Hello Mirce,

It's nice to see you building another favorite of mine. I wish you well.

I have found it is always best to have the retracts in hand before glueing the plates/rails in the wings. I actually bolt my gear to the rails before adding glue to insure they lay flat and it's easier to trim the ribs if this is required.

If you buy the Sierra retracts, you will not regret it. I consider them the best available.

Good luck,

Jerry
