I have 2 sets of Robarts in my warbirds and selling a new set that I bought for a tp Zero that I am not going to build. I have had no issues with the Robarts. I have over 2 years in my hanger 9 p-51 set. I have replaced the airframe after I put in the top of the trees and it didn't hurt the gear. The gear work great. I also have the Down and Lock conversion on my Skygate Hawk. I did have one motor go bad but Mitch stepped up and took good care of me.

The Robarts are mostly made by D&L.

I have a set of the Boetech in a Lighting and they seem to work just as well.
