Great servo Review by William
Got 5 of these servos, great servo, awesome price, had like 10 flights with them and no complaints at all, installed on my 50cc 78’’ 540T areobeez, love them. (Posted on 7/28/2018)
Solid servos that so far seem to be doing well Review by Michael
I have purchased about 23 of these and the 13kg version and am running them in a 35cc powered ultra sport, a SIg Four Star 60, Pheonix Edge 540, and a 89" Dynaflight Super Decathlon and they have been rock solid and have worked flawlessly. Centering is pretty good but not as good as some other high end servos.....which I would not expect at this price point. For the money I do not think you can beat this performance. I will happily use these servos in these types of aircraft and have no complaints at all.

I am building a 50cc Edge and will be giving the B3 or B4 a chance in that plane. (Posted on 7/13/2018)
Using these in 100N sport jets Review by Stanley
I had been using the LF-13 servos in a Hangar 9 Valiant for over 2 1/2 years without any issues at all, and flawless performance, so when it came time to start into jets I went with the LF-20. It has been almost a years with the LF-20 servos in a Boomerang Sprint with a JetCat P-120 without issue. I have 6 LF-20's on the surfaces and an LF-13 on the nose gear steering. I have had zero problems with these servos. Don't let the price fool you, these are quality servos. They run the Futaba spline so finding aluminum arms is simple. If you need servos in the 250 oz-in range these are the way to go. I have 7 LF-20 and an LF-13 ready for my T-One Jet from Pacific RC Jets ready to go as soon as it arrives I am so confident with them. (Posted on 2/7/2017)
Great performing, well centering, a great value! Review by John
Have ordered these servos twice. I love the 1501's and these perform just a good, are quiet and very powerful. I am running these LF-20's on 2 cell LIFE batteries without a regulator. I had tried another brand servos in my latest plane during set-up and found that they would not match performance with each other; not so with the LF-20's, they match flawlessly and most importantly, I TRUST the Power HD servos. Super value for the money spent; I will buy more! I would even trust these in a helicopter.
