, I'm glad someone is interested, just be careful though, I'm not the person to get advice from, when I started this thread I was hoping the experienced boaters would chime in and help me out. Good luck with your build, I'll keep an eye out.
I would not worry about the weight at all. My 31" Rico probably weighs that much. A 35" mono running 2p is going to have some weight to it. You're going to want it too.

Millzee, go with aluminum tubing, it will flow better, its just as light, it wont split and you can bend it.....Also I hightly recomend puting some octura thrust washers between your stinger strut and drive dog ( 3/8 O.D. size).....Keep in mind when your drive shaft is under a load your cable will shrink slightly, the thrust washers will prevent the drive dog from diging into your strut.....Also keep in mind that the gap between your drive dog and strut is going to transfer allmost 100% of thrust up your shaft to your motor( causing heat buildup , friction and xtra drag) and also your motors angle plays a roll in handling when thrusting with shaft because thrust is determined by the motors angle...I setup my boats to thrust with the strut and I must use thrust washers. My opinion is the thrusting point on the strut or transom = equals a better balanced and better handling boat , this is only my opinion and this could draw some contriversary :)....If you decide to go this route keep in mind that you will still need a slight gap, about the thickness of a thumb nail or a single thrust washer...

thanks, I'll get some aluminum tube, a very funny (but dumb) thing I just did was burn out my specktrum 590 steering servo, I was goining out to calibrate the esc and I thought I'd check signal and so forth b4 I entered into the process and while wiggling the steering the servo seemed to be playing up, without looking at too much I give a couple of full lock turns only for the servo to lock back the other way and smoke started pouring out the top.After unplugging the rx battery I realised the rudder was sitting hard up against the boat stand which the pissy 590 servo obviously couldn't handle the pressure I guess I get to buy a new servo after all, I have a couple of Hitec ht7955's in my truck so I think I'll pinch one of those and replace it when I get the urge to drive it again. that sucker will handle a 7.4 lipo so I'll save some weight there by swapping out the rx batteries, that'll give me over 350 oz torque, that'll nearly bend the rudder if I'm dumb enough to do that again. Or do you think I should just get the traxass high torque waterproof servo?
I just bought 4 Hi-Tec 5645 servo's used...They are around $60 new appiece..168oz on 6v...They are strong enouph to handle my quad drive 43'' Conquest...If you want one I can give you one for $30 + ship..

thanks for the offer but it's too late, just got of the phone, I have both carbon and aluminium tube, a ht7955, 3/8 thrust bearing and some velcro straps arriving tomorrow, thought I'd put in a bit of local support and get shafted again.
Dam ! You don't mess around !...lol.....Sounds like you are going to be in the water one way or the other ! ....You must be on the other side of the world to be getting parts at this time

I'm in Australia, I had to rush the call to get it done by 5.30pm
Well I've finally calibrated and programed the esc, I gave it a very quick (10sec) dry run just touching the throttle and all went well except the motor was spinning clockwise, so I swapped a couple of motor leads and then tested for about 30sec with the throttle just in a fraction and a couple of 1/4 bursts, all good, well if you don't count the smoking servo from my earlier stupidity
Tomorrow when the gear gets here I will lighten it up a tad by switching out the water line tubes, replace the servo, add the battery straps and I guess I just have to make up a parallel lead, charge the batteries and select a prop, at the moment I only have two balanced and sharpened props, a x445 and a x450, should I give it a burl with the x445 or wait until I either sharpen and balance a x440 / 442 or get myself a few M series?(is it hard to knock of the tongue off on a x series, remember this question is comming from a bloke that had to buy a sharpened and balanced prop just to see what they look like)
I made up some cowl locks today, had to just use what I had, I hope they work, I can't see why they won't. The bloke I ordered the thrust washers from has sent me 1/8 teflon washers, they fit well on the shaft altough they stick out past the width of the stinger shaft, I asume shaving back the od of the teflon washers back down to the same diameter as the stinger od? This will be ok won't it?
Here's a few pic's of my shabby cowl lock's.
