I have 2...
One with a OS 52 Surpass...flying over 2 years...

New one with Saito 72....
I have a pull-pull rudder (Dubro)..and for the elevator pushrod, I am using Dubro fiberglass pushrod...
Using Hitec 605 Hi Torque servos on elevator and rudder...

Two things worth mentioning here...

A) Reinforce the landing gear block. This is very easy to do as I just took some triangle stock and epoxied it inside...

B) Like anyone who has flown this plane has mentioned...start with the CG as close to the nose as recommended and low rates on the elevators because she WILL SNAP....

Also on landings...once you setup and are in line with the runway, allow the plane to settle in and not apply too much up elevator...except when rolling out...
