Thanks, that will be useful information for future purchases.

1) AR6300 are 1.5mm spacing JST-ZH

3) AR6400 and HK Super Micro are JST-SH with 1mm spacing

Tim, the new HK 2g 4 Channel DSM2 receiver also has the Molex 1.25mm connectors so these servos will plug straight in (assuming they have been consistent with the wiring polarity!).

Makes a nice lightweight unit at $9.99 for the Rx and $3.57 for servos.

This is pretty rough as I was just using a DVM on the 10Amp range to minimize the insertion loss. DVM's aren't very nice for looking at fluctuating currents.

Best estimates with a Hyperion 240mAh 1S:

FlyDream 1g Rx plus 1 servo

Idle = 16mA
Moving with no load 120-140mA (This will be the peak when it starts, should be less when moving)
Fully stalled 280-300 mA

John

Just one sample, done in a hurry - the usual disclaimers about accuracy.

well that sucks. i was hoping to run these directly off of a AVR, elimnate some weight.
hang on, the 32 TQFP might handle 400mah.... let me look up the data sheet......
nope, 200mah total, sourced and sunk. well, i am going to try it anyways.
he he.

You'll save more weight by drilling holes in the casing

these look really nice. probably going to pick a bunch up with some of those new dsm2 rxs. just got to wait till somebody confirms that they fit together.

I managed to cook one so pulled it apart to have a look at the construction.
(Memo to self - the Red wire connects to the Positive...)

The top gear is removed because (choose one):
1) It gives you a better view
2) It fell on the floor and I couldn't find it

I think the mechanical design is quite good. The properly cut insulator between the Pot and PC board, the clever little tab that acts as a case retainer and a very effective cable anchor and the single long screw which really stiffens up the whole assembly and makes it robust. Gears look very clean and as previously mentioned the servo runs very smoothly and quietly.

Imagine having to assemble these little buggers all day.

Ouch!

I wonder how much the lead and the bottom part of the casing weighs.

With the Blue Arrow servos I always replaced the lead with thin enamelled copper wire and removed the bottom of the casing.

Mega, the lead and lower case together weigh 0.412g. The screw, which you would also leave out if you remove the lower case, is 0.052g.

A significant weight saving. Thanks for weighing it.

Some of the threads on using Walkera servos with an AR6300 (mini-JST sockets), including one on fitting a Walkera with separate components (non-Walkera Rx and Gyro), have mentioned 2 ways to fit a Walkera-type plug into the wider spacing AR6300 socket:
1. Push in with some added force (I have not tried).
2. On the Walker plug, widen the 2 outer pin holes a little (widen on the side away from the other wires). The plug will then fit into an AR6300 socket (but watch the wiring order!: pop out 2 of the plug's wires [and "pins"] and swap).
I have successfully tried this using a Walkera ~3.5g servo and a GWS Pico Rx (mini-JST sockets).

Have a look at this. what do you think Guys !

Is the Kyosho 2.5g servo for the new MINIUM WARBIRD SERIES Spitfire and Zero from the same factory as the HK-282 Ultra-Micro Servo 2.2g . Also is the plug a Molex 1.25 on the kyosho servo.
