| Subject: | Re: RV4 Left Wing Flap Push Rod |
Jerry, I would just like to agree what Hal has said and emphasise that ANY
damage to the push rods is a reason to discard them and make new ones.
When I made mine up , new, I realised just how fragile they are. They rely
on the 'push' being up and down their own axis. Any side pressure risks
kinking them which would lead to their collapse. Many builders have gone to
the hexagonal pre tapped ones that VANS supply for the -9, but VANS
reassured me that provided they were made to design, AND DID NOT BIND ON THE
FUSE, the ones in the plans are fine.
Cheers, Steve.
