FLASH HOBBY50kg 14V Waterproof IP67 Digital Brushless Servo Motor with 1/6，1/8, 1/10, 1/12 RC Crawler Car/Robot/Boat (180°)

I put this in my trx4 running it on 11.1 volts. Now it's by no means a 50kg servo that's for sure. However for the price point it's super fast, fairly responsive, pretty strong. I have servos that are more than double the price of this one and it they're definitely better. However, for a budget direct power servo, you can't go wrong. I would definitely buy another if needed.

Great servo for the money! Comparable to my Nsdrc and shift direct power servos. I already ordered 2 more!

Unit is powerful and fast, was able to use with 12 volt ok. Added an arm, but that decreases power 2 kg for every inch added, but compensated with counter weight.

UPDATE:After about three hours of use, this servo developed a shudder. It's still working but it will either die soon or stay unreliable for some time, and then die. It's not been subjected to anything all that strenuous.I'm having a replacement sent and will see whether this one also poops itself after just a few batteries worth of use.HUGE upgrade over the included servo with Axial SCX10 iii. Vastly improved the driveability of the truck.I moved to a Radiolink radio w/ telemetry so already had an easy way to branch power off the 3s battery, this seemed like a no brainier compared to getting an external BEC. Servo seems pretty happy on both 2s and 3s direct power, which is nice.No complaints. I'll be getting another one of these should a build/RTR need one!Not sure why they still include those goofy generic servo mounting screws/grommets/bushings that I'm pretty sure nobody uses, but I guess it can't hurt to have.I'll come back and update if it dies after just a few runs. Hopefully not!

Bought one of these and is outperforming some of my higher priced direct power servos. Definitely going to be buying more to replace the others as they die. Gunna keep a couple on the shelf for spares for me or friends.

The media could not be loaded. I never write reviews on here but I build comp crawlers and I would compare this servo to a $120+ brand name servo. Running it on 3s directly from the battery and it has a lot of torque and speed, and best of all, it doesn’t buzz. It has enough torque to move a 7 pound crawler from left to right and really get yourself out of a bind just from steering. Axel breaking power. I wouldn’t run this on 4s (14.8v) unless you’re using a BEC set to 14v or lower. Definitely buying again when I start another build so I can save some money and get near the same performance. Remember, it’s a direct power servo, so you need a way to plug the JST into the battery via an adapter. Zero brown outs and stoked to tell people I only spent $57 on it.

Fast and has alot of torque. This is going to be my new go to servo.

Whines a lot
