Congratulations on finding the ARF, I hope to get mine finished and in the air soon. Assembly is officially on hold until the 25th because my son and his family are visiting for the summer vacation.
I too had thought about using two servos on the elevator but then I remembered that the Super Stearman (really the same size aircraft) has that same setup and it has been working fine. I have a hot enough solder gun so I used that rather than JB Weld. What I did was put on both wheel locks with solder in middle. If I get a chance I’ll try to send a photo.
While I am rambling with opinions, I have all of the 3 cylinder Saito radials and the way I calculate how they will perform is only count performance from two of the jugs. The 90R3 works good for a 60 size aircraft, the 170R3 works good for 120 size, etc. I know I have the 170R3 on the Super Stearman and it won’t do 3D but it climbs until I cut the throttle and I usually fly it around the patch at half throttle or less and it is a 15lb aircraft. The ModelAviation.com review used a 95AX and said it was plenty of power. I am not making recommendation here only telling how I chose the Saito 200R3 for mine.
I appreciate your thoughts. It sounds like 2 servos will not be necessary. It will be a little while before I start this one, so I have some time to decide what engine to go with. The Saito radials are tempting.
