Simplex

Today I've managed to get my 3D printable whoop up and flying!

10-31-2020 : The .STL is now listed on Thingiverse https://www.thingiverse.com/thing:4542870 I've updated the files to remove the need for the Runcam-Nano camera adapator (its now 14 mm wide vs 19 mm), made the area for the motor wiring a bit wider and added two zip-tie locations (right & left side) to strap the battery plug to the frame.

The concept...

Simple, Completely 3D printable using PLA @ 0.2 mm resolution
Under 200 grams (151g with 4S-450 mAh battery)
Full prop guards
xx04 to xx06 motors size (Currently using 1106 Schrubkraft-4500kv)
Intergrated FC & VTX
Overall a cheep to build quad ($150 or less depending on parts sourced)

Sure there are lighter, fast better drones out there but this one I made for fun.

Please note: Added the plot responce from the maiden flight. P-Term looks a bit too high but it flew really nice just using the BF defaults.

Youtube Video of 1st Acro flight. It did really well despite it being very windy outside:

Its quite possibly under proped as I didnt see the current go above 10 amps the entire flight. Either that or the current calibration is out of spec.

Woah! This thing is awesome looking! It reminds me of that BNF you can get, the FUS111. I love that so many probs with current frames can easily be solved with this move to a 3d printed frame! The fastener customization possibilities! You can just make a custom mount for ANY board you can fit in there, so awesome!!!!!
Why not just make the cam mount narrower, I see you used an adapter there?

So I have printed a 3" frame in PETG and had it fly well. Used Dave_C's starfish design.

This 5" one ? https://rotorbuilds.com/build/15662

I'll upload the Simplex 3" frame sometime tomorrow for you to experiment with.

Apparently my current scale was way too high. Should be 210 but it was set at 400 from the BF defaults.

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..
