50" Hydro Build

[TotalPackage]

Id like to see you try maybe a octura 1667 on that boat with that strong motor.I youre gonna get a gas prop why not try a cnc like in the photo ?BUT I think 184 amp average is quite healthy for a hydro so id trim with the prop in your wot run first (air it out) before I move on to another prop. Need to get you an eagle tree or something to give you real time data.

Complete Failure!

The 1460 couldn't even get it on plane..............went 25 and plowed, i quit after a minute or so of trying. The Prather 270 seems good to me now.'

I pm'd Dasboata and he is thinking about what to throw on it, i told him about the 6717/3 and he said he thought it was too big................we'll see what he comes up with.

Hmm i dont think the 6717/3 prop is too big for 10 hp.Did you tell him what power your motors are capable of ?.Its smaller than the 270,ok has an extra blade but id bet any money it will make that boat fly.

[old guy]

my first pic was the 6518/3 and then up from there 6717/3 the 6518/3 is a lot smaller than that 270 yes make sure he knows the power of the motor becouse we swing them in or gas boats with 6hp and you said on 10S you should be around 10HP

Rick, he actually suggested a 6518/3, i asked him if it was enough diameter......i just sent the pm so he hasnt had time to get it..........does the third blade help in place of diameter??

[old guy]

the size of these blades are way smaller than a 270 not sure how to say this but they are narrower in size so they are not just smaller in Diameter. go to voodoopropellers.com and have a look at one and have your 270 in your hand. you will see what I mean. they are a good prop I have like 6 of them no you cant have one just think on a hydro at say 17500 they get 65 to 70 out of one not shure the RPM you get on 10S but if it's more that boat is going to fly you will need to take it up slow to make sure it's trimed. water at this speed is hard and will brake that boat. Trust me I know hope this helps

Thanks Rick.................are you building a boat with a 2028..........???

The problem with the 10HP motors is the amp spike I tried a 1967/3 blade with the large Little screamer with a KV of 500rpm and I blew my 40.160 Schultz said I was pulling 300 amps for way too long like 3 seconds. It cost me $425 smackers! What we need is bigger motors with the possibility of 17,000 to 20,000RPM under load and a amp draw of 90.

Randy, what is your max speed you have attained?

Randy, what is your max speed you have attained?

62 MPH sofar with the smaller motor. I put in a 2230 1Y to go faster. I ran my 1973 Miss Budweiser at 70MPH with a 3040 8T

10s2p run

Ok, while i am dragging my feet on my new prop (which i am getting) Im still running and trying different stuff......what i found on 10s2p:

Only 4 mph faster
Changed the weight distrubution a tad............not as steady at speed
Temps on ESC 10 degrees higher at 148*
Motor 1 degree higher at 118*
Nose trying to lift a fair amount
Not worth it.........the 3 blade "lifter" prop on 9s should be the sweet spot
Sounds better though!
