Are you using UAV bits' strong arms and have you noticed any cracking or issues? I have purchased and installed a set on one P3P and am installing another set on my other P3P this weekend. I am just wondering if people feel they are having success? Or has anyone had issues even though they have strong arms installed? I have just seen so MANY threads about the stress cracks (including Chris' terrible incident with the motor mounts completely breaking off) that I am curious how effective the strong arms are. I have not seen anyone with strong arms say anything less than positive - and I am not really digging for dirt - just thought to ask this question.
