Aquacraft Atlantic Tug

[DK535]

Just got my new Atlantic Tug which I'm converting to a retrieval boat. Anyone recommend a brushless setup for this boat? Was thinking of putting a pro boat miss geico stock setup in it 1500kv.Just looking for a little more speed then the 550 brushed setup?? Also would an outrunner setup be better?

Brushless is not needed for a tug. If you want a bit more speed, increase your voltage. The stock input voltage is 7.2v correct? Go to 8.4v, The Rio EP uses that esc and is rated to use 8.4v. I am unsure if that ESC will go to 12v but THIS one will. If you make the jump to 12v, you should change the prop because the stock prop has a lot of pitch for scale. more Pitch = speed. less pitch = torque.

Thx Diego for the advice. Any prop recommendations?

[Diegoboy]

It scares me because the Aquacraft website says it's a 3mm prop shaft. If it is, your prop choices will be very limited. I hope they are jyst rounding a 3.17 in shaft (1/8") Can you measure the shaft for me?
Plus the prop is 29.8mm diameter. If you look where the shaft comes out, there's not much room to go larger in diameter without hitting the keel that supports the rudder. a 30mm prop is plenty, but let me know the shaft diameter and I'll link you to a prop for 12v

[DK535]

It is 3mm .12.

[Diegoboy]

The best 12v 3mm prop is a RABOESCH 25mm diameter (vs. your existing 29mm), 3mm shaft, 4 blade, R rotation (same as yours).
It can be founs on THIS page, just scroll down to 147-03

Price= $13
Diameter= 25mm
Rotation= R
Shaft= M3
Pitch= 25.6

Thx bud I appreciate the info! Ordering today. I'll let you know how it works out

I have a brushless setup on my AQ tug. The best improvement is the run time is much longer. I setup a water cooling pickup with a brass tube mounted on the rudder just behind the prop. It's surprising how much water flows thru the system much more than my fast boats. At full throttle it shoots out about 5-6 inches from the side of the boat

Wow thats sick. What kind of motor and what speed did you get? Any vids?

I think I would like to go to 8.4v but whats better nicd or nimh????

Hi,
You want to go with the nimh cells.
Shop around and check prices because they are not to cheap,
When you compare them to lipo's these days.

Also I may have some laying around from when my Rio ep was brushed and then modded to brushless now,
And some stock esc to.

Thanks for the help. . I have a 2000mah that I run in my drift car. so I can use that until I find one I want.
I would like to put the tug in the water and just let it sit there until its needed. probably looking at on average 4 to 6 hours with lets say 5 or 6 recsue missions. (my buddies roll a lot lol) would I need a much bigger mah battery to achive that kinda set time?

[lenny]

2000mah is not very much run time for a boat,
Boats pull a lot more amps all the time then most other rc stuff out there.
It is because of the constant drag of the water on the hull,
I was using 7.2v 3600mah and 7.2 5000mah packs for my Rio ep,
And also would use 8.4 5000mah packs when running for a good speed burst at times.

[solodare]

Got a 3000mah, cause of the price point.
I would like to launch the boat and kinda let it sit out there until its needed. Is that bad for the electical system to just sit?

Bump from the past.. I'd like to know the same. Setting up my Atlantic Tug Ver.1 as a rescue tug, just installed a Hobby Wing 1060 Brushed 60amp ESC. Much better than stock. Now what to do about letting it sit waiting for my FE boat to flip? I think i will mount a switch to the cabin so i don't have to take off the whole cabin to access the ESC switch. any suggestions would be very helpful.
