Hey Roger,

The old carbon fiber retracts actually worked pretty well. As time went on BV upgraded a few parts to aluminum for more strength. The downlock link and strut block were the two main upgrades which made life great.

If you were to upgrade to some solid aluminum units keep in mind the flex plates are designed to break away as well. By doing this it of course brings the possibility of damage to the wing to a minimum. I would upgrade to the aluminum parts and go with it. The system worked well as designed.
