Use these servos in 30pcnt SBACH with DLE 55. At 7.2 volts the servos
deliver exceptional performance in all maneuvers including hard 3D flying. Have well over 30 flights on these servos and they show no wear or problems. Highly recommend.Today May 20th 2012 I tested this servos on the cyclic of my Trex700E 3G FLS. Im satisfied with the performance of the servos, they withstood normal flight and some simple aerobatics. The price is worth for people to venture upgrathe the standard 6 volts servos , to a high voltage setup. This will allow you to eliminate the BEC.
For the Tail servo I decided myself for the new Hobby King MI servo rated at 0.03s and 4 Kg (Very amazing performance!).
My radio is an Aurora 9 of Hitec and I was able to notice a low voltage ( 6.4 volts) alarm on the receiver/servos battery (a Turningy nanotec 2.7 Ah). These only means that the servos draw quite an amount of current enough to pull a full charged 2S Lipo up to 6.4 V. But the battery recovers quite well after a hard maneuver. I would be worried of an brownout.
It only quite disturbed me the noise these servos make whie I was trimming my Flybarless system. One of my cyclic servos jittered once in a while but this did not reflect adverse while flying.
Overall satisfaction for the price is five crowns.
Im very happy so far because the servo head fits exactly to those from align servos. Im planning to use them as an upgrade of my servos on my TREX 700 3G FLS.I use this servo in my Hyper 8.5 Pro BL-conversion! It works like charm! It might be a bit over kill as a steering servo in a 1:8 buggy, but I don't care! :) Compared to the BMS660HS MG the BLS2209 seems much faster. I will upgrade my Hyper 7 Nitro steering servo from the 660 to this one soon!
