UL-1 Build. 55mph+

[nate]

This Is Just a little preview of my New UL-1 with the Neu 1515 1.5y, hydra120, and a few other goodies.
Before the question's start, Yes I have ran It one time....and Yes its probably the fastest boat Iv ever had my hands on

I was really hoping that my GPS would come in the mail today but as usuall eBay sellers take there time.

If it comes in Ill get a video with the speeds as the boat goes out.

I didn't really have the time today to do alot of adjusting work with the strut and I didn't want to risk going too fast and the Turn fin bracket come flying off lol.

All I can say is WOW. Its fast, Im not sure how fast... but in the 50's..

Ill try for a video in the morning.

Cool Nate! What prop are you using?

...

[Ub Hauled]

I was gonna say, that looks like a 935 and if it is this setup is not going to last very long (if you are running a long time).

[nate]

Thats a 937. And I made one pass with that prop, wasnt too great.

I then swapped over to an m445, then made two hard passes wide open around 5-6 seconds, brought it back in and checked everything... temps were good, never passed 128 degrees, of course I didnt run it that long.

There was a reason for that as I mentioned, I didnt want to crack the hull were the Turn Fin bracket was..Cuz this beast flys! Very quiet and smooth as well.. I absolutly love my Neu motor. Good running system in the boat. Programing is a breeze, and speeds are great.

Anyways, I did happen to get the Hull beefed up behind the TF bracket. I used 1/8" CF and used fine fiberglass with 5-10min Apoxy and resin.

Iv also used a diffrent TF. I dont see the need for that Grim fin thats got so much tuck.. and so big...lol Ill make one of my own in a few days.

Ill post more pic's in a bit. I know the ones I posted the night I had the boat wasnt all that great.

Here's the pictures of the Turn fin, setup, ect.

Did you make that turn fin from scratch or cut down the AQ one?

No, This one came from my A-Z Racing hydro, I didnt have a smaller one but this one, so I swapped it over. Im not to much for running turn fins with tuck in them on the UL-1.

My last UL-1 had a TF that had no Tuck at all and worked just as good..

[sailr]

I agree. Not sure the tuck is good. If the fin isn't dead straight, the tuck becomes a diving or lifting plane. Does A-Z have a website? I'm not familiar with them.

Turn fins seem to be rediculously priced for such a simple item. Somebody, somewhere could make some reasonable profits making a wide variety of types and sizes of TF's at a reasonable price.

[sailr]

Oh, yeah, I have seen the A-Z stuff. Looks like a nice turn fin. That's all I'll say. Haha.

If somebody that's a guru on turn fins would come up with a bunch of designs, sizes, etc. for various types of boats like Hydros, Riggers, etc., I could see about manufacturing them at one of the factories I use in China. They are always asking me what we need in the way of products.

I recently searched for some turn fins. Not much to choose from and they are outrageously priced in most cases. I did manage to get a pretty nice one from Horizon for a reasonable price but everyone else out there is a bit nutty over their fins for such a simple product!

Anyone? Some cad drawings would be great.

Correct. I have made a few, If I had a CNC machine and a 2 year at machine shop at my Collage Id spend the $6,000 to buy Manual CNC.

My bud had one that him and a friend went in together and purchased...

It never gets used, some of the manual machines are hard to work with, and just to build Turnfins... thats hard to make your 6 grand back just selling TF's...lol

anyways.


I ran my UL-1 again about 30minutes ago.. OMG I absolutly love this boat.
Correct me if Im wrong but I ran my UL-1 about 6-7minutes on 7500mah's...

Did about 10-15 oval laps almost wide open 88% of the time except turns...

and the Hydra never got above 145 degrees...

the motor was checked one time, has no water jacket...and set at 159 degrees along with a few other things checked...

The CC wires were at 124 d/F

Lipo's sat around 100-114 d/F

and the rx/tx 2s was at 99d/F...

So I have seen some hydras get up to 166 degrees...

Due to my setup the boat would be unbelievable with 6s...but then would start seeing many issues in heat. Probably need a Hydra 240.

A-Z TF is actually kinnda cheap haha

[sailr]

All I saw on their website was the Aquacraft turn fin. I'll look again.

A-Z TF is actually kinnda cheap haha

I love my stock UL-1 too after doing all Darin's mods to the turn fin, etc. The boat runs and handles great. Too bad the hull quality couldn't be a bit better. I suspect AQ will continue to improve the boat in future releases. It sure is a winner as far as price vs. performance is concerned.

I work with one company that has 30 CNC machines, CNC lathes and screw machines, etc. They are always looking for projects! You are right though, gotta be quite a bit of quantity involved.
