New to the forum, glad to be here. Quick question: in higher wind, the front Micron's lower spreader can flex significantly (due to bridle pull). Doesn't affect the stack's flight, but has (twice) led to the spreader popping out of one of the edge t-fittings (though well-seated at takeoff). Best to ignore, or could the spreader be upgraded to a more robust material?

Cheers.

Actually, you should stiffen up the whole frame or make a ghost frame.  It's not the spreader flexing that's the issue as much as the LE flex.  You can start by going to a 4mm solid rod for the spreaders and spine but a full 4mm frame will help a lot.  Also making a longer bridle makes a big difference.  Adding 2 inch pig tails at all the connection points will lessen the compression load on the rods a lot.  Remember, as the tow point is pulled, the force on the bridle tries to pull the frame connections together.  This compression force on the rods is what causes the rod to flex under load and what you are trying to counter either by using stronger rods that take more force to flex, or changing the angle of the bridle lines by making the bridle lines longer.

Excellent suggestions, will tinker with both ideas. Trying to interpret what’s happening from 100’ away is... challenging. Thx!
