The Inaugral Multirotor “hover-in” in New Zealand.
20th March 2011 – Tokoroa Air Field, hosted by the SWMAC (South Waikato Model Aero Club) http://www.aardvark.co.nz/swmac/ and Bruce Simpson of RC Model Reviews Fame http://www.rcmodelreviews.com/ knowen as Xjet and RCMR on YouTube.
A total of 6 pilots descended on the field on Sunday, Wayne and Stu both from Tauranga, Keith from Auckland, Pete from Hamilton, Ivan from Cambridge, Me (Mathew) from Hawera, and not flying (yet – its in the-build) Neil from Tauranga as well. Tauranga seems to be the multirotor epi-center in New Zealand ! (as waynes wife also has a quad)
Great Day, not to much damage done (apart from Keith bending his nice Jakub frame, dihedral always helps 🙂 and Ivan’s reciever coming loose and thumping the controller) and lots of Tuning, as two quads were tuned, plus we did a Minsoo Kim blue board install on Two Tricopters at the field and had them both flying in 5 minutes !
Wayne showed us some “sport flying” and Pete did a whole lot of Go=Pro video shooting ( I think he flew a total of 8 batteries for the day)
Out of the 7 quads/tri’s , at the end of the day, 1 had a FY90Q controller, and the other 6 had the Minsoo Kim Blue Board (KKuk derivative) all running xx_multicopter v1.5 software.
Photos from the Day – thanks Pete
We have another fly-in next weekend (26th/27th March 2011) at the Hawera-MAC http://haweramac.wordpress.com/ and we should get 5 pilots to that event (Wayne and Julie from Tauranga, Brendon and Mathew from Hawera and Brett from New Plymouth)
Want to know what settings to use for your ESC’s on your multirotor multicopter ?
A picture speaks a thousand words…… well maybe 80 in this case 🙂
Settings for ESC's on multirotors
Set the the brake on or off depending on your preference, its not critical
Set the Battery Type to “Nimh/NIcad”
Set the Cut off to “soft”
Set the cut off voltage to “low”
Start Mode to “normal”
Timing to “Middle”
Music on or off, thats a personal choice 🙂
Governor to “off”
Thats about it.
“Mat” Earnt its supper tonite.
added an icecream container and swaped to the 4S 2650 lipo
AUW 1020 grams
then loaded 1455 grams into the container as a load (1.43 times its weight)
Hovered well 🙂 had to bump the throttle maximum (for headroom) to 75% as needs about 60-65% to hover
would have been pulling 28 odd amps and hover time of 4.5 minutes.
You could tell it had more mass, carefull not to build up too much speed, but very controlable, and more stable.
Progress on “Mat”
Yaw set to 125% throw no expo, Roll and Pitch to 100% throw and 20% expo, biggest change was going to “heli” mode on the 9X and programing a throttle curve, from 25% to 100% of the throttle stick, the throttle command to the esc’s is 40% to 60% – more than enough, really helps height control when hovering.
Stage 2, now you will see the reason for mounting the controller UNDER the frame , is so i can add a large platform to the top
140mm wide, 270mm long, this prototype is made out corroflute, the finishe3d version will be fibreglass or polycarbonate.
it allows more batteries to be carried, and when a camera is hung on the front, the batteries can be moved aft to counter balance, gives the camera an unobstructed view, while being nice and compact, and not hanging below the frame.
