Credit to Dave_C for the pioneering work here! This is my attempt at building his vision and see how far this platform can be pushed. Still a lot of work to do, but it's built and flying! I tried a few different materials for the frame: Nylon, CF-Nylon, and CF-PETG. The frame in Nylon weighs 13.1g, but is fairly flexible. The CF-reinforced Nylon frame weighs 12.4g and is much stiffer. The CF-reinforced PETG is a little heavier at 16.2g, but much stiffer still. All printed at 20% infill. I'm not sure what the PLA frame weighs. Anyone know? I decided to use the CF-Nylon frame for this build.
I managed to get iNav running on the DarwinFPV AIO, and it works well. I've tested position hold and RTH, and will try a waypoint mission soon. At 119g AUW I'm getting 10 min flight times (40F/5C, 10mph wind). I'm sure there is significant room for improvement. Edit: Fully charging the battery to 4.2v, doubling up the nickel strip on the battery, and replacing the bad motor have greatly improved flight times.
It looks like there is a length limit for the description, so see the full writeup here: https://intofpv.com/t-1s-18650-nanolongrange?pid=133445#pid133445

do you think 0802 motors would work?
I just saw this over on RCG. If you really strip the frame down it looks like 0803 might work.

Isn't a barometer required along with GPS/Compass in order to be able to use iNav's position hold and RTH features?
what kind of flight times?
Nice build V-22! Like many others I'm also working on a 18650ish lol builds. I’m working with Dave_C frame’s using SMD SMT trays. I’m using one that will fit one 18650-21700 cell and another double 18650 tray. Heres a link to Toms review of Dave_C's fully printed build if youve not seen it.

Very cool! I've been waiting for one of these to pop up on here. I am working on one of these too. I made an alteration to the original stl by integrating a battery holder directly to the frame, just need to add the gold plated contacts. I'm interested to know more about the flight experience with your build!

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 know it hasn't been long, but how is that FC holding up? I want to buy one, but I'm a little apprehensive, since the company doesn't have a reputation (good or bad)
