___________________________________
Flipping the Raptor 30 head.
(Before starting, measure and write down your pitch settings.)
1) Remove the head bolt (Page 12, No. 1).
2) Pop the oval links Page (11, No. 25) and mixing rods (Page 12 top, No. 4) loose at the bottom.
3) Pop the wash out links (Page 7, bottom, No. 8) off of the swash and remove the wash out subassembly. The links will have to be modified slightly. If you look closely, you will see they are beveled inside the “y” on one side. Use a file or sharp knife and remove enough material to match this bevel on the opposite side.
4) Turn the wash out subassembly over and slide it back on the shaft. Push the swash all the way up and tilt it to it’s full left/right/fore/aft position making sure the wash out links do not bind against the arms (Page 7 bottom, No. 7). If they do, remove more material is noted above. When everything is working freely, pop the wash out links and oval links back on.
5) Remove the lock nuts from feathering shaft (Page 11, No. 27), pop both double links (Page 11, No. 26) completely off, and remove the blade grips. Rotate the grips 180 degrees and reinstall the grips and lock nuts.
6) Modify both double links as follows. Remove a link from one end of each and replace with a standard length ball link. In every case I have tried, these needed to be installed with CA glue as the new links were a little loose on the threads. After modification, pop one end back on the blade grips.
7) Loosen the flybar control rod set screws (Page 11, No 4), rotate the control rods 180 degrees, and re-tighten the set screws. Since these are now not on the flat area of the rod, you will have to be careful to keep the arms aligned while tightening.
8) Remove both mixing levers (Page 11, No. 22), flip over 180 degrees, and re-attach to the opposite end of the flybar seesaw hub (Page 11, No. 21). Don’t forget the loctite. Pop the double links and long linkage rods back on.
9) Install the head on your Raptor and re-attach the wash out links and long linkage rods to the swash.
After double checking that everything is tight and installed correctly, you are ready to re-do your pitch settings and fly.

Hope that helps. Check that you did not forget anything.
