Well, the boat got here today, first thing I wanted to do, rediculous as it seems, is to mic the boat out, see if its square, run the laser down the bottom, look for hooks, etc.

The nqd is pretty much junk as far as consistant dimensions go, so, I wanted to see what I had here.

My personal background is a masters in mechanical engineering, so dimensions, machining, thought patterns to a end product, are VERY important to me.

First impressions after opening the box was the EXTENT he goes to to provide for every detail..individual packages, sealed, for all the accsy's,
finish on the plastic hull, deck, and hatch, OFF THE HOOK.

The CNC cut outs in the hull are flawless, no sharp edges, no flashing. fit of the deck to the hull, spot on.

Everything is here..water outlet, water line, GOOD hatch seal, new driver heads, etc.

The jet pictured is one of his modded jets, first, and most importantly, a FRONT bushing surface support, flex shaft thruout, to the rear bushing.

The grate he supplied, is SERIOUS stainless, all installed, aint gonna be bending that easy.. with the water inlet already installed in the bowl, also.

I will be adding as I build it, but, the most important thing I can say here is that Steve is CRAZY!!!

This is the best value out there $$ wise, he has the passion here, cant be about money, waay to much time in this in hands on things..

These are the type of men we need to support, to trade with, its BECAUSE of guys like this we have diverse hobbies, not just what kyosho, graupner, and hobby king bring us..they are about the money..this is about the FUN...

Once again, cant stress enough about supporting men like this..they come and go, because of non support, when they BUST THEIR to bring US fun toys, at a SUPER price. lets keep THIS guy around..let him feed his kids, or, he will have to get a REAL job..

And we all lose.

ps. the motor and esc are MY favorites, build to follow in the next days..

pps. as you see the roll bar is a dead fit for the nqd, that tiny one was my biggest dislike on more!!

Anyway, here is the result. First pic is the stock Steve hull which is identical in outline to a stock NQD one. Second pic shows the change. I've just given it a quick sand which shows the areas which will need a glaze but it's not as rough as it appears in the pic and will soon tidy up. The red line was just put onto the pic in Photoshop to show up the area which is now flat. Probably too much but there we are. Too late now. I had to do that much to take out the reflex curve in the keel and to widen the pad in accordance with something you said when discussing hull forms with Heinric H
There are many things in life on which I wouldn't take your advice (like wives, for example ) but this is one on which you know a lot more than me.
What do you think
I flattened about 3/4's of an inch in front of the jet intake. i just used my hot air soldering station to heat up in front of the drive and the table as a flat surface to sit the boat on and flatten the bottom. it feels like its more stable while its accelerating and it has less cavitation at full speed.

From what you found it seems Steve has improved his act over the last 3 months as far as both production and packaging. Yours seems faultess but my transom is a bit misshapen and although a battery tray was supposed to be included, it was absent. Didn't tackle him about it because I probably wouldn't have used it anyway. Although he provides a water outlet, it seems you are supposed to run the in-feed line through the transom without any support. I think that is a potential leak point so after I've sorted the transom I will be using a metal inlet as I've done on my NQD hulls.
Anyway, I'm glad you are able to make progess. Now all you need is the return of soft water

Wow I've been missing out. Busy with work and with no laptop my time online is limited.

You're guys' boats are looking great and it's cool seeing the little changes you all keep coming up with. I'm looking forward to seeing your new build Chi.

i've unfortunately not got out with mine lately. Made a platform for the GoPro out of perspex though, so the next video should have some POV. The GoPro has the led back on right now so I'll remove that to shave a bit of weight.

Mad, soft water is a ways away yet.. water inlet hose being silicone, seals itself, as long as the hose is a bit bigger than the entry hole, it is its own gasket, dont forget..

T, cam looks good..does it make it top heavy, tho?

Cam was alright, I can tell it adds some weight obviously, and in the water it does cause it to be a little more rocky, but surprisingly enough, it still ran quite well. It was a little choppy on the water today, so a calm day will yield better results.

With all the activity on this thread i felt i had to get back in the game with my boat.

Just made the deck but im not sure i will keep the angle all the way back, depends on how i will solve the hatch part.
On my small electric GHZ boats i use tape to make it totally watertight so maby thats the way this will have it but with a detailed part covering it.

Scub, because its plastic, and has to flex, I used a epoxy, once the jet was in, I reglazed it with filler, and spot painted it back in..

If you are workin on plastic, a GOOD, key word good, 2 part epoxy will do the best, its sandable, and paintable..just acetone the plastic first if you want a good bond..on my boat, the hole filling and the jet are held in by one single pour of there aint gonna be no issues..I am more used to workin with fiberglass hulls, lot more time and effort there, this is kinda nice..

Throw us a few pics, so we can see whatcha got, sounds like a decent project.

T ! gotta see the vids..
