So please, can anyone tell me where to put each of the three cables?

Thanks a lot!!

man, it was written here at least 5 times, search the forum please next time. I will post it for the last time now: yellow cable - gyro gain settings (plug into receiver or servo tester), "female" connector - here you will plug the servo cable, male connector - plug it into gimbal output on your FC (pitch/roll channel depending on location of gyro)

those retracts look easy enough to make. just a single pivot point and a servo

I'll have to experiment more as i probably added too much now and my roll servo is twitching. I found a good subject to train on. Here's a few short clips (as the setup was worse than my previous video, conditions: light wind), I'm itching to film something rather fiddle with settings forever...

Stan, really appreciated!!
And I HAVE SEARCHED, but never found this explicit description.
This makes my day...

Sure, you have to read a few consecutive posts to put it all together
This is my old post from this thread (no flame please :

"The gyroscope doesn't work if you don't connect all wires. One goes into servo, the other configures gyro sensitivity and mode (normal/heading hold) and the third wire defines the gyro offset + provides power to the gyro and servo.
You must connect servo (that is clear , you have to provide sensitivity signal (otherwise the gyro is disabled) and you must power it and set the offset (it is helicopter gyroscope originally used to compensate tail drift - so what you actually do is that you define the "tail offset" which is in our case the angle of your camera)."

I love that retractable gear. I was working on a single servo system with cables but this seems to be simpler, maybe a few grams heavier. Will you offer those as an upgrade?

I was also thinking about lengthening the beam for smoother slower reaction. I guess this only works for calm days, no wind gusts?

Great work again but I think you are way ahead of the times with Stereo..

I think this description and some very good hints of Jelico around page 40 to 50 in this thread are the key to a well performing ecilop system.

The manual lacks in this very important point, while everything else about the ecilop is unrivaled well constructed, fabricated and prepared!

85mph wind in NYC, might not fly today - so have nothing else to do than digging through old footage. I remembered using the same subject a few months ago:

They cut down the tree (0 min 46 sec)

Hope it isn't too drastic out there

- so have nothing else to do than digging through old footage. I remembered using the same subject a few months ago:

Yeah, did that tree stump get blown across the Atlantic?! Your circling skills are way better than mine, I need to practice that, so it happens without thinking. It's a great training subject. I'll persevere, watch this space....

Retractable chassis look great, but I am not going to sell them. First of all they may cause some vibration. Secondly – they are easy breakable during hard landing. If the pilot already able to hang in place, it’s better to avoid chassis.

My experiments with the long balance beam are to be continued.

After buying this kit and reading up all the pages, i still didn't get to see how to wire up those gyros, servos to the RX.

Can any kind soul provide a proper connection diagram or schematics ?

there is picture in the manual and a description only a page ago

From Stanleyy: yellow cable - gyro gain settings (plug into receiver or servo tester), "female" connector - here you will plug the servo cable, male connector - plug it into gimbal output on your FC

I sympathise as there's info overload when starting all this. Previous posts seemed to have vital missing info such as plug colour.

Servo plug is the easy part as it plugs into the only female from the gyros

Plug both Yellow cables into servo a tester which stays on the Ecilop permanently and allows you to twiddle the knob for adjusting out the swinging movement of the camera gimbal. Or plug both yellow plugs via a Y-cable into Gear channel (adjust gain on TX). Use Aux3 channel (Spektrum AR8000 RX) to adjust camera pitch angle in both cases. In all cases make sure the plug is the correct way up so it's not in the + or - slots

If you have the Naza FC then Roll gyro black male plug into F1, Pitch gyro black male plug into F2

If you go to HK 401B product and then scroll down and select "Files" tab you can find there user manual of the gyro and everything is explained there.

... or PDF manual directly https://www.hobbyking.com/hobbyking/s...3X179727X8.pdf

I saw the picture of connection in another thread so here it is, it shows pretty well how to connect the system.
