I wanted to make 10 minutes+ long range slow flyer. I'm going to get 2s3p 18650 packs for it.
381g w/o battery. Looks 281mm frame could take 7 inch props and not hit the base.
Edit: I've got mentioned custom battery and it flies beautefully with 2:1 weight ratio, 6535 props. 15minutes of actual flying. I crashed (light, nothing happened) and I think it was low voltage ~7V (3,5 per cell) and, so either FC doesn't supply power to 5v of RX or one of the ESCs shut down. Looks like I'll try connect 2 such batteries in one 4s3p. Blackbox was full...

Very nice. How's it fly?
Bad weather, my first build process and debugging stopped me to try the range, real flight time and characteristics. I did a few LOS flights, blackbox shows me very clean build. Surprised how much power it has on 3s as I only flown toys 2s till now. IDK really, need more experience and FPV flight to tell. It flies :)

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..

I haven't seen anyone try this on a multirotor. I have seen it on single prop decent/high effeciency rc planes. Typically the accepted wisdom is tat the amp draw on a multirotor is too high for lythium ion, but I would love to see what you get out of it. I would imagine a lower kv motor would serve you much better in this endavor, but I still hope it works for you. Please post a vid when you can, I have toyed with the idea of doing this but got discouraged after researching, i'm glad you're doing it!!
"ecalc" calculations says 2s3p pack (5c per battery) should do
15km flight distance (best case scenario)
min. Flight Time: 10.8 min
Mixed Flight Time: 29.0 min
Hover Flight Time: 43.6 min
with 2,5 T/W ratio
I'll give it a try :)
DiodeGoneWild did a test recently on an 18650 that did almost 30A but only at about 2V for one second or so. With 3P it might be possible if you are real easy on the throttle.
Li-Ion 2s3p (300g) over 16mins armed/flight time:
Still running those 6" CF 2 blade props?
T-motor 6535 props, sometimes KingKong 6040. At the moment I fly 6inch front and 6.5inch back to have equal thrust on fron and rear - experimenting - looks like less vibration.
