There's a few videos out there, threads here on forum and instructions on gong site how to sand the TE on the wings to eliminate whistle.
It takes me 20 min. You need sanding block, 180-240-400-800 grit wet /dry ( black) sandpaper. Water. ,
The gong wings are very solid construction, better than most. And price is so competitive, that I'm willing to sand them.
My friends m pro clear didn't whistle, but my Mpro and Veloce did. Now totally silent.
Hade one wing of 4 from Moses whistle, due to pin holes in clear coat on surface of wing. That was harder to fix. Had to paint whole wing. And it cost 2x the gong.
About ride. I have been on 90 cm mast almost 4 years, so switch to 100cm could be part of increased difficulty. Feeling was that it was less roll stable, but flying foot switchs were not a problem. Too early to tell whether Veloce is preferred over m Pro.
didn't want to give the impression I am lazy, or worse, that I feel entitled to an absolute non-whistling foil from Gong.
It's just that I am, unfortunaly, really – but really – bad at manual work of this kind, and would never approach it on a new foil for fear of damaging it.If it whistles, than it's a problem as it'd force me to do the sanding with unpredictable results
I'm really considering the Gong (and I like being a bit against the grain: lots of Moses at my spot now...).
Can I ask a couple of other things?
1) how would you rate the Gong mast vs the Moses, i.e. rigidity, finish, longer term reliability?
2) have you tried mixing Veloce Wing with the Surf stab? (there are no veloce stabs available anymore on the Gong site )
Thanks again for sharing.
