Hitec RCD 33045S HS-45HB AGTT Feather Servo

The HS-45HB is a small feather weight servo. This is an Analog servo that weigh 8 grams, the digital equivalent is the HS-5045HB. This servo has 1.0kg of torque at 4.8v with a .14 second 60 degree transit speed. I like to use this size and class of servo in my small lightweight 3D EPP foam planes. This servo works better than the HK 5g and HK 9g servos you typically see used and it comes with a long arm so you don't have to try and piece together some type of cut wooden extender for long throws on 3D planes. It's faster and more reliable than the HK versions too. To prevent me from cutting my planes apart when those cheaper ones break, I build from the start with this now.These servos come with a plus shaped control horn attached and then a double and single arm servo in the box. The big plus is the very long double arm control horn that's included. They also come with two small flanged mounting screws. One concern I had when I first purchased this servo was how well it would work with an ESC based BEC, since there are no specs listed for 6.0v usages. On my planes, I've had no issues with a standard several ESC's with built in BEC. My favorite is the Mystery or HK Blue 12a esc for these small planes.If you want to save a little, you can by the HS-55 which is only slightly heavier, has plastic gears, is a little slower, but it costs much less.  Hitec 31055S HS-55 Economy Sub Micro Universal Servo I'm sure you've seen the lower cost copies out there. Let me explain why, even though they may be lower in price, it'll be more difficult to use those.1 They have less reliable quality control. Sometimes whole batches of the off brand servos are bad and once you've got it in your plane they can be a real pain to change out.2 These servos are more accurate, center better and are more precise in their movements.3 Do you use and toss your gear or do you re-use it? If you re-use things you really want servos that you know you can get parts for . Hitec sells servo gears, screws, horns etc so you can change broken pieces out as necessary.4 when you need a special longer horn or special piece you know you can get that for your Hitec servos. That is not the case for many of the after-market servos.I have tried the lower cost servos and over time, it has been proven to me time and time again to stick with the name brands to get the support and parts I need. Hitec is amazing for their support; I did have one servo act weird in a rudder for me (it would wag with strong prop wash in big 3D moves. I sent it in to Hitec with a note and they promptly sent me a new one, even though they could not duplicate the issue.5 stars, this is a great servo for a fair price and you'll enjoy these in your planes.

Super small, super light and yet very strong... perfect for glider which is where I’m using 4 of these guys.

On time delivery, well packaged, Hitec makes good products. All good.

Out of four one died the first flight.

Exactly what I was looking for and it works great.

Excellent power and tough gear train.
