thanks for your help. I heard from a local R/C store person that it'll be 'okay' with couple msising teeth on my heli. I guess he didn't know what he was talking about. This may affect my investment in HBK 2- may be cancelled and used for repair/upgrading Belt-CP. Choppersrule, thats exactly what my gears look like. I guess I'll spend another 20's and 30's into my first heli :'( . [Say I can learn from experience.]
