[Titanaircraft] Re: Vibration on rollout after landing

LS, Randy, and Tim,
Thanks for your replies. I have a Tornado 912 with go cart brakes
and fiberglass mains. The source of the shake is in the mains.
I'm sure part of the problem is the cheap tires. Yet, the problem doesn't occur on takeoff, just landing. I, too, hold the nose off
the gnd and use full flaps as an air brake. But, once it starts
shaking, it continues even after the nose wheel touches down and it
reaches approximately 20 mph.

Feels like the wheels are going to come off sometimes. What I've learned is to go to full flaps as soon as the nose settles and use aerodynamic braking to slow things down and stay completely off the brakes.  It's not a problem on grass as the need for brakes is minimal under those conditions. You will probably have noticed that there is little or no shaking on your takeoff roll, so the balancing effort isn't the solution.
