Looking for someone to finish set up of my MHZ Mystic 114

Thanks for the info fweasel. I didn't know I could use standard threaded collets regardless of the direction the motor spins.
It was supposedly shipped with a couple other items last week, so I'll just let it fly. Always something new to learn, especially for a first time build, and I greatly appreciate everyone's help/feedback.

In theory, it makes sense to use a reverse thread collet on one side of a twin build, but in actual practice, it's no needed and I find it a bit confusing while prepping the boat.

Its been awhile since I made any updates on my progress with the boat, so here is where I'm at. I have most of the electronics trial fitted in the boat. I have the ZTW Seal 200 amp ESC's trial mounted with all the necessary connectors installed by OSE. Still have to set up/calibrate the ESC's, but that will happen eventually. Not sure what timing I should apply for these motors. MHZ lists 5 to a maximum of 7.5 degrees timing. Maybe someone could point me in right direction? Also installed the steering servo and picked up a Traxxas waterproof box for my receiver. Still got to get the Y-harness to combine the ESC's, and will cut the red wire on one, so only one BEC is connected to the R/X. I plan on doing all my wiring and hoses in black cable sleeve to protect everything and to give a sharp/professional appearance.
Only other part I'm trying to figure out now is how to wire/power the water pumps. Since I will be powering the receiver and steering servo with the ESC's built in BEC circuitry, I was planning on using the installed thru deck main power switch to turn the pumps on and off, and probably use a separate battery pack for the pumps power supply. Was going to y-harness the two pumps together and plug into the switch. Anyone have any other suggestions regarding wiring these, and if one 2S 6 volt pack would be sufficient to handle both pumps? I asked Steaven about plugging them directly into the receiver and run them off the BEC, but he didn't recommend doing that, as they'll probably pull too many amps on the ESC.
But overall, looks to be coming together...

I don't know anything about those pumps specifically, but I would not run them off receiver/BEC power. Definately power them off their own small LiFe or Lipo battery.

Do NOT cut the red wire on one of your ESC's. Your reason for doing so is correct, but you'll thank me later when you need to power up your receiver with just the one ESC (during calibration) and need that wire connected. Use a small micro jewelers screwdriver to de-pin the red wire from the black plug, then heat shrink it out of the way to the rest of the wire bundle. Then, when you need it, you can slip it back into the plug temporarily.

Thanks for the heads up Fweasel regarding cutting the wire. What I'm planning on doing is to first calibrate each ESC individually. And then after calibration, connect the two ESCs to the y-harness, and de-pin the red wire only on the y-harness to one of the ESCs. That way I'm not pulling out anything on the actual connector attached on the ESC.

I'll definately use a separate battery to power the pumps. Will have to change out the odd plugs that came on the pumps and install the JR connectors so I can plug them via y-harness into the power switch.

Its been awhile since I put an update on here regarding the progress on my model, so here is one at last. Got quite a bit done, and I am pretty impressed with how this project is turning out so far. Have the ESC's both mounted in place with heavy velcro and tied down securely with wire ties. The wiring connections to the motors are shored up, and I added some extra heat shrink tubing to the wires on the motors to protect them from chafe. The cooling system is now all wired and plumbed. The pumps will be ran with a 6.6 volt 3000mah LiFe receiver battery, and are wired into the thru deck power switch for turning the pumps on and off. I finished my water cooling lines in all black braided sleeve, which surely changes the overall appearance of the interior. Mainly all I need to do now is plug the channels into the receiver and secure it in place, calibrate the ESCs, and make a hole in the rear deck for an antenna mount. I'll also be installing finger-twist cowl locks to secure the hatch and add foam gasketing to give a good seal for the hatch. And then I need to see about props.

Sent my boat out last Tuesday to have the JBS Racing livery graphics package professionally installed, and I should have it back by Monday. Casey from Visual Graphics is doing an awesome job, and he has been keeping me updated with plenty of pics!
