Captain's Log: Well I found a 6 volt 8.5 amp Battery. For my Brooklyn to use! Just have to order her main motor and a new smoker! Both of which will be at 6 volts! Now, If I've done my math right! And all I use is her main motor. I would end up with about 2.5 hours of run time! But, If I use her main motor and smoke. I will end up with a little over 1.5 hours of run time! I was lucky in that I have a buyer. For her old 12 volt motor and 12 volt smoker! They have about an hour of use! Not exactly what I call used. But, Have to sell as used equipment!
The heating elements in the hairdryer had two different wire gauges as elements. I removed the lighter gauge thinking they would probably draw less current. I am attempting to use 6 volts as that is what my boat is. 1. First Photo: Took a length of element and stretched it out as shown, started with a longer piece about 8". If you are at 12v probably longer. Use some alligator clip jumpers and attached to one end, ran it to negative terminal of my 6v SLA. Took another jumper and attached to a point on the wire, say about 7". JUST TOUCH the other end to the battery positive to see if it glowed, it did not. So just moved about 3/8" at a time till it glowed - See Photo. CAUTION, make certain you have a nonflammable surface to work on, I used a tile scrap. IT GETS HOT FAST AND WILL BURN, DON'T ASK ME HOW I KNOW. That's why I just touch the terminal till it glows then stop, let it cool for a while. 2. Cut element to length, than take your 16 gauge wire and the crimp tube shown in earlier post. Insert both into the tube and crimp it. I used a side cutter and carefully just squeezed enough. Make sure that the element will not pull out. Do the other end. Because I am using only 6 volts, I had flattened out the wire to give me more wraps on the wick. See photo and note. 3. In the lid of the box, I located the fan at one end, the exhaust stack at the other. Drilled a hole matching the fan opening and secured with two screws, drill small pilot holes so as not to crack the plastic. Drill hole to match brass tube OD, tube is about 1" long or so. Super glued brass tube in place. Excuse the sloppy copper sheet work on the inside of the lid, it was an experiment at the time. I added this a a bit of a heat sheild as the wick and element would sit below this. 4. Next photos show the interior of the box, not the best photos of the process as this was already built.... The mint tin set inside the plastic box was an idea to do two things; first isolate the heating element from the plastic,and two, provide a smaller vessel for the fluid. You may want to just use a metal container instead of the plastic box, again I was just using what I had on hand. The wick is laying in the tin with the element propped up at on end to keep it out of the fluid. Photo shown does not show much fluid in place. This needs some work, but worked for this test. Experiment, just be sure that the lower portion of the wick is in the fluid and the element wire wrap is above the fluid level. For the test, I used some mineral oil and a bit of glycerin, smoked very well. It's late so I will run it and photograph tomorrow. Cheers, Joe (Excuse the Imperial rather than metric)
Hi Doug, No, I mean $40.00 for all three Batteries! But, I'm still looking! I found one for $23.33. It's 6 volts at 8.5Ah and it weighs 3.1 Lbs. Which is just the right Ballast for Tug Brooklyn! Also ample power 1.5 hour run.....👍
Captain's Log: After careful consideration. I have decided to use only one battery at a time! This being 6.5 lbs. is way too much weight. Her bow is too low to the waterline. She get's thrown off by the weight. So, one battery at a time will be used! Now, having lowered the volts. From 12 volts to 6 volts is a problem. See her main motor and smoker. Are 12 volts each! So, now I have to replace. The main motor and the smoker. To a 6 volt system! This is not so easy. If any of you are familiar. With Dumas and Harbor model products. You know this ain't cheap!😭 Luckily, I will be selling both parts. Together next month! As both parts are in new condition! I will then order a 6 volt main motor and Smoker! Oh, each battery will give me about 1.5 hours of run time! And that's not bad at all..... NOTE: I'm only losing $10.00 on the resale of her Motor and Smoker!
