1s 2.5" stealth ripper

What I learnt about 1s is that weight is really important, it can completely change the way your quad flies. This 2.5" toothpick can freestyle smoothly with enough power but lighter would mean more power. It's always better to build it as light as possible.

In this case I wanted a 1s 2.5" toothpick with a bit of range to fly in the city so I used the well known Minimortal T on a crossfire Nano Rx and added to my AIO an external 450mW eachine nano vtx. It works pretty damn well, I wouldn't add any more weight tho.

The complete build is 43g, It could've been lighter with :

  • Integrated rx : my aio has an integrated 2.4 Elrs rx but I don't use it. I fly with a tango 2 and I don't want a TX + Antenna sticking out the back anyway.
  • Integrated vtx : Happymodel now makes some AIO with openVtx going up to 400mW, idk how it goes but It'd save a few grams.
  • thinner frame : mine is 3mm thick, 2mm would've been ok.
  • other : my cam and aio screws are metal, nylon could do the job. I'd also prefer using a rubberband to hold my batteries instead of this tpu but I don't have any yet lol

I fly it with 1s 520 and 650mAh and it stays in the air from 5 to 7min. It's really fun but it could be lighter. I'm gonna try 1s 450mAh soon, it should already be better. This thing is so silent, you can't hear it from more than 10m away, and with road traffic it becomes absolutely inaudible.

here is some flight footage (shitty video because of wifi in cities, but amazing range for a 43g 1s build) : https://www.instagram.com/tv/CiYTD-mjLO0/?utm_source=ig_web_copy_link

less cuts here, I was tuning it in my garden :

I'm thinking about building a 2" or 3" 1s build, I have no idea how different it'd feel but maybe I'll like it more, I'm so curious about the 1s world since it's so cheap and easy to fly everywhere.

cheers

Nice build! Which Kv did you use in this build? (I guess that it is 12000 from the pics but I'm not sure)

thanks dude, yeah 12000kv, I followed Kabab's recommendations and looked around here and it seems like the sweet spot for 1s 65mm.

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..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! 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..
