AquaCraft 60 amp ESC questions

[mgmgmg75]

Hi all. Just getting back into a rebuild of a 95' Cape class Coast Guard cutter, about 36" in length. I have a new AquaCraft 60 amp ESC and an AquaCraft 36-56-2030 kv brushless motor.
Does anyone have installation/programming instructions for the ESC?
Also, can a 12v sealed lead/acid battery be used with this ESC?

look up Aqualcraft UL1 or Revolt 30 and read their manuel.
It may help you with this. I am pretty sure you will need two 2S (7 volt) or one 4S (14 volt) Lipos

The aquacraft need a total of 4s or 12 nimh/nicad to operate. That is over 12volts. It might go into low voltage with the lead acid battery if it will start the motor.

That ESC don't need programming connect the motor wires, plug in the battery and pull reverse then release and it is ready.

Make sure the throttle trim is set to neutral.

Works just fine on the bench. Lead acid batteries should hold their voltage with less drop under load than the much smaller lipos. I'd give it a try.

Thanks for the help all. Yes Speed3, I am concerned about the stutter bump voltage, but a fully charged 12 vdc should be around 12.6.. With 2 of them I am hoping to get a decent run time. With all the lead acid batteries I have, it seems a shame to switch to NiMH OR LiPo. I am guessing to change to a different battery type with chargers and all, would be over $300.

I am no expert on pleasure type boats, but an AQ 2030 in a 36" (heavy) boat with a fully submerged prop doesn't seem like a good idea. I would expect a slightly larger motor with a much lower KV would be a safer option.

The other comment I have is about the AQ 60amp controller and the voltage cut off. I seem to remember this controller doesn't have a "hard" value for the voltage cut off. If I remember correctly, the controller somehow calculates a cut off voltage based on the initial input voltage. I am guessing that is a function of needing to arm every time you power up (plug in a battery). Unfortunately, I don't know how or who you could talk to confirm.

good luck

I like reverse on my scales...... don’t forget this esc doesn’t have that.

The set up sequence is easy plug in battery, hold wide open throttle, hear beeps, release throttle, hear more beeps. Done. See page 4

LVC is not fancy, it’s based on 4s and as previously posted it’s about 12v. Maybe a little more I forget....see page 3 of manual

Link to a revolt manual which describes it further http://manuals.hobbico.com/aqu/aqub24-25-manual.pdf

What ESC do you use on your scales?

[trigger]

Mine are old brushed setups using a regular car esc with a cooling fan. Nothing special at all.

I don’t think you will be happy with the low speed control of a brushless motor in a scale. I used the 600 size brushed motor from the Aquacraft fireboat to repower an Atlantic tug on 3s. Tons of power, it will stand up and wheelie lol.

I agree with the guys.
If it were me I'd go with one of these https://www.offshoreelectrics.com/pr...clr-hh-prb2314 and a 6 or 700 size brushed motor. If you are interested and can't find a suitable motor let me know. I still have quite a few new BOSCH (700 size) drill motors that I used in my scale boats. That was all I did before I got the speed bug & I'll get back there one of these days. The BOSCH motors run well with the above control 12v gel cell and 45mm 3 blade scale props.

That’s what I remember about the SV27 , pull full throttle after plugging in batteries lol

[Speed3]

I think using the brushless in the scale will present one problem. Over heating due to poor cooling as a result of slow speeds.

Thanks guys. I guess I'll save the brush-less for a speed boat and purchase a different set. The thing is this pair was recommended by a hobby shop in Milwaukee! Attached is a quick pic of the boat in the restoration process. Coast Guard 1.jpg

The aquacraft will have more power and torque than the 600 and 700 brush motors. So from that point of view the hobby shop give a good recommendation.

The aquacraft uses neodymium magnets which can get demagnetize at far lower temperatures than ferrous magnet would. So the long runtimes combined with little to no cooling can damage the magnets of the aquacraft motor. The speed control will get hot too.

The 700 brush motor have ferrite magnets and an internal fan. So the construction of the 700 would make it more suitable in my opinion.
