I've got a new US 120 lite in the box, and have ordered the carbon fibre push rods and titanium ends from central hobbies and the dubro heavy duty control horns from Dubro. The kind you just drill one hole in the surface. The servos will get ball joint type ends from Dubro. I'm setting it up with flaps and ailerons and moving the elevator and rudder servos to the back. No pull-pull for the rudder. Mounting my Zenoah G26 with Brisson muffler on a beefed and glassed firewall. Hope to get my stuff next week and start building it. My old 120 wing is still in the tree that ate it. boo hoo.

My son-in-law has the setup you're doing on his US 60. He has a OS 91 FS with the set up you want. It's really cool to watch him crow it in from about 100 ft up, straight down to the runway and land with just a few feet of runway. I'd like to get mine to do it.
