Waterproof 7.5kg High Torque RC Micro Servo Metal Gear Digital Arduino Servo for 1/18 TRX4M TRX4MT Redcat Ascent-18 Losi Mini LMT 1/10 TRX4 SCX10 RC Crawler RC Car Plane Boat Robot

Good little servo. So far no issues with about 25 hours run time.

For the price, Hobby Park servos do a great job. It seems stronger than the Injora servo that I’m replacing because it was struggling to move the tires. The Injora servo horn is a direct fit also. If you’re on a budget, this should be a servo to consider. It’s definitely doing really well.

i am using this servo for an IOM (international one meter RC Sailboat) and it is working well after 6 months, strong enough for the high wind days

Great small servo, fells good quality and the torque is good for a 1/14 rc truck (RLAARLO 1/14 truck old model or WLToys 144001/144002) with a 3D printed servo mount

A little bigger than traxass 2605 but works great

Priced good, very heavy and feels high quality. The servo has plenty of power and speed for my losi mini T 1.0

Overall, decent servo, especially for the price. However, I’ve had two of them fail in conditions that should be survivable for something rated IP67. IP67 should— in theory— be able to survive submersion, up to a meter, up to thirty minutes. I did the drive shown in the pictures, and shortly afterwards, the servo began to stall arbitrarily, then devolved into random twitching before I unplugged the battery. When I got home, I removed it from the muddy truck and tested it in isolation on a different receiver; same behavior. I then disassembled it to see if maybe the reduction gears were binding or something; nope, the motor/electronics seemed unable to find center once they moved at all. So yeah, while disassembling, I realized it isn’t sealed all that well. The wiring is sealed where it exits the case, and the front of the case has a gasket, both of which seems to work fine. However, the rear of the case has no such gasket, leaving the small PCB inside potentially exposed. There is plenty of sealant internally on the back of the motor & gearbox, so they are safe from the back. But, back up front, the bearing on the main shaft is only sealed in the outer side, after which there is nothing stopping water from going through/around the gears and into the motor. So like… it’s a good servo, but don’t trust the ‘waterproof’ claim. It’s maybe IP64 at best.

Quality

Sorry to say it lasted a dozen outings. My 4w steering ascent 18 original servo is still going strong after more than 50 outings.
