Having problems finding a drive linkage.
Has anyone built the Marina R/C by Artesania Latina? I am and the building part is no problem. I cant find drive linkage. The ship kit came with the stuffing box with prop and shaft. The company I

Re: difference between wound and permene
Donald...you have misunderstood what I was saying. You are right on some points...the battery amp hours dont change, HOWEVER, there ability to deliver 200 amps does and some deep cycle batteries dont

Re: difference between wound and permene
I came into this forem with the thought that high voltage systems would be the way to go and actualy did several design looking at several brushless technologies to try to come up with a more cost

Re: AC Power Use
You got it Larry,<br>When you discharge your batteries it's hopefully not to 100% DOD, but counting the losses 240 ah is a good number to use. The rest is correct and should work out to around a buck

Re: AC Power Use
OK, guys, check my math on this.<br>Thanks for the suggestion, Joe, although I have the problem that my charger is automatic and therefore its draw varies over time and Im usually not able to monitor

Re: Great chat - whens the next one...
Corrosion resistance and resistance to electrolysis can be designed into the system by electically isolating the system. On PM DC motors the torque curve is not a curve at all but instead they have a

Re: difference between wound and permene
Technically speaking.. PM DC magnet motors for 24 or 36 volts dont work either because of the current required to make the torque. But then too,why would you want to when higher voltage motors are so

Re: AC Power Use
Hi Larry,<br>I beleive the two numbers you have to find are:<br>Charger efficiency (in %) and Battery charge acceptance (in %). Normal numbers look like 15~20% loss at the charger (Heat) and 25% +/-

AC Power Use
If I know how many DC amp hours at 36V I need to replace into my battery bank, is there a way to calculate the number of AC KW hours my charger will use in order to do

A 27 inch ULS outboard has been on board 5 years after 15 years with sails only. It was added at purchase to negotiate marinas and assist anchor retrieval so the 9.9 HP is the bare minimum and not to

Re: Great chat - whens the next one...
I believe that the speed limit you refer to is based on mono hulls and also is limited to displacement hulls. I agree that cats and even tri hull will have high speeds. I don't think this area has

Re: Great chat - whens the next one...
You and others are probably all asleep - i'm in my lunch hour. Maybe i'll have smoko (tea-break) when you next chat. I read last 120 messages - only saw one "Cat" reference. I have a 50 ft Atlantic

Re: Great chat - whens the next one...
We can do a chat in a number of ways. One is for someone to volunteer to lead a specific topic - another is to just set a data - see who shows up and discuss what people want to discuss. I am open

Re: difference between wound and permene
There are various kinds of "wound field motors" first of all there is the simple shunt wound motor and it has torque charcteristics similar to a PM DC Motor The only real difference is that you need

difference between wound and permenent
Looking at DC electric motors, I have come across two very different types of motors, the wire wound electro magnetic type( a whole bunch of manufacturers), and the permenent magnet type (EWheel
