Thomas LVerified owneron Reefs RC Raw 500HD High Torque/Speed Digital Servo (High Voltage)

Got this for my TRX4. Great servo. Very fast and strong even at the stock 6.0v. Running it with stock receiver and hobbywing axe esc. So happy I can turn my wheels when I’m in a jam and get out of them now. The waterproof features sold me as I like to run mine in creeks often.

Quiet , Beautiful, Strong & Fast. These are the reasons I keep going back to this Raw500 servo. Nothing else out there meets all those criteria. I have bought eight of them so far and will continue with them.

What reviewers say

Reviewers broadly praise the Reefs RC Raw 500HD High Voltage servo for strong torque and fast response, with many running it at 6V to 8.4V across crawlers, buggies, short course trucks and other 1/10 platforms. Build quality, finish and quiet operation are frequently mentioned, and several reviewers describe buying multiple units. Reviewers also note the programmer and Reefs software as useful for adjusting centre point and power. The main disagreement concerns water resistance: one reviewer reports a unit failing after running through muddy puddles despite the submersible claim, and another reports failure after a few days of use, which the reseller stated would be covered under warranty. Some reviewers note the lead is short, and one notes the rotor rotates freely when powered off.

  • + Strong torque
  • + Fast response
  • + Quiet operation
  • + Build quality and finish
  • − Submersible claim disputed by a mud failure
  • − Short lead wire
  • − Early failure reported in one unit
