42mm is a lot of prop for only a .12. Do you have any photos/videos?

Ryan

Hello All, Im looking to upgrade my nqd hydro boat and im woundering what do you think between the 500 sp race and the 600bb race graupner brushed motors? Im going to be using 2 motors so do you think the 600 will fit where the stock motors are ? Obviously ill have to make a new mount but im woundering about cutting out plastic?

Im looking for speed around 25 to 30 mph. and im not really wanting to go brushless just yet

thank you

1. Use a Graupner 700BB 8.4v
2. Use 12 cells.
3. Buy an appropriate ESC to handle ONE 700 motor. The Jeti Navy 700 works well
4. Set up One surface drive setup with a 42mm prop
5. Buy an appropriate hobby grade receiver.
6. Set up a rudder with a standard servo. Nothing is worse than vector thrust.
7. Get rid of the stock motors and especially the receiver/esc!

That's the best and easiest way to get 25mph without going brushless. What ever you do, get rid of the vector thrust.

Hey Crab,
I have (purchased) two NQD's so consider yourself lucky[].

I purchased a UL-125 real hydro... big difference..

Moppie...

I am about to go down this path myself as I enjoy cutting up boats and fitting unusual handmade hardware. Low cost and many hours spent is the recipe that I like.
I have read this thread from top to bottom and am quite keen to go with a single 700 on 12 cells and a straight shaft from the front to back to keep the angle as low as possible. I may even use 2 gears 1:1 to step the shaft down at the motor end to flatten the shaft angle.
My main question is where to place the prop.
Traditionally we seem to like the idea of aft of the transom and with the hub about level with the rear of the ride pads. Naturally there will be an element of down thrust that should assist with getting the bum up.
Please put up pics of the rear of your modded NQD hydro.
I am warming up the dremel now!

carefull the senior members here will tell u to take your peice of crap nqd elsewhere just like they did to me in the nqd high wind thread. they dont like the modding of cheap boats cuz its makes theyre $1000 plus boats look like junk. lol either way keep posting mods just to piss em off.


Ive got some motors and batteries laying around if anyones interested pm me.

EDITED FOR DELETED PREVIOuS POST

Simon,

I would consider picking up a Graupner 700 8.4v BB motor and a flex cable, .150 with 3/16 prop shaft over a straight shaft. Then use a 3/16" strut. The prop center line should be close to the bottom of the rear ride pads or even slightly below/above. You may angle the prop slight downwards. Start with an Octura X440. Water cool the can and brushes on the motor.

On 12 cells, you should be around 25mph.

Ryan

nothing was inflated, quit flamming my threads.

If you can't take the heat, do not start the fire.

Ryan

hey my high wind does 50 mph anyone wanna buy it!!!!>!>>>?????

Ryan
Thanks for the input. I will most likely end up with that setup after I have tinkered and played with a few other low-cost or even free-set ups. I have a box of cordless drill motors that I will play with and can make my own shaft/stuffing sets. Rudders etc are about an hour of cutting and filing. If I can get one of these hulls for a good price then i should be able to at least get it running half o.k for less than $50. I never count in the cost of esc, cells and radio gear as all of that is easily transferable to my other boats.

On another note it is very amusing to see some of the flaming that goes on. I personaly think that these modded boats should be kept here in the SE section as they are what may help some people get into FE. My wife would shoot me if payed $700+ for a '27 etc.
I like to tinker with and mod low cost boats and KNOW that they will NEVER run close to a BJ or 27. Those guys with the big fast boats have a LOT of knowledge and skill that I am here to tap into. If we all play nicely then we can all have fun.
Enough of that for now.

EDIT It looks like while I was typing Taylor was subtly pointing out the rules to someone above.

i think you need to review your agreement when you signed up on rcu.
you ARE NOT ALLOWED TO POST SELL OR WANT ADDS ON RCU

Simon,

On Tower Hobbies, I purchased a SuperVee 27 RTR for $140 on the scratch and dent section. After a few glass and stringer repairs and re-installing of the hardware it was a 35mph hull. After a prop change and tons of tuning it GPS'd at 39mph. This was not even close to 700+. It's much closer to the money you guys are spending in total on these NQD hulls.

My first SV27 was purchased at 180 and did not need any work to get going. There's plenty of cheap hobby grade boats to choose from.

Ryan

A few posts have been removed to get this thread back in a more positive direction.

Please consider the topic and thread direction before making remarks

Thanks guys

Not one to argue over prices of boats available in the U.S.
Over here a sv27 is $700, if i could have one for 2 or even 300 I would not be playing with the boats that I currently have.

