    The more I have to deal with PID the more I like KK boards!

    What was I thinking when I bought a Quadrino board for one of my little quads that needs a USB connection to the board and a Java based GUI to set the PIDs to get the D**m thing flying??? At least with an MK the board it pretty much works out of the box with the factory default settings, heck...

    Whats this?

    What you can charge and get away with really depends on your target market and the expectations you set with your customers. The average hobbyist would like to think they get support from the vendors they buy from but how many times are you able to send an email or make a phone call and get a...

    Mikrokopter Precision I2C to PWM converter

    After an interesting day of attempting to dial in the GPS settings I think I can shed some light on the problem you're having. First, the I2C bus Mk uses to talk to the standard BL's is faster than the PWM communication you get with the converter, what that means is the reaction time of the...

    X8 coversion to MK - shopping list suggestions

    No longer available as in no one that is a dealer has any in stock and they're not going to make anymore. The replacement motors are now being branded as Cobra and they do not yet have a equivalent size/kv for sale yet and may not ever have a direct replacement. I'd like to have at least one...

    Tau Labs Whats all the fuss about CopterControl

    It's a dessert topping! It's a floor wax!... ;) (bonus points to the first person that knows where that came from) This sounds like a great all around controller, once the software is stable and a version or two has proven itself I may take the leap myself. After all the firmware issues...

    Mikrokopter Precision I2C to PWM converter

    Coming along nicely After work today I did more tweaking of the X8 and the I2C converter. Just to make sure the board has the most recent version of firmware I flashed it using the file available on the website. After that I put a bind plug on and let it do the ESC calibration routine again...

    Motor for 1.5 kgs Quad

    I'll second the Flycam motors, I have 8 of them on my X8 which weighs in at roughly 3.2 kgs RTF or a bit over 7 lbs in nonmetric measure. Ken

    Shawn, good to see you made it over here! Good luck in the drawing, now lets get you setup with an Mk controller. When you have a chance please post some of the pictures and details of the work you've done and are doing with multicopters, I think the people here will find it fascinating. Ken

    Wanted Wanted - Droidworx camera mount

    Its an MK Hisight and the thing is there's no good way to securely mount a GoPro to a Hisight mount, the frame of the mount isn't tall enough to use the GoPro case with any kind of foot or tripod mount. What you can do is use a piece of soft foam under the GoPro and velcro strap around GoPro and...

    Mikrokopter Precision I2C to PWM converter

    Correct, there's nothing that needs to be isolated without the BL's. Ken

    Any multiwii gurus among us?

    I'm using ESC's that are supposed to be Turnigy compatible/clones, i.e. the same programming card works for both. Apparently the programming mode is compatible but not the speed of the ESC...??? I have a set of turnigys I could try but I hate to use all my spares just to see if it will fix...

    Mikrokopter Precision I2C to PWM converter

    I can, just not sure when at this point, rainy and windy today and possibly for the next few as well. I had it flying on altitude hold last evening and it held nicely, just need to get the GPS installed to see how well it holds position at the same time. See my X8 build thread for specifics of...

    X8 build

    Both actually, I did a lot of testing on my X8 in collaboration with another X8 Hoverfly pilot from Texas, and from much reading about coax setups I see most people running the lower motors anywhere from 7 to 12 percent faster. Other strategies are to use a higher pitch prop on the lower motor...

    Mikrokopter Precision I2C to PWM converter

    I did the calibration when I installed the converter, read through all of the relevant discussions over on RCG. The only time I see the motor stop behavior is if the X8 lands off level, haven't tried it yet but I believe setting the min gas setting a little higher will fix the problem. Otherwise...

    Well then, you may want to look into these, they've been reported to work fine with the Precsion board too! http://www.hobbypartz.com/volcano-40a-brushless-electric-motor-speed-controller-esc.html I've done a fair amount of business with Hobbypartz lately and they've been great. Located in...

    Mikrokopter Precision I2C to PWM converter

    No brakes on the Turnigy Plush ESC that I'm aware of, I think its probably just a quirk of how the converter interacts with the MK. If you land a bit off level with the thottle at minimum the F/C may send a signal that's below the start point of the esc to try and get the frame back to level by...

    Mikrokopter Precision I2C to PWM converter

    Do you like Mk flight controllers but don't like being locked into using I2C controllers with it? There's a great way to fix that problem for not a lot of $, http://abusemark.com/store/index.php?main_page=product_info&cPath=1&products_id=3 After building my X8 project using standard Turnigy...
