Just replaced this after my old one (decades) had quit working, then one day decided to overcharge the capacitor and explode mid taxi. Luckily I was close to home and could remove it from the system and fly the short hop home. I put a new one in with heat sink paste and all is well. We shall see how long it lasts.

My old regulator/rectifier literally Blew up. In flight So I ordered this one from AircraftSpruce for replacement Very fast service, installed, checked Voltage ,as is Perfect Back flying again

5 stars is probably not high enough. Great product only to be surpassed by AirCraft Spruce service.

Order came very quickly, my plane is back in the air with the new regulator that is working very well.

Easy install. Works perfectly on my Rotax 503.

Very fast service & easy to order online

Pure DC! Using cigar lighter adapters, this powers the internal batteries of my ULs radio, GPS, EIS and strobes. No need for a heavy battery in my electrical system!

Nice quality and works terrific for the Rotax 447 on my trike. I called the company tech support on an installation question and was told they would call right back. They called right away and answered all the questions I threw at them! This would be a wise purchase for your electrical system.

My Key West voltage regulator has been in service for 18 years on my Rotax 447 Ultralight, well, that is until today. Sitting on the ramp at a fly-in dinner I was warming up the engine when there was a loud bang followed by a fair amount of smoke and some bit of debris in the cockpit. After shutting down the engine it was apparent that a capacitor in the regulator had exploded, blowing off the rear side of the regulator. This seems to be a rather common failure. Im just wonder if the sun, beating through the windscreen and directly upon the regulator factored in to its failure? Ill be ordering a replacement soon.