Anyway back on topic now guys.

i like how my thread got deleted for no reason. i was on topic, how come taylor always comes into my threads to bash about cheap boats and never gets his crap deleted.?????

I just can't believe I found a site thats talking about doing the same thng that I'm going to do.You 've got it. The NQD hydro! I took mine apart so I coud repaint it and thought about updating things while it was in that state.By complete accident I googled NDQ and clicked on the first thing.I've read through this entire thread and am very impressed by wht I've read.I've come to one conclusion.Some of you have a lot of time on your hands.And some of you are bloody brilliant.It's hard to believe that as great as this boat
looks,it's got all these problems. And thats why we all put all of this time and energy into makeing it better.I'm glad to have met you all.

Awesome, now what are your plans as far as the hull is concerned. Are you looking for more speed?

Ryan

To be honest with you Iam a beginner.I have about 5 boats but I've never done what you guys have. My plans is to take
one of my NQD Admiral offshore cat's (I have two of them).Gut it of it's two 550 motors and of its electrics and transfer it into the hydro.After staring at it for hours last night I may be in over my head. But if I can do it,it will seriously boost the performance .The offshore cat in my estimation runs really strong. And if I can do what i plan on doing it'll be worth it.
The cat will get a couple of 700 motors and such later on.

hi Scott.

I think that the hydro'll be too heavy for the power you'll be getting from the stuff off the admiral. The admiral's a pretty cool hull (i think it's a clone of the kyosho lambo cat), but alas the hydro, for all its good looks isn't so good performance wise. It needs hobby-grade electrics and hardware to get it seriously moving....and that's where i gave up on my plans for the one i had. If you're on a budget i'd think of forgetting the hydro and investing in the admiral, but that's me. IF however you're hell bent on getting the thing seriously moving, i think your best bet is to invest in some hobby-grade stuff.

NQD also make a rigger that can be transformed into a pretty fast boat, and also the batboat copy they make isn't a bad hull....keep us posted about the admiral.

good luck!!!!

Andrew

well the 550's aren't going to work they set too high and won't let the body go back together.and i'll just put the admiral back together than try to adjust everything.looks like a job
for the 700. i think your right about the lambo on the admiral.right now i don't have that kind of money so i'll have to contemplate what my next move is.i was so hoping.NDQ should read this thread and take heed.

although no one else seems to be on here anymore,heres what i've done.to kep costs down i fownd a doaner boat with all the trimmins with a so-so hull.it's got two inline 550 motors and and the electrics should drop right in.i'm really looking forward to this. let's hear from you all. if your still playing with the thing that is.

Where did you get the motors from and hom much every thing without the boat.

Hello all !!

Just got the NQD Hydro free of a friend who actualy found it in the trash somewhere ! xD LOL
Well, as im only in to heli's at the moment, i tought it would be fun to do a boat buil.. ( as all my friends have one )

So, time to get some hardware for this thing...

I have read 10pages here now.. (taken hours) hehe, and got some ideas...
If i got this right, a 700 single engine is the way to go... right ?
I dont wanna spend to much money on this,about 200bucks +/-, but still wanna make the boat go about 40++km/h...

So whats the best setup to go with ?

anyone wanna point out some parts, and links to where i can get them, if so, that would be great !!

Thanks alot !
Btw, maaaany dead links (videos)

And great builds everyone !

Hello Dragon,
Don't want to burst your bubble - i really encourage you to take up boating, but it was in the trash for a reason. Really if you want the challenge of building up an NQD hydro try to do it on a 0$ budget (stuff you find lying about at home). For all the time, money and effort you're gonna spend on the hydro (and i guess after reading all that you've come to the conclusion that it involves a lot of input), and you'll get very little out of it. I'd save my 200 bucks...you might as well buy 20 x 10$ pizzas, eat a couple and use the rest as frisbees for sheer entertainment value or if you're really into models buy new batteries for your helis.

Or why not a decent RTR or ARTR. I've been in the hobby for a couple of years, and seriously this is probably one of the worst hulls i've seen. The plastic quality I can forgive, and even the words "sports game" on the side, i guess you can remove....but screwing the top and bottom halves using screws that go in at the bottom! IN A BOAT?

as soon as i finish my current project (rebuilding a hydro btw) i think i'm gonna run for world president and ban the words "sports game" from ever being printed on an RC toy again.

Good luck boating - it's addictive,
Stokes
