Got a question for some you pro builders. I am on step 16 of the manual. Frame assembly. I have heard of guys wrapping the bearings with tape or even shoe goo to make a tighten fit in the bearing housing. Any opinions on this and is it necessary to do so? Just wondering what others ones have done that have already built this kit. I saw on heli freak site where finless bob likes to use shoe goo. And I have use this on my trex 500. Just looking for some advice! thanks,

Brad

I'm no expert builder,but I do know my way around old Raptors fairly well. I really see no reason for anything to help hold the bearings. I have had some pretty bad mainshaft bearings,and they never spun in their housing. The X-50 shouldn't be any different. If a bearing is bad enough to spin,I really don't see how Shoe Goo would hold.
I can see where tape would work. But it might also make it squash the race where the bearing fails quicker. Or if you ever replace a bearing,the second one might not fit as tight.
Just my opinion

Thanks, I didn't think so, but just wanted to see what others was using. I just noticed during the build that the bearings are not over tight fitting in their housing's. So I just added a small amount of shoe goo on each bearing just for the heck of it. I have used this method on my trex and it worked fine. Shoe goo doesn't get hard, stays pliable and is easily remove should a bearing need replacement. I saw add article in RC-Heli where they recommended using shoe goo to secure the muffler bolts over using locktite. According to the article blue locktite is not fuel proof. But shoe goo is. I may give it a try their also. Finless Bob recommends it though. He definitely has build his share of heli's. Should account for something. But like most have said it isn't really needed.
