Madstad for F6B

[d-shark]

Well I put a call in to Madstad and was advised that sometimes the shield edge is cut sharp and the edge is not rounded enough.
Soo I pulled out a roll of electrical tape and ran across the leading edge and went for a ride. Sure enough NO WHISTLE.
I did reach up over the shield and remove the tape at about 50 mph (not advisable) but wasn't able to pull it off slowly to see when the whistle would come back. So if you have a whistle this test may be worth a try for you...

If that is the cause then it would make sense why some seem to have the whistle worse than others, Manufacturing Variation. I checked the edges of my shield and they are fairly smooth all around. Did Madstad happen to mention what method & material they use to round the edges (a very fine emery cloth perhaps)?

Thanks for that input.

I will be calling tomorrow to let them know my finding and go from there..

They heat the edges with a small gas torch.
