Hi LS"The ducati regulator doesn't have a reasonable service life; it burns up > fine at any temperature so the temp probably doesn't matter. > I considered putting a small computer muffin fan on mine but have found > it's just easier to keep Lockwood's order line no. handy in my cell phone > so I can call them up quick when it burns out. > I'm on my plane's 3rd one now (if my count is right) and don't plan on > this being the last one "What motor do you have? How many continuous amps are you drawing? I kinda thought if you keep regulator as cool as you can that if you obey 12 amps max. continuous that the regulators last for a semi reasonable time?Thx.Ron Parigoris   [quote][b]

Hi Lucien"> If it does have to charge the battery or power lights, etc., it's hot to > the touch when I get back to the hangar (until it burns out that is)......"For what it's worth Lockwood mentioned if you insist on asking internal generator to produce more than 12 amps continuous, besides needing to replace regulators, it burns up windings in generator.I installed a B+C SD20S alternator on accessary drive with a LR3C regulator:http://www.bandc.biz/index.aspxAin't cheap but a real jewel. There are some that mount aux alternator off back of motor on Europas that provide a faster spin. If your plane/prop will allow you could go with front belt driven ND.Ron ParigorisBTW I went with a switch from Flaming River mounted in headrest instead of using precious amps to drive a battery relay/solenoid.

Its a 912ULS. My current draw is about 10A max and when that occurs it's intermittant (i.e. I start turning things off and let the battery charge at that point). 



The regulator is just too light-duty to handle continuous operation at its rated power dissipation. Just needs heftier semiconductors in it and a bigger heat sink..... either that or move the decimal place on the price over to the left one spot to make the cost correspond to its quality
