Oh duh I didn't think that you need the GPS for proof lol duh.

Man I have no idea then. That GPS was really the big weight saver I could think of.

Hi Ronin,

Yeah, I don't think flying down the Interstate counting mile markers is going to work. Well... I guess if you can accomplish that and clock 7 miles {although you only need 6.4, most Interstates only have even mile markers so it would need to be 7 to be sure}, then we might take that into consideration. 

Come on, man, you can loose 5-10 grams somewhere else. I am looking at a custom fabricated fiberglass frame. What do you think 

Hi iFly, I will put my hat into the ring for this, just wanted to show a quick teaser before I create a build thread sometime hopefully soon. 

It's a 2S li-ion remix of the Dave_C nanolongrange frame.   I'm calling it the hotdog, lol.





cheers,

Hi ph2t,

I like it. Start a BUILD thread and I will add it to the list of Participants in the Challenge.

It is very interesting and I look forward to the progress and the results.  Get that BUILD thread started and PM me with the link. I will add it.

Thank You.

I was thinking a reverse tri-copter with the GPS out the back just to save weight on one less motor. The thing doesn't have to tune well or do acro so that's what got me thinking of getting rid of a motor.

Hi Ronin,

Well now, that is a thought. Since there are no motor criteria you could definitely do a tri-copter. 

Also, check out this 1.6 gram NamelessRC Tiny GPS Module. I will pick up a couple on my next PyroDrone order.

So the FlyWoo LR 4" with side braces 149gm without battery.
With a 4S LiIon its 350 gm and would do the 10Km, and just might barely do the hover on a good day while destroying the battery.

Just a reference point the DJI mini must be well optimized...

The Flywoo LR 4 does not meet the Challenge criteria since the 4S Li-Ion pushes the weight over the 250 gram limit. This is NOT the type of craft that we are working on. Keep in mind the goal is to MATCH the performance of the DJI Mini which will fly for 30 minutes and fly a total distance of 10K all while being less than 250 grams of total fly weight including the battery.

Just to clarify, the craft must weigh less than 250 grams with battery...for the Fly Time...AND...for the Distance. Although the two flights can be separate the AUW must still be less than 250 grams with battery.

the explorer could join if used with a 2s liion, or with another 100g 2-4s lipo

Let's think about this.

Well first, it wouldn't be a build so it really wouldn't be a challenge BUILD. The Challenge is to BUILD a craft that matches the DJI Mini performance metrics. 

The other interesting thing is that I have NOT seen any ready-to-fly quad including the Flywoo Explorer that can make the time nor distance on a 2S battery; at least no one has shown this. Except, that is the DJI Mini...and entering one of those is not the challenge. 

Think about it.

i missed the selfvuild requirement, makes sense :-)

about 2s on the explorer, i believe that matches pretty well for 2s, the original 4s suggestion seems strange, for flighttime/range, to me xD

Hi Bat,

I don't think the Flywoo Explorer or any other of the 4 inch LR BNF's will make the time nor the distance on 2S, that is why they use 4S...Even a 3S will generally not get a 4 inch to 30 minutes Fly Time...distance aside.

From what I have seen, the DJI Mini might be the only commercially produced quad with those specs.

That is what makes this Challenge interesting.  Can one of use match that performance with one of our own builds ???

I believe that it is possible, but will likely take some work. 

Hi ph2t,

Did you get BUILD thread started for the "HotDog"? I have been looking, but can't seem to find it.

You can post the BUILD link here or send me a PM.

Thanks

Hey iFly, have posted the build thread mate and sent you a link.

cheers,

ph2t.
