So, This is my first build that life seems to suddenly have given me some time to play with. I have been fiddling with this for a long time and now i would love any suggestions, Build recommendations, thoughts or comments any of you are willing to share. thank you in advance!! looking forward to seeing yall on the water. Craig
Anyone want to show me how to wire fuses in for my motors and ESC? Do the fuses go between the motor and ESC? Or between Batteries and ESC? Or in a fashion i am completely missing??? I am running Johnson 550 motors With BC gearboxes. Any recommendations for Fuses and ESC are welcomed and links to them are rejoiced over! Thanks Craig
The (2) that are most commonly used are the Mtroniks. Mtroniks comes ready to go. It is made for boats, and is already potted in epoxy. $65.00 http://www.strikemodels.com/products/speed-controllers I am cheap so I am using the Hobby King ESC. It is made for cars, so you need to take the case off and pot in epoxy yourself. at $10.67 I pot up a spare and put it in the spares box. http://www.hobbyking.com/hobbyking/..._X_Car_45A_Brushed_Car_ESC_AR_Warehouse_.html
Fantastic, I ordered 3 http://www.hobbyking.com/hobbyking/..._X_Car_45A_Brushed_Car_ESC_AR_Warehouse_.html last nite, one for each motor and a spare. My plan is to put a 15 amp auto fuse between Esc and Motors, 1 on each motor/esc combo. Or do I run just 1 Esc for both motors?
Can u program out the brake? Fuse could=dead in the water. If you realllly have to have one go closer to the 45 amp rating. However for mtronics or hobbyking I do not trust their ratings . Ummmm it catches fire at 45amps so lets rate it there
If you run 1 esc per motor then fuse closer to the ESC rating. You can simplify your plan though by running both cans on 1 esc.
Honestly the HK ESC are so cheap I can't think of a good reason to not go with two. Redundancy is always better. I don't think it is necessary to fuse them, it had been my experience that using fuses just leads to more problems
I received a Traxxus Stinger motor in the mail today, Wahooooo, My plan is to use it on the pump with the hope that it will help me stay on the water longer with out sinking or maybe use up all my ammo first before sinking....
So, after reading the info at the PPB site, for Pimping out your Pump(Thank you Bob and Tyler for making this available). I ran out to the garage and got to work on my pump. I disassembled the pump and began by sealing the old air inlet and drilled a new one in the top, balanced the impeller, used a little silicon to seal it up while installing the new motor after i soldered a couple caps on it. While working on the pump I thought i mite have heard some skittering around somewhere in the garage. I was planning on setting a couple traps after i put the pump up to dry. Turns out, I dont think traps will help: I am in need of a sure fire way to rid my ship of gremlins!!!! All advice, recipes and Information is greatly appreciated and accepted. Thanks, Craig
Well, more parts, pieces and ideas are accumulating, while I am trying to get the Water channelling in the hull. Have not made progress due to everyone else having bad days getting in the way my good days or something to that effect. So on to the good news! ESCs have arrived, Power poles are here, Noodle wire is in hand, New servos for everything as well! . What ever it is? It seamed to approve of the new pieces and parts! I doubt he is of the same Caliber as Chief Boat Inspector Tuxcat!, but hopefully some day in the near future he can get lessons from Tuxcat in person. I am planning on scotch coating the ESCs. Waterproofing the servos, Per Tugs tutorial https://rcwarshipcombat.com/threads/sb-101-building-mn-edgar-quinet.441667/page-16, Any reason to do it differently? Remove heat sink first? any suggestions? thanks craig.
Yes, but not as counterproductive as covering the contact surfaces that the heatsink is meant to cool - so be careful with the skotchkote
I've been dribbling West Systems epoxy in the gaps between the ESC proper and the heatsink. It takes a few times to get it thoroughly potted in there, but I'm on the '10 minutes to victory' plan, so 3 applications is easy to do without affecting the weekend build sessions...
