Default RE: CMP 120 size Cub - Assembly

Installed aileron servos in wings. JR911 mid-size servo. It's a coreless - ball bearing - nylon gear - servo with about 45oz torque at 4.8v. I'm using a 6v battery, so I'm guessing they'll be around 50-53oz torque.

This ARF has been lying in some guys garage for 3 or 4 years. It's missing the elevator pushrods and a few other bags of hardware. Ended up peeling the covering off the bottom of the plane and cutting all the pushrod tubes out. I hate wire pushrods anyway, but only having 1 in the bag when I need 4 ............ I'm not messing with it. Cut 'em out and put some other pushrods in there. I've got one in place at time of pics. I got one more pushrod here and will have to run off to the LHS and buy 2 more tomorrow.

I wish it didn't look like a snake running through the fuse, but thats where the holes laid out and there's not much room to drill new holes unless I patch the old ones first. Thats what semi-flexible pushrods are for, right?

I'm going to use cheap Hitec 311 servos on each elevator half. They're new and will do the job.
