"10+ Kilowatt, 127mm EDF Delta, CROWD CONTROL!

10+ Kilowatt 127mm power.
Today visiting one of the local cow paddock flying field having a ball at this rather restrictive
flying facility, not being allowed to fly over the dairy or the road, making approach bit tricky with
larger models as seen in attached video, slightly overshooting short strip by 20 feet.
Some downloaded data after this short 4.5min. flight with Throttle never exceeding 80%.
Voltage Max. 50 ave. 46.
Temp. 148/104
Amps 220/30
Watts 10050/1370
Interesting country site video, next, Happy and safe flying.

What kind of batteries can take that abuse?

Scorpion 650kv/modified CC160 ESC.
220Amps is conservative figure at 80% power output, at full burst it draws 250+, at well over 12Kwatt. As I said in my above post average current draw during the flight in the video was only 30 Amps. Most of the flight time was performed at 40-50% power output, but it's great to have it as spare if needed. Look, my car can reach 200km/h but I never drive it more than 110.
BTW, the batteries are up to 130C rate handling the currents with ease, Happy flying.

Thanks guys, Rog, yes, it is very pretty site but the crappiest flying field for large models. I have been there twice but probably the last time, you have to bring the gum booth, the cow poo is everywhere, I can still smell it. The Amp current seem pretty high but I rarely have to go to those extremes figures, I always like to have few spare coins in my pocket if you know what I mean. Regards, J.

My personal 'best' today, 6 minute flight time with this 127mm powered model, using 8Ah packs, just nice scale cruising around the field with only one fast full stick pass along the strip, another magic day.

that's a foam based model you made , correct? small batts.
I just find the numbers tough to believe considering the lack of performance. incorrect ESC settings give wrong readings and many just give false readings all the time. just doesn't sound or look like 200+ amps. just my worthless opinion. does fly well though!

Believe it on not, 10kg thrust, clamp e-meter check, taking off on 1/2 stick, 6 min. flight time while using 60C+/8Ah packs and 5 years of happy flying is good enough for me.

Again I ask, what kind of batteries can take that abuse?
You throw wild numbers out there all the time but don't bother explaining the useful information of technical details. What motor, fan, ESC, batteries etc?
Who assembles the fan, how was it balanced, how much thrust for an exact power level posted in watts?
Pictures of beaches helps nobody benefit from your experience IMHO.
Care to divulge other useful data like flying weight, flight times and power consumed? How about what retracts you use etc? Also interested in what gauge wire used and connectors used both for the batteries and motor wires.
Thanks in advance!

Stripy, to experience such amazing figures you would have to build and fly models of this calibre first.
I'm not here to sell, promote or trash things, simply sharing success or failures with my builds.
If you read my posts instead just looking at beautiful scenery pictures your above questions were answered
numerous times in threads, posts and videos featuring this unique model for the last 5 years since my disastrous maiden
or even more spectacular "fire on board-May-Day-May-Day" footage. I can assure you that 6S powered foamy is no match
to this one. 3.5-4kg of heavy duty lipos handle the currents with ease. Regards. (pic. 5 years ago after my disastrous maiden)

You missed my point and still haven't answered any technical questions.
How are your posts helpful to anyone wishing to advance to your level?
