Hi I am using a Blue Rain esc rated at 60 amp 480 amp stall current .Has all the features of the viper plus a finned heat sink and cooling fan . Powers 2 black and decker 600 drill motors with Graupner series 162 props motors approx £3.50 and esc £6.43 All on E BAY Or motors can be had from Potts in Derby .The motors draw 30 amps at full speed and I use a 5000 3 cell lipo The expensive bit Hobbyking supplied .The boat is a Jules Verne Cheers Ian T
Hi Ron. I am currently building the Aeronauts Pilot Boat Kit. It is reasonably well advanced now but I still have to fit the electronics. I bought two 400 sport brushed motors and was advised at a very early stage that two speed controllers were necessary. I looked into various solutions and found that Hobbyking sell a dual speed controller especially for two motors. It is a Hobbywing Quicrun 860. I hope this helps.😊 Peter.
Steve. Since my last message, I have made progress, purchased a kit from Cornwall Models. Started building hull just before Xmas and as you mentioned, you need to have patience to get it right. Before going to far, I am planning how to set up the Motors and the Speed controller. I have got a Viper Marine 25 ESC and 2 Motors (380's). Looking back at some photos of yours, it looks as you have 2 Speed Controllers. I am having problems in getting the ESC to talk to the 2 Motors. Do I need to have a second ESC to operate the 2 Motors? How would this be set up through my Hobbyking Controller? Would appreciate some clarity of my thinking. Best Wishes. Ron👍😁
After building the mine laying rails I then purchased scale German mines , only to find out that they are 4mm wider than the rails on the boat, ...what to do , cut the mines (8) down and rework the base and wheels to fit the boats rails or move the rails wider ..... moving the rails ... slow going , found that the motors I have are more aircraft/drone use per the esc, , no reverse .... Hobbyking does have esc that will work , still need a couple of servos and a radio , just not sure if a 6 Chanel land/ boat radio or get a large channel stick radio would be better ... as always $$$$ is an issue . Work on the messy table as I fit cut and replace fittings and supports ... Smooth sailing to all... Bill G
Bom dia Wingcoax, If I want something pronto I go online to Conrad or Krick here in Germany and usually get the 'stuff' in one or two days. If I order from Turnigy/Hobbyking I make sure the stuff comes from the EU warehouse. Then it's usually here within the week. Most of the stuff has reasonably understandable instructions, or I can find it on the web. Learned that the hard way with a delivery from China that took several weeks and and then cost me a small fortune in German customs duty 😡 Model shops around Munich are basically model railway, aircraft or toys🤔 Such is life today! Cheers, Doug 😎
The HobbyKing ESC I’m using has the facility for water cooling and as it will be in an enclosed location without any free ventilation it seems sensible to utilise this feature. To keep the water circuit as short as possible I will put the pickup just behind the propeller and the exhaust on the stern but as the boat has a bulkhead just in front of the stern skin I need to make an access hole through it to allow me to secure the nut on the stern skin. I made a hole through the bulkhead large enough to get a socket on the nut and reinforced the hole with a ply plate, similarly I reinforced the inside of the stern skin where the outlet passes through it. When I was happy that the arrangement worked and I could attach the hoses and securing clips easily I glued and pinned the stern skin to the hull. The water pickup is a standard one that is readily available but it’s supplied with overly large and ugly fixing nuts, the inside one is of no consequence but I thought that the outer one needed smartening up so I put it on a threaded rod and locked it in place with another nut and put that into the chuck of a drill and used a file to re-shape the nut to a pleasing taper….who needs a lathe......😜 I had to reduce the height of the inner keel former as the pickup tube is not long enough to get a good fixing with the internal nut, as the inner keel is balsa I fitted a ply reinforcing plate to spread the load. The last ‘photo shows the location of the ESC, main battery fuse and receiver. The hoses will be secured to the ESC with spring clips throughout. I found that the silicone tube I use tends to kink rather easily if the radius of a bend is too small and I found it necessary to form a tight spring coil around the piece that loops the water back through the ESC to prevent this happening.
Hi All I use the Hobbyking car ESC's HK-45A, HK-60A SL and HK-100A which all use the same program card(HK PROG-CARD). I use the same setup for all my boat, only changing the battery setting for the 2s, 3S and 4S Lipo. 1 Cutoff Voltage for 3S=10.2 and 4S=13.6 2 Start Power Percent=5% 3 Advance Timing=4 4 Run Mode=2 5 Brake Force=1 6 Drag Brake Force=1 7 Neutral Range=1 8 Initial Brake Force=1 9 Reverse Force=1 It works for me.

Hi Charlie I have tested my 37" Perkasa with a brushless 3639-1100kv motor from Hobbyking, a 60A ESC, 3S 5800MAH Lipo battery and 37mm 3 blade CNC prop. It's dam fast !!!! https://www.youtube.com/watch?v=9fddqnbnlrQ Canabus
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
Thanks Steve. Looking forward to it and its challenges. Since my last message, I have made progress, purchased a kit from Cornwall Models.

Doug, Am using the HobbyKing 50A Boat ESC 4A UBEC along with their programming card. The diode explanation makes sense so will fit one. jbkiwi My battery -ESC and ESC -motor wires are short, probably around 4" each. The addition of capacitors as suggested is intriguing as have never heard of it before. Think it is easier to keep things together in a boat, whereas with an aircraft pitch trim becomes a factor. Am using 2S batteries with a 50A ESC, with the motor max current of 30 A. Have you any idea what size of capacitor I should use? The Tx/Rx combinations are almost infinite as the ESCs are programmable too. Just wish the ice would go so can experiment! Thanks both for your help, with this hobby you never stop learning.
