[NSRCA-discussion] Boca bearings for YS, are the Econo ones would do?

[Vlad Camaev]

Guys,

I have to replace bearings in 2 YS (110 and 91), one due to rod failure and another just disintegrated and put two it's balls into send like pieces.

Boca bearings have 6 types from $12 to $78 for a pair.

Are the "RC Engine Econo Power Bearing Kit" sufficient in quality?  
Where would stock YS bearings rate? Central hobbies would have a pair for about $30.

Thanks,
Vlad
