Calflyer,

Thanks for the tip. I used a technique from an old Hangar 9 Cub wing I have stored. The servos in that wing were mounted on plaes with blocks so they could be hidden in the wing. I used one of those plates as a template, and the blocks to mount the throttle servo nice and snug on the fuse side. A little grooving gave the linkage a perfect shot to the throttle arm with zero binding.

rcfury,

After using 30 min epoxy and triangle stock fillets on the tail, it stress tests pretty strong. However, like you, I don't want to take chances so I will be custom making my own struts for the tail. As for the Saito 120 fit, inverted should be fine. I was amazed at how easily the fuel tank and carb lined up in this position. If you choose to mount it sideways your going to end up with a butchered cowl. The 120 is larger than you might think and the cowl isn't. An onboard glow driver is essential if inverted. It would be unwise to try to reach around a 15" or 16" prop each time to connect and disconnect a glow stick. After a proper break-in, I have tested the 120 inverted and it starts easily and purrs like a Lion (kittens are weak, the Saito 120 is not!). turning the motor mount to inverted is simple as well. Although mine is not perfectly aligned straight down, it has the proper thrust angles with a couple of washers under the left side mount screws. I used two of the existing mount holes and redrilled the other two. Removing the blind nuts is fairly simple as well. Make sure that you beef up the firewall with traingle stock in areas that are not affected by the mounting screws. Also, initial CG tests show the battery heading for the tail...way out.
