Servo replacement

[360modena]

Can anyone please suggest a digital servo replacement for the HiTech HS81 analog servo. I used these for throttle and the 3rd channel mixture control. Thanks.

Check out Promodeler servos. They have many sizes on their website. Richard

This can be tricky.. Its important to note most of those tiny servos are designed for electric applications and dont support rubber isolation mounting. My choice is the Futaba S3172SV

None the less just an option.

I have been using the HiTech HS-5087's in my nitro boats for mixture and throttle. Great little servo's and no issues.

Thanks. I will check them out. Years ago I always used the HiTech HS81 for throttle and mixture and never had problems

I am in love with Savox. I use the full size aluminum case on big boats. The blue one on medium and the small 2 hole mount on 26" or less RTR upgrades and throttle. Most are not in a radio box. Never a problem, waterproof, tight, and up to 444 oz torque on the full size one. I also use them in airplanes.

Thanks for the info Brett. Just coming back into the hobby after 10 years away there seems to a lot to catch up on with servos and transmitters. I have 8 Futaba 1024 PCM transmitters, 2 new in the box and never opened that seem to be VERY outdated. I am going to go with the Futaba transmitters but I am still contemplating which servos to use. Thanks again for the input.
