Absolutely! They are FAR superior to Spektrum linears, and as they keep adding weight to the linears the 5320's are alot lighter to boot. ( out of over 30 of them they weighed in at 1.82-1.87 grams right out of the package ) I use these for all my micros, including every new HH micro I buy, they get whacked as soon as they come out of the box and get these installed in place of the linears. Cant go wrong man, try some out.

i use them cuz of the lack of noise. i hate the linear noise. and the spektrum started off at, 1.5 then 1.7 now 1.9. stock new twin screw hk5320 is 1.88g if you are psyco you can get them down to 1g.

menudo: id love to see some pics!

I use and have used ar6300's, 6400's, and hk415's. the 1.25mm molex connector that comes on the 5320s is plug and play with the 415 rx's, any other rx's you need to change connectors and make sure you have the pin arrangement correct. I also recomend running them on 4.2-4.3 volts over 5v. They do work at 5v and I personally havent had any problems at that voltage, but others have had them get hot, so as a precaution I slip a diode inbetween my esc and rx to drop the voltage around .7 volts.

Neither of mine center and one rocks/shake if you release the stick. Is this normal? I only have two so my opinion really doesn't weigh much.

Thank you for all of your feed back, I think that I will get one of these servos and put it on the ailerons of my UM Osiris V2

All my servos rock/shake when I release the stick because it the bounces between the spring things that keep the stick in the center, not sure if this is what you were talking about.

Believe it or not, I just used these on a Gravityhobby Zero with a ZX technology 72MHz rx. and a 10 gram motor. I yanked the linear servos on the ailerons (one on each aileron) and replaced with the 5320 for more throw. This plane is very fast. I just got more of the servos for my micros. I will use up my stock of linears but I anticipate that new orders will be for the 5320's.

Oh, I did put a diode in the supply circuit to cut the 5 volt supply down to 4.3 just to be safe.

The servo its self continues to jitter until I move the stick away from then smoothly back to center.

that is one anxious servo... a jumpstyle servo!


BIM - I have 2 dozen and not a one behaves like that. how about if you switch ports does the other act the same way?

Pull the bottom of the servo case off and try a squirt of freon on the exposed internals to blow out any debris, then put it back together and see if your servo is still twitching...
