I've got some HS-65MGs I used in a glider wing recently. They're decent servos. Only .44 oz in weight. The box says their output torque is 24.99oz-in @ 4.8V (30.55oz-in @ 6V)


The other day I was looking at a buddies new 65' wingspan ARF and he had a pair of HS-65mgs in the tail driving split elevators. They looked too light for the model. It'll probably weight about 7-8 pounds ready to fly. He's been doing this stuff for many years. Before saying anything, I picked up one of the boxes and checked to see if I was remembering the numbers correctly. I was surprised.

The box said HS-65MG Mighty Feather for sure.

The specs said the torque was way more than 24.99 and 30.55. A LOT MORE.

I came home planning to order some more of them suckers and jumped on Tower's website. They show those babies still being 24.99/30.55

What is the deal here? Are there more powerful ones or did I read the box wrong? I've emailed him to get him to check the boxes, but haven't heard back.

There is only one version.

OK, it looks like a simple mistake.

The Output Torque apparently has invalid oz-in numbers on some of the boxes. The kg-cm values are the same on old and new boxes, but the oz-in numbers on some boxes are simply incredible.

Hopefully not too many modelers will purchase those HS-65MG Mighty Feather servos that say on the box they will produce 69.43oz-in @ 4.8V and 83.32oz-in at 6V expecting those tiny little things to put out that kind of power.

Good thing is the modelers who work in metric won't have a problem at all.
