AGFRC Digital High-Torque Micro Wing-Servo - 11.4KG CNC Thin Brushless Servo with Dual Ball Bearing & Metal Gear (A20BHM)

I tested the stall torque and only getting 8.15kg-cm at 8.4V and with a bench power supply that allows for up to 3.2A... ~70% of what's rated (11.4kgcm).

This servo is VERY similar to some high end name brands. Got plenty of torque and is pretty dang quiet. Overall, this variant looks pretty cool with the colors, it's the same as it's standard variant as far as specs. It performs really good, it's fast, and torquey.

I like AGFRC servos for their programmability and their feature set including both Futaba and Sanwa SR/SSR capability.But the A20BHM is not a good servo for any application without a servo saver (I can’t really find one in this scale), or any application probably outside of low speed crawling.My A20BHM did not last long, maybe 3 battery packs, in a FMS Smasher truck. I’ve seen NSDRC and Pro Modeler servos in this size last much longer.I’ve deducted two stars for the weak gear set. The servo really shouldn’t have broken so soon.I’ve deducted another two stars for difficulties finding a replacement set of gears. There is no replacement set for the A20BHM listed on Amazon. The Amazon support link from the order page is dead, leading to an invalid AGFRC site with a HTML 404 error. There is no contact information on the AGFRC site, no email, no phone number, no ticket system, nothing. I’m now waiting for a reply from what I believe is the AGFRC international site on Facebook messenger. The away message for the Facebook AGFRC page was in Mandarin, so I don’t even know if I contacted the correct page.I’m hoping I can get a replacement set of gears under warranty, for a servo that is only a few months old and with just a few battery packs on it. I’ll update my review after I hear from AGFRC.

These servers are great for thin wings with good torque For my Nitro ducted van old school jets

This is a strong little servo, I run it at 5v and it still has plenty of torque!
