Several crashes with 450 Pro FBL caused loosening of grip linkage ball thread and also damage the servo Gear/horns.
I am using MKS95 cyclic servos so I worried about servo damages. So I devised this mod. Some technic and hand work needed but great success until now. I do some hard 3D like tic-tocs but no problem at all. When I crashed, linkage ball braked and crumbled before the damage of grip bolt or servo horn/gears, and also I installed little tension spring preventing from swash linkage pop-out in crash situations.
I flew hundreds of times with this mod and got many crashes, But grip or servo's still brand now. I really happy with this mod. but you need sometime of handwork.
You need 2.5mmx12mm acryl pipe and linkage ball with 8mm bolt inside and secure it with JB weld. and penetrate 2.5~2.6mm bolt through rotor grip hole and fasten the acryl pipe. Size should be exact and minimize gap beetween grip bolt and linkage ball bolt. If you use 2.5mmx12mm acryl pipe with 2.6mm grip bolt it fastened very securely. I made and carry tens of this little parts and change after crash
