I have some Hitec HS-80 servos that flew about fifteen flights in a Caprice
I retired them and am now thinking of using them again. What is the difference between the 80 and today's 81 servos? Are the 80 servos upgradable to 81 specs? Is it worthwhile? TIA

The 81 came out as the 80 went out... they are as near as wotsit the same servo, albeit a slightly different size. Both servos can be upgraded to metal gears and the torque and physical strength of the gears is about the same. Those 80s of yours still have a good few years in them yet. Beware the Hitec 81 btw, the strain relief on the lead isn't great, pulling on the leads puts great strain on one of the wires, if I recall correctly, the neg one.

Ed, I have both and the only difference I can see is the 80's have a white case, and the 81's have a black case. I use the 80's on my zagi
400 and have never had a problem.
Thanks, Doug. There's nothing like asking those with hands-on experience.

Thanks a bunch, my friend. I'll be sure not to tug on the servo leads.

My HS-80 is in a black case!!!

I guess I've had 'em longer than I thought.
