80 mah battery won't last long with the Rx & 2 servos drawing power.
It'll depend on how stiff/ free your control surfaces are (if the servo needs to work hard it'll draw more power) & how much you are working the sticks.
Assuming everything is perfect, I'd hazard a guess at 15-20 minutes. If stiff tail surfaces & lots of stick movement, perhaps 5 minutes.
I would fly for a timed 2 minutes & then check how much power remaining to determine a safe flying time.
Do these have a full mechanical range of 180°*. The HK-5320 ones only have a mechanical range of about 100°* (caused by the potentiometer, not only the mechanical stop).
On a classic RC system you mostly use only about 90°*, but in this Arduino project 180°* would be welcome: ***********instructables****/id/Zappelin/
In short, I'm looking for the lightest 180°* servo.
Given the weight of some of the new CCTV cameras out there (1-4g) it makes sense to me to take two of these and glue them together then mounting a camera (if it crashes and breaks, who cares, replace them)
Plastic and 0.04sec 60deg *4.2v seems ideal!!
Can I replace the servo lead with a regular servo connector? I'm happy to test if they are OK at 5V and since they arent critical to the safe flight I dont mind if they burn out on occasion!
Any similar experiences or thoughts?
yah the casing is almost identical to the other servo with less power so the bulge is most probably housing the bigger motor but I would like to know the dimensions of said bulge. I doesn't seem to do the whole thickness of the servo.. Anyway I have another week to wait for the delivery and I'll see then . The dimensions would help with my CAD drawing right now..
No, these servos are only rated for 4.2 volts. I accidentally used this servo with a 5 cell nihm rx pack just to test a 415rx while binding and it got hot enough to warp the plastic case! So remember nothing over 4.2 volts.
Please do NOT use this Servo with 2S! (like me)
This part is designed up to max. 4.2V 1S and not max 8.4V 2S.
You will blow up this Servo with 2S
Remember that a full charged 1S LiPo has 4.2V! and not 3.6V
2 cells are fine, put a diode 1n400x in the red lead with the stripe towards the rx.. this will drop the voltage so all is safe... Ive got 3 of these servos working nicely with a 6A turnegy plush esc, orange micro rx...
Can i ask a question? Today i get these servos and in the manual (in german language) its said, that i can use only batery with max 40C rating. Is there any problem when i will use bateries with C rate above 40? because i already buy 2 pack of bateries with 90C... Thanks a lot.
My axe 100 cp also use this servo, the nine eagles 125 also use this servo.
I used this servo on my Blade 130x. So far the results seem very promising http://youtu.be/krH-Hs05KVA
Hopefully HK will come up with similar servo with a little more torque, speckturm compatible plugs and a mount for the 130x. 130x is a VERY popular heli.

Great servo, really miniature and the torque is ok for little planes. I use them for smal depron gliders togther with the FrSky VD5M receiver. RC equipmet incl. battery about 10g! The connectors fit well! Just ordered some more...
