Just to add to this for others benefit to think about maintenance , I don't need to rehash about "Fry Eagle"!
A couple a weeks ago at my event one of the guys brought out a beautiful BVM F100 that he purchased from a very famous scale modeler.
The model was test flow earlier this year by a very competent Jet flyer with no issues.
Anyhow he proceeded to fly and he was having tremendous issues at high speeds turning the model, so he throttled back and brought it in for a successful landing.
He proceeded to remove the tail section to inspect the servos and linkages, what he discovered sent chills down his spine.
With the BVM there are two servos driving a common shaft for the flying stab, the servos were high torque JR types more than up to the task.
The issue was one the 4-40 threaded rods that was epoxied into the carbon fiber shafts broke at the threads, so only one servo was driving the stab.
Long story short, the air frame was talking to him, luckily he listened and avoided a major crash!
