For all having a problem with elev. flutter.

I did the following:

I Have the older model with wood push rods.
I used 4-40 wire in place of those supplied.
This reduced the flutter but did not stop it.
I then added a 1/8 ply cross brace on the first former behind the wing saddle. I drilled a hole
in the brace about 1/16 larger than the wood push rod. this stopped the push rod from flexing.
I have since flown the F6F six times with no flutter. I am using a MAGNUM 120 AT FULL THROTTLE.
