Success! Finally completed the maiden flight. I only flew long enough to try the different flight modes. The thing fly's great. It has the responsive flight characteristics of the Open Pilot CC, and better altitude and position and hold than the DJI. And its just smooth.

Why does it take so much more throttle to takeoff in manual than in Attitude?

I'm running Avroto 2814-11 770KV motors, 12x4.5 props, 40A ESC's and the current AUW is approximately six pounds without camera and gimbal. It took about 60% throttle to take off in manual mode.

Happy, happy, happy.

I don't want to here that, I've heard how SimonK ESC's are supposed to fly smoother...

Thanks for the info.

in some way they do, I do not hate SimonK but I swear that a few of my rigs that are on normal T-Motor programmed ESC’s fly soooo smooth.
The SimonK ones do just fine though... no worries!

Manual mode is an actual throttle, Atti and GPS are not. In Atti and GPS 50% throttle is “hover” and dropping/raising the throttle just changes the height, the FC still controls the motor speed. So depending on a throttle curve or ESC response you may see a higher or even a lower throttle position in manual mode.

That's what I though, which means I'm probably underpowered. For those Avroto's the largest prop is supposed to be 12x3.8, with the 12x4.5 I flew about three minutes using 40% of a 5800mah 4S battery and everything was cold to the touch. Do you think 14x4.5 would be too much?

Yea I think a 14” would kill your efficiency. 12/38 should be great with that motor.

i was getting 10+ minutes on a 6.5 - 7lb machine with (1) 6000 mah 4S pack on the avrotos 770kv

SLEPYC i just got 12/38 prop will the motor that came with the 650 pro p7001 be ok to use with those props will i get better time?

Optimal propping of motors is simple if you have a set of curves for that motor. Look in the data for the highest Grams per Watt figure you can find. This is the measure of the conversion of electrical energy, (measured in Watts, a unit of power) to lift, (measured in Grams). Whatever prop achieves the best figure, is where you start. You can generally go one step up, or down, from this size and see what happens, seldom two steps. Typical figures for current technology are 7-8-9 Grams per Watt. (An interesting aside: Tiger claims their large-scale "U8" motors can yield as high as 16 Grams/Watt under ideal conditions. That's what 32 poles and a 50mm frame diameter can buy you. These things turn 24" props and are wound at 100kV for 44.4V, 12 cell, packs. Yeowwch.)

That’s an 800kv motor. Most of the motors I have experienced in that size like a 10” - 11” prop. I’d suggest trying them out, fly for a few min and see if your motors get hot or your ESC’s get hot.
If not then see how your flight times do.

All teh calculations are great, but sometimes real world power and times will be surprising.

My T-motor 740Kv motors are supossed to like 10” props, but with a lower weight machine like a Disco, I have them on a heavier machine and they LOVE 12/38’s,
SO.... it cna be trial and error as long as you are right within a size or 2 of what is recommended.

Welcome to MultiRotorForums.com!!
on my coaxials with the Tiger 2814's (770 kv) i was running 12x5 on top and 12x6 or 12x7 on the bottom. never tried 14's except for a few times and it didn't seem like such a great idea when they were running.

I've got the same Avroto 2814 770kv motors on my quad and I fly it with 12x3.8 APC props. They seem to perform best with this size. Although I've only tried smaller sizes, nothing larger.

With a 4500mah 4s pack, AUW is 2857g or 6.3lbs. I usually only fly for 6 minutes but on manual mode 50% is hovering for me so it seems like your's should be similar.

My first SuperX video. Sorry but I start out slow and boring.

I mounted a Hero3 directly to the frame to test stability and vibration. There's a tiny shutter so there's probably one prop that needs a little more balancing but overall considering this was my second flight and first video I couldn't be happier. The Hero3 was set to 2.7K@30fps, In After Effects I placed the footage into a 1080P composite, framed it up to lose the motors and rendered. I used Cinema Tools to convert from 30fps to 23.976 so the footage is about 20% slower and left everything else the way it was shot.

For the flight I took off in Attitude mode to a hover of about 10 feet, switched to GPS and then the only control I used was yaw. You can see the flag moving slightly, there wasn't much wind, what wind there was the SuperX didn't seem to care. Most of the movement was from my fat thumb on the yaw. Its really nice to move the Yaw and not lose any altitude.

You can mitgate the yaw wiggle by turning the yaw gain down to 0.9 or 0.8 and adding *just a dash* of expo on the TX rudder channel.

I just looove my Y6 just with SuperX, It will be my weapon when shooting with Hero3. But it is just most fun flying thing I´ve had!

View attachment 15485


We gonna make some presentation video Our all Y6, X8, Hexa With brushless gimbals and SuperX later from Dark FInland:) . Here just for see how mine Y6 flies in attimode with led´s:

I have here Flyduino HL XL frame and Hobbyking electric´s.

Just a question about esc´s?
I Learned flashing my esc´s and Hobbyking Blueseries 40A works just great with SimonK here .
I am anyway new in flashing.
So Do anyone have experience or is it possible to flash esc´s to Ultra PWM or what it was :/ ? Do I benefit flashing esc´s to something else than SimonK with SuperX and is it possible?
Thanks if someone have link some tutorial-videos?If possible. Now X8 night :)! Br, karri3nen

My home built quad has Axi 2814 and I am flying it with 5s 5300mah and getting a solid 12 minutes with room to spare. I tried 4s but got about 1-2 minutes less. I am using 11x5 graupners at the moment. This is with FPV gear and gopro with brushless gimbal.

Is there as much a difference going from 4S to 5S as there was from 3S to 4S? I remember a significant increase in lift without any real bad side effects. Are the AXI 2814's rated the same as the Avroto 2814's at 4S?

What's your AUW on this unit.

I'm building a new x8 with 400kv motors. Also, taking my x8 w/ avroto 2814's apart. Thinking of building a discovery type quad or maybe y6. Looking for the 12 min flight time or so. Avroto's have all new bearings so may try them, or may sell them and maybe go with some lower kv motors. (alread have a long flying quad w/ go pro). My goal is a smaller MR, 12 min or so flying time with go pro that will handle wind a little better than my small quad. I'd also like to get 9 or so minutes when I swap gopro for a 2lb cam / gimbal setup I have. I currently have 4s and 6s batteries... 5000mHa and up.

On the 2814 size quad or y6, what size arms are you using. I have some 16 and 21.5mm carbon tubes around and center plates, so I can put something together pretty fast.

Open for suggestions!
