Well, I'm building a second one due to an unfortunate incident with the first one. I bought the replacement over a year ago and am just now getting to it. You may already be aware that Horizon appears to be fazing this model out. Looking at their web site some of the replacement parts are no longer available. I liked the way the first one flew and was really enjoying it. I hope the second one flies as well.
I'm a air operated retract builder. I've seen too many issues with the electrics. It's too easy to bend that actuator screw.
