Hi Bruno,
I only tried to throw in a positive in what was starting to be a very negative tone in this forum. I did recently have a frustrating experience with Robart's new electric retracts for the ESM Corsair. After three different actuators and lots of shipping and emailing back and forth. We (Robart and myself) gave up and went back to the pneumatic cylinders. Now, Eric, let me send back the whole electric controller, the actuators, in all, over 250.00 dollars worth of stuff. He gave me a credit for what I had in them. It was not their fault either. I believe it was the airplane's or my problem. I've seen other ESM Corsairs flying with the same electric setup in them and they work fine. They've gone out of their way to treat me in a very respectful and supportive way. I'm not gonna say anymore or reply anymore to this forum.
