These are the perfect solution. Interference illiminating, optikill, LED to show ignition power, and adjustible voltage regulation. And on top of it all, Ed's customer service is the best.

I had two of these in planes that had crashed and I sent them in to him so that he could look them over to ensure they are okay to use on my next builds. He checked them out and did the needed repairs for no charge. And he will spend more than enough time with you on the phone to help you, in any situation you may have. He has team members that are also on Team Futaba, so they have lots of experience. I highly, highly recommend Tech-Aero products!
