Default Noob question

well i have been flying for about 2 months now. froward flight is manageable for me and landings have gotten better.

I was flying recently and at the end of my 4 min flight time on my t-rex 450 ( a flight consists of a few 4-5 pattern passes and a landing. I just repeat that for practice )
after a landing i took off and i noticed it shake quite violently. tried to land but it wann't pretty.

when i went over to it i noticed a hum coming from the elevator servo . it appeared to be stuck downward. if i un sitck it it will function normaly for a bit and then get stuck..

Is this a bad servo or striped? wondering how i should look into replaceing it ... new gears?

By the way it is the karbonite gears not the metal .hitec 65


thanks for your help

Sounds like stripped gears. I'd advise getting metal replacements.

Experience is something you gain only after you need it.
I wouldn't mind social media so much if it didn't involve people.

Can i just get the metal gear set for the MG or do i have to get a new servo? I was hearing that they were the same but just the karbonite vs metal gears.

The only difference between the MG and HB servos is the gear material. So, you'll be just fine putting metal gears in your HB servos.

A buddy of mine tried to put a metal gear set in his stripped HB servo.......he had major binding with the metal gears in there and couldn't remedy it. Then I read that the gear sets weren't compatible. After THAT, I read that something special had to be done during swaping of gears to make it work properly.

I didn't bookmark any of those things I read but I'll try to dig something up.
