hey guys i'm just wondering if all you guys bother balancing your props before you use em. i use all master airscrews, the plastic ones and i havne't balanced one yet mind you i havn't been flying that terribly long. i just replaced one on one of my planes and ever since then it seems to be vibrating and i'm assuming thats where its coming from. so yeah, just wondering if all you guys balance yours and if you do if you need a special tool or something. maybe i can make something hmemade.
