Back with another Armattan build -and still having fun with the title :P
Here's a pretty neat build that surprised me with it's up to 8mins flight time on HV 3S GNB 520mah.
It's an excellent daily flier I've been ripping every morning at my local park; it's size and stealth make it perfect for those smaller spots in bigger cities
What impressed me the most was the insane Thrust/weight; it hovers at about 25% throttle and boi does it accelerate fast; very forgiving coming off dives and low altitude spins.
Weighing at 115g operational weight this thing is also a leaf; airtime is loong :)
It's also running perfectly Emuflight 0.3.2 on STOCK pids/filter (3S 3" preset); incredibly locked in out of the box
And most notably Jazzmac's BLHeli_M with 48khz PWM - Certainly the largest contributor to the crazy flight time
Overall super happy with it; that's the build I have been waiting for
The build came with a couple challenges if you're looking to build one for yourself:
And ther's that; here's a little edit, not mine; found the SD card ;)
Cheers!

Hey, awesome build! I am a total newb and purchased a runcam racer nano 2 and noticed that the connector is too large to fit into the plug on the FC. How did you connect your Runcam into the FC? Adapter?
Hey just a word of caution: I have a super similar build (Tadpole 3", Gemfan Hurricane 3028 props, 1204 5000kv motors) and kept burning up the motors in crashes. I believe 5000kv is a bit too high. It's right on that edge where it's okay for quick punch outs and normal flying, but in crashes when PID loop freaks out and motors change direction crazy fast they eventually burned out. If I knew better beforehand I would have set an 85% or even 80% output limit to prevent them burning up in crashes.
Mine flew fantastic for about a month until they started burning out one by one. I've used up the two spares I ordered and decided to go to a lower KV instead of getting the same ones again. If I had thought about it before placing the order I would have set the output limit. I don't think you'd even notice it. Just a thought :)
So I don't have video of the 5000kv on 4S, but I posted DVR on my rebuild (3700kv) if you wanna check that out:

Nice build, I to was impressed with the flight time of my tadpole. build's here: https://rotorbuilds.com/build/25136
I was getting 8 mins. easy. I recently changed motor speed to 48khz and swapped my gemfan props for Emax avon 2.51.93 simitar props. it all added 1.5 mins. give and take .5 min. on flying type. I love these little tadpoles. Again, great job on the build.
I'm still doing alot of testing. So far I've found out that battery resistance goes up as the battery drains. If battery resistance exceeds motor resistance efficiency goes down. I've been matching dead cells resistance to motor resistance. So at full charge the battery resistance is low and working its way to motor resistance to keep efficiency as high as I can.
AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

can those 1204 5000kv run 4s?
will 12a esc be enough if run 4s?
thank!
