***INTRODUCING*** The AquaCraft UL-1 Superior Fe Hydro RTR 2.4

Bill, we all know in the hands of a genius, what they can do with a prop massage. Newbies, including myself you are not going to obtain this performance level with a prop change!!. No matter what props you try.

So, again, who do we hassle for another video??? (hopefully one where we can see it corner)

OK, but I am not following you. I was only commenting on the fact that Brian got the boat to go even faster than the speed shown in the video that was posted. It all goes to show what the potential is. I've seen people posting already about how they are going to put Neu motors in on 6S and so on.

It is a nifty little boat and I can see a whole spec class growing out of this.

I hear the batt trays can only handle a 6 in battery. Is this true. Can Brian or someone with hands on this boat please take an exact measurement? I just bought 2 neu 4900's that are 6.2 in long. Will they fit?
Thanks,
Alvin

Bill, I was just stating that the average RTR boater will not achieve what the Snowman produced with a prop change. Plus they will be very happy with 40-45 mph if they can handle the right hand turn.

The tub is a huge open area. You can fit all kinds of stuff in it.

air dam

Hi racers,

I'm a nub when it comes to hydros. Can someone post a pic of the air dam Brian installed on the UL1 to keep it from flying?

Tks in advance

[raptor347]

I was just going through everything and cleaning up the disaster that is my shop.

Here you go:
Air dam: 1/2" deep hatch tape (flexible), 1 3/4" from the front of the tunnel.
Strut: 1 1/16" deep with .020" at the front (a little negative).
Prop: Very thin full bladed 2047 cupped at the tips.

Prop measurements off a speedmaster pitch gauge. Taken at 1/8", 1/4", 3/8", 1/2" from tip:
Spacer .062 .125 .187 .250
---------------------------------------
.125 3.5 6.75 11.25 17.0
.250 3.5 6.75 11.25 17.5
.375 4.5 9.0 14.25 20.5
.500 5.25 10.25 15.5 21.75

What the numbers mean for those who don't have lots of prop tools:
The average pitch on this prop starts at 3.7". The outer 3/8" of the blades have been cupped to increase pitch and to concentrate the thrust cone. The pitch out at the tips is roughly 6.4". You can see in the picture where the blade has been worked. Now if you don't want to do lots of prop work, an M645 will get you into the low 50's with the same airdam and strut setting.

One way or the other, it's a nice boat. And the 4900's will fit, no problem.

Is that the new spec Rigger hull in the background?

Thanks about the batts Brian.

Yes it is. Sponson molds this week.
