REFLECTOR: Flutter testing

[John Abraham]

More often than not the vibration that you feel on climb out is your tire slowing down.  This happens a lot after you have done a few dozen landings even after balancing the tire.  If it is out of balance the same spot hits the ground every time on landing which makes it worse and worse.  Some people with FG aircraft have put a strip of orange silicone baffling material on the wheel pant to prevent it from spinning.  This also makes it slow down faster.

 

Our trainer as you can imagine, or have been here for it has this issue quite often with the amount of landings we do.

You should visibly see any buffeting on the canard.

 I am continuing my flight testing and have been doing some flutter testing. What I have been doing is 

whacking the control stick to the front then  back then left then  right to see if I can induce flutter. So far no flutter up to 165 knots.

I hate this part of the testing the plane is so responsive so when I wack the stick the plane does an very abrupt move.

Bang my head once .  Ant one found a better way to induce flutter ?

 

Second thing I have noticed at climb out at around 90 knots and start a bank turn I get a small vibration I think it is buffeting of the canard 

any one else have this happen?
