Despite what John says I'm gonna post anyway.

First used 1256's on an Elan tail to test them out with no problems. (100 odd flights)

Next used all Savox on my 1/5th L39 now on 48 flights, again no problems.

New JL Viper with four flights, again all fine.

I had two 8511's fry themselves on an F16 tail and replaced them with 1256's, no problems since (no regulator fitted)

Currently installing them in a small F86, in other words I trust them implicitly.

As has been stated they also make the Align and also the Spektrum servo's I believe.

I recommend them.

Gary.
