    Dual Mode (Hopefully) Tarot Ironman 650 Build

    That's fine - I have stuff that's not strictly necessary. I just like that power distro board since it gives plenty of outputs for various devices.

    F550 battery problems (again) - Help needed please :-)

    There's a MAC version of the Assistant - that's what I use. If you look closely you'll see that the screenshots in the manual are off a MAC! That always makes me laugh to know that DJI uses MACs and that they have so little support for them :-)

    F550 battery problems (again) - Help needed please :-)

    Have a look on page 17 here: http://download.dji-innovations.com/downloads/nazam-v2/en/NAZA-M_Quick_Start_Guide_v1.26_en.pdf. It's a bit involved, but it does work. The main thing I test is how much battery I've used when it goes into auto-land - you want that to be at the 80% point. Do what it...

    F550 battery problems (again) - Help needed please :-)

    The charger is telling you how much energy it put back in the battery, so you are only using about a quarter of that battery before the red light starts flashing. You shouldn't drain a battery past 80%, so working the numbers: You used 1024mAh from a 4250mAh pack. You CAN use 80% of 4250 mAh...

    What's the connector found on a LiPo's balance lead called?

    Those are fantastic! Ordering now - thanks!

    What's the connector found on a LiPo's balance lead called?

    I hate those connectors - I always feel like I'm going to damage it when I pull it out - they're really not well suited for a connection with numerous make/break cycles.

    Wow, that came out small - sorry. Let me try that again:

    Dual Mode (Hopefully) Tarot Ironman 650 Build

    I used this one: http://www.helipal.com/power-line-board-4-8-propellers-drone-type-b.html The holes line right up with the holes in the Tarot center plate. Here's my wiring diagram:

    Dual Mode (Hopefully) Tarot Ironman 650 Build

    Nothing major. It turns out that there's only one orientation of the motor on the mounting plate that allows the motor to sit flush and avoid the fasteners that clamp the plate to the arm. That's a bit of trial and error but once you find the magic orientation it's fine. Then I had to cut down...

    Dual Mode (Hopefully) Tarot Ironman 650 Build

    Yes, I really like the KDE motors, and you just can't beat their support if you ever have a problem. I got the extra center plate directly from Tarot but the shipping was appallingly slow and if you can find it from anywhere else then I would go for it. I terms of the battery, yes: I could have...

    How Do You Avoid Sparking During Battery Connection

    I ended up putting the female black connector on my craft and the male red one - double idiot-proofing myself :-)

    Dual Mode (Hopefully) Tarot Ironman 650 Build

    My local RC store had the longer tubing. It's 10mm OD, 8mm ID as I recall. It works great pushing the camera forward since it keeps it clear of the props and acts as a nice counter-balance for the rear battery. The top battery is right on the CofG so if I want to fly with just one then I can...

    Dual Mode (Hopefully) Tarot Ironman 650 Build

    Sorry for the long gap between updates - been traveling lots so very little time to work on this. I also had a motor mishap - I stripped a thread putting a prop on but KDE were AWESOME - totally covered under warranty - they sent me a brand new motor. Very good service! I will have to post more...

    My First MultiCopter Build

    Go for it - or just post in my build thread. Build treads are great for learning (that's how I did it!) so it's good to keep Q&A there so others can read it too.

    How Do You Avoid Sparking During Battery Connection

    OK, 5.8 ohms between the tip and the main body. If you are seeing either zero or infinity then you will get a spark (zero - resistor has failed to a short, infinity - resistor has failed to an open circuit). You might also be able to see discoloring where the spark has been occurring. If the...

    How Do You Avoid Sparking During Battery Connection

    But that's the exact opposite from the directions that come with the connectors, which is how I'm connecting them (with zero spark). To be honest I'm not sure about this positive first thing - nothing happens in an electrical circuit until there is a closed path for electron flow, and the...

    My First MultiCopter Build

    You could run that at 6S and easily carry a couple of 5000mAh batteries. You are close to my config with that - have a look here: http://www.multirotorforums.com/showthread.php?22168-Dual-Mode-(Hopefully)-Tarot-Ironman-650-Build I'm getting just over 20mins on 2x 5200mAh 6S with 14" props, and...

    How Do You Avoid Sparking During Battery Connection

    I'm not really sure. What's your setup? In terms of current draw at startup, that should simply depend on voltage and the components you're powering up. I'm running a quad on 6S so you have 50% more ESCs than me - maybe that's a factor? Perhaps someone with more props than me can comment.

    How Do You Avoid Sparking During Battery Connection

    LOVE the AS150/XT150 setup - really nice connectors. Absolutely zero spark, very firm connection and easy to disconnect. Perfect! I made up a Y harness so I now connect my two batteries in parallel via XT90s which run into the AS/XT150s. That way I just have a single connection to make for power...
