Comments: As above stated are not true statements. These were due to failure of incorrect mechanical setups. Align makes a really good servo for the money and many in the hobby use these servo's without failure unless due to a crash. I personally have had zero issues with them and yes when i crashed they do strip sometimes but the rebuild kits are pretty cheap. Strong and fast servo's and performance achieved at half the cost compared to higher end servo's with similar spec's.

Comments: these servos work fine while operating. the only problem is that they posses quite some slop in the gear, which resulted in me having to adjust cyclic trim on a random basis. the trim seemed to be different from flight to flight...
besides that they work fine, are fast and strong.
