|=============] CHALLENGE : Sub 250 - 30 min - 10K [=================|
Last Post
The goal is to match the performance of the DJI Mini which is a commercially built quadcopter that will fly for more than 30 minutes and has a range of 10K while having an AUW {including battery} that is less than 250 grams.
Initially, V-22 started a build that would be sub 250 gram, have a DJI system, and would match the DJI Mini’s performance of flying for 30 minutes and fly for a total distance of 10K.
[Build] 3" 250g 10km DJI Digital Build
Finding these goals interesting, I decided to also build a sub 250 gram AUW quad with analog FPV and meeting same flight performance metrics: 30 minutes Fly Time and 10K Total flight distance.
[Build] Quest250-LR
From here, others became interested.
In order to match the DJI Mini, the quad must be able to fly for 30 minutes and fly at least 5K away from the transmitter and Fly a total distance of 10K while NOT exceeding the 250 gram AUW limit.
The CHALLENGE :
Sub 250 gram AUW: Total in-flight weight including battery and any payload, while
also meeting each of the following criteria. The sub 250 grams AUW
is an overriding criteria that must ALWAYS be met. The DJI Mini
meets both of the following criteria while being under 250 grams.
Fly for 30 Minutes: Be airborne for 30 minutes AND be sub 250 grams.
Flight Distance of 10K: AND be sub 250 grams; Just Like the DJI Mini.
Part A: Fitted with Long Range receiver and powerful VTX,
flying for a Total Distance of 10K demonstrates that
the quad technically matches the performance metrics
of the DJI Mini.
Part B: A flight video out to 5K {away from transmitter} and
logging a total Flight Distance of 10K demonstrates
that the quad matches the DJI Mini's actual performance.
The FPV video subsystem can be digital or analog, but still needs to be long range.
Also, there needs to be a recording mechanism; either goggles or on-board that shows OSD info.
The flight video needs to show the Fly Time, Total Distance, and it should also show
the distance from transmitter.
No Limits or constraints for Quad Size or Power Source.
Considering that this is a Long Range build, it would, out of necessity, need to have
a Long Range Rx receiver and a powerful VTX that is capable of reaching 5K.
Although a GPS is not specified, it will pretty much be necessary to provide data
as proof that the Challenge criteria have been met.
PROOF requirements:
1) A build thread with pictures showing the components, the progress, and the completed quad.
2) A picture {with battery} of the quad on a scales showing the All Up Weight, AUW at less than 250 grams.
AUW must be LESS than 250 grams for ALL flights
3) A flight video with the OSD showing the Fly Time.
4) A flight video with the OSD displaying the Total Flight Distance for Part A.
5) A flight video with the OSD displaying the Total Flight Distance and 5K out from transmitter for Part B.
The videos should be full length {time compression is ok for the middle of the flight, but still need to see the entire video}.
NOTE: The Fly Time and the Distance Do NOT have to be in the same flight;
just be able to do both while still having a sub 250 gram AUW.
The Fly Time criteria is that the quad be AIRBORNE for 30 minutes.
A separate flight for Distance is fine, once 10K is reached, that meets Part A.
Going out 5K from transmitter and reaching 10K meets Part B.
If ALL criteria can be achieved in a single flight, GREAT, but not a requirement.
The Challenge is open ended and on going.
Any build, at Any time, can attempt the Challenge...Now and in the future.
Although you won't get a badge, view this similar to a badge;
at any time, anyone, can BUILD a quad for the Challenge.

I have now fixed that "confusion" 
From this day forward it will say "min" for minutes
