In May while i flight my Fawn Saving Project, i had suddenly a Crash.
Thankfully the grass was that high, that the Lipo doesn‘t hurt ad ignit itself,
Also the Thermalcam was hung on the lower side of the Gimbal, but about 5 meters far from the Copter.
All wires ripped but i found 100% of it‘s Parts.
The Frame cracked in half and the Landing Gear brokes several Times.
As a only reason i investigated the Lipo Battery.
I flown about 1 Km far at a height of about 80meters to doublecheck my Fawnfinds in late evening.
Flighttime was 5:30 min and the Battery‘s are all fully Charged when Started.
Suddenly the Q500 fells out of heaven like a rock.
No Control was possible, all lights are immediately off when it Start to Chrash.
However, i decided to rework it, because it‘s slow and smooth gimbal was a huge benefit in fawn finding.
So i decide to rework it with a Carbon Frame.
Firstly i checked my Options and find a cheap foldable Frame platform for a 4 Rotor Copter by JMT with 60cm rotorspan.
I decided this will be a great improvement.
So i build the Frame and put it onto a scale, to see where i am with the Weight.
640 gramms seems too much, so let‘s started to reduce the Weight on all Options i have.
The first option to save was exchange all the Brass spacers to Aluminum and Nylon ones and
Even all Screws themself are exchanged to Aluminums.
At all i saved so 86 gramms. - Whow- not Bad.
Than i decided to just use 2 Screwsets for the Rotorplatforms instead of 4.
They appears to be stiff enough even with 2 Screwsets and a twist on the motors wasn‘t possible until release this 2 Screws.
Next was the implement of the Electronics.
I implemented the Q500 flight Controller near the original place to keep the Ratios as Original as i can.
Same with the compass and the rest of Electronics.
The gimbal actually was mounted just on a single gently Frame, what shall broke in case of a harder Crash.
The ESC wires must be enlarged, so i ordered also a silicon insulated triple cable with 0,3mm for wire enhancement.
I ordered 1,5sqmm silicone wire to exchange the original ESC Power Wires what was little heavier than the 1sqmm what was originally in, but for better Conduction i decided to improve it a little more
The compass was used with it‘s q500 mount, just secured additionally with a little silicone to keep it safe in place.
The last Step was to cut out the outsides of the upper canopy to have a nicer look instead a pure Frame.
So also the GPS was nearly on it‘s original place and it works like a Charme.
The first flight was a disaster, 10 meters up and tilts to nearly vertically and complete crash into a Tree in full Speed
than doing few Saltos on the Ground.
- Dang- i be a little pissed of on That.
40 bucks for Popellers are done also the endcap of batterycase riped.
The rest survived this crash without any damage.
I investigated what was the Reason and found......
Aaaaaaaah stupid idiot,
i mounted the Compass before i alligned it and forgot it to realign how it must be sat finally
and stick it the wrong way.
What wonder me, because i did a compass calibration an it appears to be fine.
- ok simple solution release the silicone, twist the Compass to it‘s final position silicone it again and redo the complete Setup.
The next few Flighttests work with 100% success.
Even up to 40Km/h windgust it wobbles shortly but keep stable back to it‘s position.
So after the Accumount rips, i decided to exchange it with a Strap.
Now it flies like nailed even in short stronger windgusts.
Here i tried it with a normal Videocam to see where was Wild boar in the Corn.
The Lipo Battery weights allone 450 gramms,
At all i ended up with a extreme robust frame at a Airborne weight at less than 1 Kilo
For a better visibility i exchanged the LED‘s on the Wingarms
Left front = Red
Right front = Green
Both Rear = White.
Similar to Aircrafts
The flashers on the canopy side have the same colorscheme to have it visible even in late evening daylight.
They will still work even the Copter may crash and the Battery stopped working.
With a running time of 2-3h i be save to find it, even i must find the Copter after a emergency landing.
