HK 500e FBL Main Bearing Plates and a Bad One-Way Bearing



The new bering plates came in and I went to install them today. I found the plate to be 5mm too narrow! It's always something...



I had some 3 mm plates of very dense wood and use them to make the gap. 
Worked fine, very solid as the wood is so dense.





Tuned up the 4 blade head.



Now this was curious. The lightest blade was the "heaviest" on the balancer. It weighed in at 56.7, and on the right that's the heavier one at 58.2! I rechecked all the weights and they are real. The blades CG are all about the same. I have no idea why this is. So I balanced them all to the "heavy" blade.



I had planned to use 450 size blades before I realized that the grips only fit the 500 size. 
I may have to fly her 6S, fortunately have plenty of them.



She is all set! But, wait! There's more! I took her out to check her tracking and she swings the big blades fine, the tracking was perfect, and she was acting balanced. But, the one-way bearing is shot and slipped with the extra weight. It's the original so I am not surprised.


I ordered a whole new main gear one-way bearing set so its all fresh, from Amainhobbies. good price, great shipping option.
