Ok, I've been pretty hard on Robart, both here and in my conversations with them. I was really disappointed in the fact that i had problems with a $650 set of retracts before I ever got them mounted in the plane. Then after I got them back, I installed them believing that all my issues had been resolved. I posted the video that showed them working, but still with the catch. The first time, it was bad enough that they wouldn't carrry the weight of the wheels without binding. Now they work well enough to raise and lower the gear. I put them in and sheeted around them. I was raising the gear to make sure I has plenty of clearance in the wheel well, and one of the actuators broke internally. A frustrated call to Robart got me in touch with their technical support. That was on Wednesday afternoon. My replacement actuator was in the mail today.
Even though I've had some bad luck so far, the customer service has been excellent. I'm confident in the structure of the gear, and now maybe I've got the gremlins worked out. I'll post a video and more of my experience tomorrow.
