KNPC's 43'' Conquest build

[monojeff]

Decals look great!!
Nice work.
Look forward to seeing it run.

Nice work Kevin and Monojeff! I can't wait to see this cat run... Are you going to go with flex cable in brass tube (w/o liner)?

Thanks
Yes, I'm going to run a 1/4'' flex cable in a 5/16 stuffing tube with no liner. I haven't run a liner in my last 5 or 6 boats and its been working well for me.

After a bit of a wait my 2230/1Y arrived today and I can get back to this build . I will post progress as I go along.

Here are a few pictures of the motor, for a size comparison it's next to a 9xl and a coke can. This thing is HUGE.

A couple things as I get back into this. First, as you can see in the picture, the motor is 1'' longer than the dimentions I gave Peter for the mount so hopefully I gan convince him to make me four longer connecting rods. Second, I would like to mount the motor and ESC as it is in the picture. The problem is the length of the wires, what is the best fix for this? If I extend the ESC wires to the motor, what is the proper way to do it with the least resistance? My other option would be to put the ESC in front of the motor, this would be a PITA to get at and the wires from the ESC to the packs would be longer. I would think have the esc to motor wires longer would be better than having the esc to pack wires longer.

Any suggestions would be great

I say go with 4 stiletto outboards with ul1 motors hahaha. Hey but Saturday morning maybe?

Why fight it? The best place for the ESC is on top of the motor, this is where most racers put it. That means short motor wires and short battery wires. With the motor over the coupler it is in the worst place to get wet, and in the way for tightening the cable. This one is mounted too high.....




This is another option:

Jay, ideally I would like to put it one of those two locations you pictured. I can't put the esc on top of the motor because I don't have the hieght clearance under the hatch and if I put it on the side of the rails, which I may do, I would still have to extend the esc to motor wires. The wires coming out of the motor are very short as you can see in the picture. As for the short esc wires that is my doing, this esc was in another boat and in an effort to keep all wired as short as possible I cut them to only what I needed for that application and screwed myself in the long run. The only place it could go without extending the wires is in front of the motor, this would be a pita to access and impossible to get temp readings because it would be under the deck.

With that being said, there is no way I have thought of around extending the wires it's just a matter of the best way to do it. Should I use connectors or just solder the wires direct? What gauge wire for the extentions?

It may be tough to solder the two wires together with adequate contact. It may be easier to solder on large connectors (8mm) and either just plug them in, or solder the connectors together. Eight gauge wire.

Thanks Jay, that's what I needed to know

I've got a few more things done on this. The rails are epoxied in place, the stuffing tube is bent and installed, hardware is sealed and mounted.

Peter has made and sent out some longer connecting rods for the motor mount.

I guess next up is to locate and mount the servo, floatation, and soldering.

What steering servo in needed in a hull this size? I have two sitting on the workbench to choose from. First one is a HS-645 - speed .20sec / torque 133oz, the second is a HS7954 - digital / speed .15sec / torque 333oz. Obviously with a servo - stronger, faster, and digital is better, but is the HS7954 necessary or would the HS645 work fine. I don't want to strip a servo taking a corner at 60mph, it's alot of boat to turn.

Good call on the digital servo. Since you have both, the stronger one is the best choice. While many gas guys run 645s in their cats, FE cats are a lot heavier and the extra torque is an advantage. Too, digital servos have a much stronger centering force, helping to keep the boat running straight.

Be careful with the Tactic receiver sitting on carbon. Some have reported limited range with the receiver near CF.

I made up some battery trays and got a few other little things done. Once a couple parts arrive I should be able to wrap up this build in a week or two.
