Cool post....thanks for sharing

Immersion stuff is great....but it's with strawberries. In the right season you get some....but most of the time not. Had to wait for almost 3 month to get my habds on a 600 Mw Tx. One downside is the limitations (8 Channels) within the 5.8 GhZ range. In 5.8 GhZ you have 4 bands with 8 channels...

Thanks a lot.....:tennis:

Brazil....that's where you have been.....I already thought you went to retirement because of filthy rich-ness. :tennis: Cristiani is absolutely right.....dangling wires don't look pro.....in my case at least the copter looks pro, so I got moore room to be messy. The Greyphon board is not...

Cool....thanks for the info....wil try it Chris

Enjoy your stay........ Weather should be great :tennis: Chris

I tried a standard SMA Cloverleaf on the DJI-Data Link....didn't mach. Have to try something else once I am home.... Chris

I have set up my YS-X6 with WiFi Router / WiFi Unit / Data Link / Samsung Galaxy Note II...and that part is working. I want to use S-Bus, but I can't find the right place in the GCS software to set it to S-Bus.....can't imagine that it sets itself automatically to S-Bus only by plugging the...

OK....then it's clear. Didn't want to sound like a teacher, I was just worried about your beautiful Droidworx......:tennis: I wish you a lot of crash-free flights.... Chris

One question: Did you replace the re-inforced arms yourself .... ??? When I replaced my arm and did the soldering, I realized that the metal spots where the wires gets soldered on is thin like a hair....If soldered to hot, it could be that the soldering joint becomes loose together with that...

Cool.....seems clear now and sorted out. :tennis: Just one question: By looking at your photo, it looks like the IMU is mounted on top of the Flight controller box....not so good. It should be away from other electonics as far as possible. Also make sure you have a good vibration dampening...

That's good. X-axis is forwards (+ value) or backwards (- value) ....looking from above at the copter Y-axis is right (+ value) or left (- value) Z-axis is down (+ value) or up (- value) ....looking from the side at the copter. Let's say your IMU is mounted on the center plate, but 5 cm to...

Glad it helped....but you have your Center of Gravity 8 cm above the center of the frame....? (reffering to your IMU values on the Z-axis) PS: Don't forget to find your Center of Gravity only if everything (LiPo's, Gimbal....) is already mounted to your copter !!!! Chris

Build-tread updated: http://www.multirotorforums.com/showthread.php?12478-Build-thread-KRATOS-from-Flexacopter-Ultimate-Octo-Copter BTW: Any more info on those 35V/45A ESC's you mentioned in your previous post....???? ....and what's your conclusion on the new props so far....? Chris

Now it's time to solder the motor-wires from the frame to the ESC's : After is't finished, it looks like that: Once everything soldered, the next step was to heat-shrink the ESC's again....but don't forget to put the extension cable from this ESC's (programming port) and route them...

Centerplates (Main Frame), Power Distribution and ESC's The great thing about the Kratos is the fact that you don't really need a build manual. Everything comes assembled, you just have to take a few screws out, do your work and put the screws back. How many times did I build something, just...

First step should be to find your real Center of Gravity.....this will be the reference point for your measurements of IMU and GPS. It should be in the center of your copter, but many times it is not the case. Don't measure from your IMU to GPS.....both measurements have to be taken from the...

True....but have you ever tried to get 3-axis with these boards straight ??? Even the real hardcore-guys are struggling with that......definitely not the right stuff for us Chris

There are a few apps for iPhone and/or Android smartphones to check how many satellites are avalible, signal strenght and so on. Pretty helpful to get an overall indication of GPS coverage at your location.... I am using this one...
