Victor Alcocer Verified Owner Sunday, Aug 17 2025 (6 weeks ago) J&T Bearing Co. Sworkz S35-4 Aluminum Radio Stiffener w/Carbon Cover Price was great with discount. Unfortunately, holes on the carbon fiber cover do not match with the plastic tray. It interferes with a lip around the tray, I had to dremel out some material from the tray. Also, the aluminum piece doesn’t seem to fit right. The aluminum piece thickness where the servos mount will raise the servos 2mm which will raise the center of gravity. View all reviews
