Theta Servos Razor-DH1 Brushless Low Profile High Voltage Servo
It bragged about being adjustable with an app. Ya! Not so much. Thankfully my radio has servo adjustments. I could not get the app to work for me. Seems like they are still in the process of getting the app up and running. I made some adjustments on my radio to get the servo to work to my needs. Performance is so so. Fast, GLITCHY till I added capacitor. Time will tell.
It’s a fasttech product so I don’t have much faith. I didn’t know that part till I did research of course. Looks cool. But the Dh1 is all black not like the aqua in the pic either. Hope it holds up. Drove mint at the indoor track.
