PNut 2.5"

Super easy build with the Mayday PNut frame. So easy it almost doesn't even count as a build, but I guess soldering the RX and LEDS were a little challenging on the 16x16 board. Other than that, piece of cake. Everything is conformal coated. Total weight with battery strap, rear LED, and arm bumpers is 62g. Without all of those it's 57g.

I'll likely shorten the XT30, and may add a small capacitor. All 3D printed parts were included except the arm bumpers, which are available with the other parts on Mayday's Thingiverse.

Would you know if it can take a bigger battery.

d3c0de Feb 04, 2020

It can, but I feel like this size is pretty ideal. Getting over 4 minutes of flight time on average now with 48kHz ESC firmware. The next size up GNB battery is 650mAh, and 3.5g heavier. Doesn't sound like a lot, but that's nearly 4% of the total weight. If you're not planning to race it though, it'd probably be fine.

Do you know any other frames that might work for this build.

d3c0de Jan 23, 2020

It's similar to the iFlight TurboBee 120RS frame, but is a bit stronger. Some local pilots switched after breaking the iFlight frames too frequently. Another frame I might look at would be the Diatone GTB229, based on what I've heard, but I don't have any first hand experience with it.

Build a 5" Long Range Drone - Transformer Ultralight

Jun 21, 2021

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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
