R90se, That's a first!!

[Tripler]

Maidened my New R90se yesterday and something happened I've never had happen before
Everything seem ok for about a quarter of a tank and then the tail started to play up,, became sloppy and then locked,

Lucky I was just hovering around for the first tank as I normally do for a new build maiden, I was able to land ok.

On first inspection I couldn't find the cause then noticed one tail blade grip looked further out from the hub,

Took it apart and the outer bearing shells had pulled off the inner!! never had or seen this before?? anyone else seen this?

Put them back after snapping the bearings back together and flew it, expecting it to happen again which it did,

took it apart then noticed the bearings covers are black one side and red the other,
thinking this may be an issue for some reason, maybe the way they are assembled, checked the manual to see if there was any mention of this, which as I thought there wasn't,(having built countless rappy's in the past)
I reversed them and flew it again. Nothing happened after a full tank,

I will be changing them but this is certainly a first for me, wondered if any other new 90se owners have had this problem?

As no one has written any replies or commented on this I guess I must have been the only one out of the 30 kits that fast lads sold with duff bearings

I had these bearings in my x50, iirc they are a thrusted bearing which works one way only. Can't remember for the life of me which way is which but download the x50 manual if it doesn't say in the 90se manual.

Thanks I will check my x50 manual, and my x50 as can't remember setting them on that??

the later rappy 50 kits had these bearings
i'm sure my x50 has them
incorrectly fitted they will fail

Sounds like they are angular bearings. Elyq used these bearings and they have to be fitted the right way round, on the elyq the red side went towards the tail hub and black side towards the tail blade grip.

Even the later raptor Titan SE had these bearings

red side in black side out

hope this is of help?

I have flown mine four times now with no problems I did think do they go a certain way round cant remember what way I put them in so I better check them just in case.
