Aeromarine Conquest FE Open Cat 10S Build

[Rumdog]

Where did you get the idea for 4 drives? Have you tried this type of setup before? I've never heard of 4 drives on a cat. 2 per sponson, or 1 per sponson and 2 struts in the tunnel? Sorry, just curiosity, I think I saw you mention it in another thread.

I thought of the idea after i biult my36'' sprint cat and kept burning esc and motor up trying to attain speeds in the 70mph range. I wasnt the only thing i liked about that boat was how it handled and how stable it was at 75mph, I was using CC240hv and 15271y on 8s 2p n prather 240. All though the boat had enouph power to flip over under hard excelleration I wasnt satisfied with its performance from 0-60. I want the front end of the boat to jump when i punch the throttle like my mean machine did. Also 4 180 amp speed controlls=720 amps continuous and 1440 amp quick bursts. I wont need to run expensive esc or lipos and it has a good cool factor.

Wierd. I have the same sprintcat, which is actually 34" (sprintcat 40) I run 5s2p, 1527 1.5d and x455. If i punch it from a dead stop, the boat will flip directly onto it's lid. Every time. I have to feather the throttle onto plane then punch it. Top speed with that motor batt/ prop combo is 63.6 mph so far, but acceleration is the very least of a problem. 4 drives is going to be overkill IMO. Sorry about getting so off topic. rearwheelin, will you have a build thread?

I will start a build thread when I get my stuff in , it is probably going to be a slow build. Boat was a 34'' ...lol...Aeromarine says its 36'', probably cause the turbine hatch, mine did the same thing to, landed upside down everytime, seemed to run wet untill it got up to around 50mph or so, I ran four 4800ma 4s seriesed then parralled, I fried a 1527 1.5d and then went with 15271y a higher kv because of the thicker windings hoping the motor wouldnt build soo much heat. What I like about the twin props is that when the front end of the boat lifts it does it without the torque effect as long as you run left n right props. There is no doubt the boat will be over built but i think it will be a blast to run and the sound of it sould be increadable on 6s ! My hangup is how too make the boat carve turnes like the single props do. I am pretty sure that i will run the struts toward the sponsons, left and right on each side of the boat, but i kind of need the boat to be sure, i dont want my rudder directly behind a prop catching prop wash cause I believe that will cause unneeded drag on the rudder and would make the boat run wet at slower speeds also dont want air in my water lines. I will keep fellas informed on my build .

Just put all the last pieces on and she is ready to hit the water.

Installed the carbon water jacket from Andrew. Drilled and tapped two inlets on the bottom and two outlets on the top. The cooling water is "Y"ed before it comes into the Schulze. From the Schulze the cooling lines connect to the motor and then out the left side of the hull.



I'll use a FP RX 2S lipo for the reciever. Because the HiTec is good for direct 2S power and so is the reciever I'll skip the regulator.



Another view of everything fully rigged.



I am using two pairs of O-ring hold-downs on either end of the boat. I replaced the smaller diameter O-rings with some larger Silicon ones to spread the distance apart to allow ample room for tape down width.



Just need some water now.

Bro!
did you ever run this bad boy?

Let's see a vid

Yes, I finally got to run her, but no one else was around to tape her running. She ran in the low 70's with a mid level set-up. Would be good for a 7 lap race, but no more.

Next time I'll try and get some video.

Tested at 71.2 mph Saturday

Guys,

I finally got the chance to run the Conquest with the repaired and beefed up Schulze and WOW she runs great. Two runs on 10S with a X457 and 71.2 mph both runs. She airs out beautifully on the straights and turns consistently around the ends. I am very very happy with this set-up thus far. No video or pics as I was the only one at the pond.

I downloaded the data last night and controller temps were around 83C, Batteries around 60C and motor around 75C are end of run.

She goes exactly 8 laps before the LVC cuts in on 6500mAh 1P packs. Just enough for 6 lap race. I will be looking forward to July when I can race her in the open class at our next district race.

Sounds dialed ...... I am very curious on your ready to run wieght.

[RaceMechaniX]

I have not checked yet as I do not have a scale at home. My guess is around 13 lbs with 10S1P worth of batts. Feels light.

Mr. MechaniX can I ask you a question about your esc?

Mr. MechaniX can I ask you a question about your esc?

Of course, ask away.

you can choke on your popcorn. You eat that alot I guess thats why your build threads have two pages of talk not one bit of construction. Let the big boys play while you learn to build.LOL. Less type more wrench thats what you need to do.

[Xfactor]

Anyway Mr mechanix I know some of the shulze escs have a closed loop option. Does yours? If so does the manual give you an idea of what the motor needs in terms of sensors for implementing the closed loop function on the esc? Thank you MR. Mechanix.Ill just pm you any further questions cause you got people on here who dont even know the basics, I mean they need help on motor choice but they think theyre ready to chime in on discussion about closed loop esc function. They will just get in the way of a technical discussion.Thanks X

Looks fantastic! You are a true craftsman!
