Attention!
Apparently there has been a bad production run of main blade grip sets for the V200D03 coming out of Walkera recently.
I ordered a set of blade grips from Wow for my V200 around the first week of May. They turned out to be defective. The bearings on the rotor head side of the grips should be flush with the hole in the grips, which they are. However, the bearings on blade side of the grips should NOT be flush with the hole and they too, are also flush with the hole. The bearings should be recessed approx 1.5mm to 2mm inside the grip, thereby preventing the heads of the feathering shaft screws from sticking out, which these grip do. The bearing aren't pressed in all the way and won't go in any farther and actually appear to be stuck inside the grips. I've tried removing them to try a different set of bearings and ended up shattering the bearings trying to get them out. Another friend of mine also said he bought a set of blade grips from Wow that had the same problem. Since Wow or Jag didn't have any more in stock, I had to order a set from HK, which took 2 weeks to get here. They showed up and they too were defective. Same problem.
Then I found WalkeraHelicopterSupply.com and met Dave. Dave was kind enough to check a set from his inventory to make sure they were good. After he confirmed they were good, I ordered the set from him and did not have any problems installing them.
There is obviously is a bad batch of these grips coming out of Walkera, so beware."
