700 Main shaft bearings

[bish]

Started the rebuild of our 700 tonight and the main shaft bearings are shot to bits again first set lasted about 15 flights these have done around 30 flights do we replace with standard or does anyone know of some longer lasting upgrade bearings?

I got a set cheap if you want.BNIB

TBH I looked around at the time I brought those sets and for the cost and ease of just changing the whole units I went with the originals.

Bearings will always get shot to bits in any crash Bish.

Its standard practice in my fleet to replace them after a crash.

Ben thing is they're cheap enough £5.99 i think but its a pain if they keep going was just wondering if it was worth fitting better quality one's

Thing is Rob the last one's went notchy with no crash i only noticed as a result of some routine maintenance,would you just go for standard one's mate?

[robgt]

Yeah, I would just stick with the originals.
I don't think I ever changed the main shaft bearings on my 700 while I owned it, and that took some hammer in the air (but not crashed).

Maybe you got unlucky with a bad set of bearings previously?

Fingers crossed

RCbearings.co.uk, For a friction free RC! put the size in the search, delivery is £1 and normally next day. Ive just ordered some main shaft bearings for my N9 as it goes

[glen_j]

i replaced the quite a few bearings in my 700 with the ones from rc bearings when i got it second hand, i also had a spare set of bearing blocks that i've replaced the bearings in for when the time comes, seems a waste to keep buying the blocks when its just the bearings that need changing, takes about 5 mins to change the bearings in the blocks

the bearing code is 6901ZZ they're 80p each on rcbearings

I found the bearings for my 500 main shaft were less than half the price of the Align jobbies, and they are reputed to be a better bearing too.

[glen_j]

yeah i found that too i very rarely buy the align bearings
