I've got some savoxx in my rc cars, 50cc yak and YA f15 so far I have been very impressed with them. I've got the 1258tg
And 1256tgs. The 1256 is really fast def need to use some expo, the drive trains are silky smooth, I dare to say even smoother
Than my 84 and 8711s. I'm actually planning on going with full savoxx servos on my new MBA tornado. What really sold me on them was seeing them on mine and my car buddies 1/8 scale buggies and monster trucks. Watching an 8 pound car cartwheel for 60ft at 40mph and keep going several times was very impressive. I know cars have servo savers but I've still seen other brands of servos strip after a few similar incidents.