Captain's Log: Well, I order new batteries for the Tug Brooklyn. I placed the order about a week ago. I received them last night! Before I continue let me say this. I was using the Batteries from Tug Serenity AKA Jersey City! Those Batteries are 6 Volts at 2.5 Amps! For a total of two! I saw what I thought were the same battery. Only at 6 Volts at 8 Amps. For a total of 12 Volts at 8 Amps! Well the batteries are huge! I had to take all of the Forward ballast out of Tug Brooklyn! Even then she's a bit bow heavy. But, I really want the extra Power! Because Tug Brooklyn is a 12 Volt Tugboat! Take a look at the Batteries side by side. It's a good thing there's enough room in her forecastle! I'm putting the Batteries end to end and they fit! Oh, the Batteries weigh 6.5 LBS!😱
Put together a pilot house based on some tugs I've seen. Just freelanced it as I went. I build a lot with styrene so I am used to just cutting and building. I use liquid styrene cement that fuses the materials together. See photo, will trim it out as I mount it, need to add some detail at roof and some Navigational lighting. Put on on 3mm plywood deck, same as hull bottom. The deck is also curved (proper term is SHEAR) and I started to build up some wood edge at the opening. Will sand everything well, then start sealing and priming all surfaces. Made a bracket for the rudder servo mount and an adjacent platform for the ESC and RX. Ordered two 6v 5ah SLA batteries. I will wire in parallel to stay with 6v and get 10ah. I like to stay with 6 volts as I want the motor to run slow like a tug should. Will wire in an in-line fuse. Haven't decided where I will put switch, up high somewhere to avoid water. I will show the wiring once I get to it. This build is going fast because it's a simple design, just what I was looking for. I work on it late afternoons and into the evening while I watch basketball games. About 4 hrs a day. Looking forward to building the hatch and getting some primer started tomorrow. Regards, Joe 👍
Steve, have you calibrated the throttle first? (read 2 and 2.2) on the instructions, You have to give the ESC a full, low and mid-point throttle position before you can start the programming. Plug in motor and ESC BEC lead into throttle position in REC. Turn on TX and give it full throttle. (make sure motor is held firmly as it may kick hard if started) Program - plug in batt wait 2 secs for beeps then wait 5 secs for musical tone (now in program mode) wait for 1,2,3 or 4 beeps (asks which program you want and will keep cycling through till you chose one) as soon as you hear the no of beeps for the program you want quickly pull the stick to the bottom and wait for the reply,- it will now cycle through the programs in step 3. Choose the one you want in the same manner as the last selection but by moving the stick to full throttle (if you miss it it will cycle round again) Hold it there and it will reply (musical beeps) wait and the program will return to step 2 and you can select the next setting to enter and repeat the process. Safest to set Auto battery and then the others as per chart especially min batt volts. Once happiness filled, follow the Program Exit instructions (step 4) Also as 'RN' previously mentioned, if you have a Futaba, you may have to reverse the throttle to make it all work. When finished, unplug batt, turn off TX, re start everything (TX, Batt/RX) and check. AS A PRECAUTION,MAKE THROTTLE NEUTRAL BEFORE RE STARTING IF YOU HAVE SET FWD AND REV, OR LOW IF NOT. BE AWARE THROTTLE MAY BE REVERSED ALSO). You may have to have a few goes but you will get there and realize it's not that difficult after all . If in doubt just un-plug the battery and start steps again. Just think of it like the ESC is asking you "do you want this"? at a particular set of beeps, and you are replying by moving the stick, or ignoring that question and moving to the next one. If you are using a pistol grip TX just let the trigger go and it will give you neutral/center (as per instructions 2.2
Schnellboot Radio control setup 3 Mtroniks M400 marine Motors (running at 12V, at maximum efficiency it will run at around 20,000 Rpm and pull around 4 amps. Start-up current depending on prop size (30mm on 4mm prop shaft) would be around 10amps (6-12 volts) 3 Mtroniks Viper marine 15 ESCs connected using Mtroniks W-tail mixer with 10-amp fuses used between ESC and battery’s Batteries are 1 Carson 2100 MAH High performance NiMH battery pack 2 Vanquish 22oo MAH NiMH battery pack All Batteries are 7.2 V I have tested the set -up all the ESC are synchronised, and all seems well on the bench but when I try it in test tank all the fuses blow, and I check all connections and there are not short circuits on the connections or switches can anyone help
Well Doug I have got one of these vapour cigarettes, free of charge, but need to get a power supply for it, it runs on 6 volts, will add some pictures when it arrives tomorrow, apparently it has adjustable air flow and has a 25ml reservoir for the oil. Cheers Colin.
Hi Sandgrounder There are a number of speed 400's with voltage range from 4.8 to 7.2 volts. The revs range is between 16,400 to 22,000 rpm. So 28mm brushless like a Prop Drive V2 2836- 1800kv(shaft 3.175mm) on a 3S Lipo battery with give you 19,980 rpm. ESC 45Amp. Prop 30-32mm 2 blade. If it's tight of battery space Hobbyking have small ones you can parallel together like the Turnigy 3S 1500mah 25C (73 x 33 x 27 mm). Regards Canabus
BTW Martin, going back to your original post- "Plugged tested (6.2 volts) Nimhs into Rx and it starts flashing ..." Did you check that the RX is Bound to the TX? E.g. by trying it with just a simple servo before messing with the ESC? Doug
Hi Gordon I restored a tarpon about 2 years ago, I received it in a very bad state, holes cracks all over the boat, I put a 457RE385 motor 6-15 volts MFA combo drills, tried it with a 12 volt much to fast I run it with 7.5 volt still fast, a 6 volt would be ok, the tarpon is not the best boat on the turn it does roll a bit, the photos on the water is with a 7.5 volt powering the motor, hope this helps. Cheers Dennis
