Molex Picoblade? Fancy name, thanks, I didn't know what they were called!

I used the HK 2.6g servos, with the tiny little connectors. As I said, don't know the name of them, but once I pulled them apart, I saw the sockets are actually quite large.

Edit: So i found out what they are... Do you have a buddy code for your order?? I'd love one.
Check out this site:

Makes it a lot easier! I'll be throwing mine up as soon as it allows me to.

technically speaking- you use the "sweep area of the fan"
but the inside dia of the fan shroud is also commonly used.
but this in not rocket science..... its only jet science.
so use what you feel is best.

FYI 35mm-14mm Calc

and the largest part of motor hub assembly

To use the AR6300, swap the red and brown wires on the servo plugs by carefully
prying up the plastic fingers on the connector while gently pulling on the wire,
then reinsert the brown wire in the middle and the red wire on the end.
Trim off the little bump of plastic on the connector housing and press them into the
AR6300. They are tight, but they fit. I cut a little trough on the right side of the fuse
so the RX fits down flush with the top of the canopy opening, with the connectors
toward the front. Couple drops of hot glue keep it away from the elevator servo arm.
Very clean, and allows room for the battery after trimming the foam bulkhead ahead of
the servo.
Maiden today.
Is yours a HK Saber or a Banana Saber. I ask because my Red Mig from Banana will be here on Monday. I've been reading, trying to figure out what RX to use with my JR x9503. If I can just get the pins out of the keepers and plug each individual into an AR6300 that would be the berries!!!

I like the RED Mig! HK won't stock it I imagine. And shipping from Banana to Australia is "forget it" expensive (as much as the model!).
HobbyKing don't stock alternative color schemes of the 50mm series so probably won't do so with the 35mm ones.

My F-86 thrust tube is ready to install. Once it's in and confirmed to be good I'll see if I can make a template for others to use.

The hell with the red MiG... I mean come on, I get it; they're Communist. Big deal. Maybe its just me but I prefer the at least semi-realistic colour schemes. Mind you I can definitely see why some like the red scheme, it does look sharp.

Anywho my Rhino 3-cell 360's showed up the other week as well as a replacement servo for the one that jammed in flight. I reckon its rebuild and refly time!

Cheers - boingk

I had the HK Mig. I expect the servo plugs will be the wrong micro connectors for the AR6300. So I used this3" JST Extension Ultra Lightweight [SPMEXJST3UL]

Carefully crush and cut away the female end of the extension to free the pins. Then you simply plug the pins into the male end of the servo and plug the extensions correct connector into the AR6300. Just reverse the positive and negative wires from the extension into the servo. Wrap the connector/pins with some blenderm or shrink wrap to hold the pins in and your ready to go.

e.g.

With the rotor diameter of 35mm and motor bell of 14mm diameter:
35mm˛ - 14mm˛ = 1029mm

√1029mm x .85 = 27.2mm diameter

.
Aren't you forgetting Pi?
Area of a circle, based on radius: Pi · r˛

When scaling an area I would:
factor˛ · area = scaled area

Then, this scaled area to a radius:
√(area / pi)

Then, the calculated radius time two and you've got yourself a new diameter..

I come to 29.57 mm diameter this way for 85% FSA.

Excuse me, I might've forgotten about squaring the scale factor in my last calculation
I come to 27.27mm diameter *walks away in shame*

boingk,
1.) Get your panties untwisted

2.) Watch this historical footage from the Soviet Aerobatic team (with their RED Mig 15s.
Soviet MiG-15 Aerobatic Teams - part1 (9 min 55 sec)


3.) Embrace Communism, comrade!

RNAF -

Meanwhile - the front mounting plate of the stock motor is 10.78mm.... Yup! Just a whisker too big to slide into a GWS 30mm shroud. Mounting holes are too close together to use in an AEO 30mm shroud. So, in the lathe it went and I removed the 0.78mm extra so it fits into a GWS shroud. Ooops!... the motors neck is not long enough to reach the front motor mount of the shroud. It's about 2mm short. Out with a 12mm drill bit and take out some of the back of the stator vanes and motor mount.

Why? Odysis ran his on 4S and even though he used saggy lipo's it handled it without incident. Since this is the first 14mm outrunner I have gotten my hands on (with such a low kV), I just have to try it in a 30mm fan unit. On 4S for starters no less.

My thrust tube weights 2 grams! Two whole stinking grams! It's too heavy!
2 grams that far back is murder for the CoG and it's all out now.
I need some really light weight plastic .... or maybe paper is lighter? How much does paper weigh?
*grumbles*

What about tracing paper or news print paper? Should be pretty light.

I've even thought of using the protective clear layer of Monokote. I have some so it'll be pretty cheap.
