Default Hitec regenerative braking

Stumbled across this feature and it got my attention. Anybody using this? What ESCs are compatible with this?

Wow! I just read up on this after seeing your post. Novak started doing regenerative braking in their ESCs back in the late 80s- early 90s, which makes sense to use the braking energy to recharge the battery. I'm not really sure of the usable benefits of this in a servo. I wish Hitec had more info to explain this readily available on their site. I did however find this bulletin:

June 2014: Brushless Servo Service Bulletin

While compatible with most radio control devices, the regenerative braking feature of the HSB-9XXX series servos may cause a problem if the device cannot accept a backflow of current. The types of devices that cannot accept this backflow are: Voltage Regulators, Power Safe Receivers and certain BEC circuits whether stand alone or integrated within an Electronic Speed Control. Check with the manufacturer or the Hitec website for a list of compatible models. If your device cannot accept a current backflow, then you must install a PAD (Power Absorbing Device - Hitec PN# 55756) as described in this manual. A PAD is included with every Hitec brushless servo.


I couldn't find a compatibility list or other info on this in the listing with the servos. Although with the included PAD the servo will be usable on most systems even if you can't take advantage of the regenerative feature. I love Hitec servos. They have never failed me yet.
