I purchased two of these and they look like a good unit but it appears that it cannot be turned on from your transmitter. I may or may not use these as I have others that are able to be activated from my transmitter. (Posted on 3/19/2015)
I used this in an Ares Gamma 370 Pro, a large foamy. 39℉and 15 gusting to 20 mph winds. I have 2 identical aircraft but, 1 with and 1 without the S3. Got the one without in the air and the wind had greater control than I did. I considered not even trying the one with the S3d but, I did. Best flight in a long time. The aircraft was as stable as if it was sitting on my kitchen table from the time it left the ground till it made a normal landing. I am ordering 2 more today!
