SpektrumA6380 High Torque High Speed HV Standard RC Aircraft Servo: SPMSA6380, Black

For $30 this servo works great. I've bought 6 and have them in two model airplanes. Digital, HV, good output torque, occasional buzzing but not much. They are fast enough. They come with a good assortment of servo arms/screws/grommets.

Excellent, as described.

Worked great on RC plane

I am using these servos on a 50cc Extra 450 and hey work well.

This is a product that always exceed my spectations. Well built and reliable.

I fly all kinds of models, from small to giant scale. These have been my go to servos for about a year now. I run a 7.4 2S lipo battery to power my receiver which makes the servos pretty snappy. I've purchased about 40 of these with a failure of 3, so if my math is correct, that is about 1.3% failure rate. Not bad at all. Performance wise, these servos do well, they have no problem moving the control surfaces on my 1/5th scale P-51.

Put in my comp arf yak and love the accuracy and slow start really is a nice feature to save on wear.

These are pretty good value for a high voltage servo. Been using them in planes from .60 to 1.20 without any issues. Out of 10 purchased 1 was defective out the box which I was able to remedy directly with spektrum for a replacement unit.
