If you are looking for the best possible flight experience with a cinema FPV platform, then you have come to the right place. Le Pigeon flies like a simulator and with an AUW of around 1.6kg including battery and lens, you are no longer restricted in your flight maneuvers. Unlike a normal cinelifter which weighs around 3500g or more, Le Pigeon is an absolute joy to fly and opens up doors for your creative potential. This is the culmination of 3 years of my dedication toward the pursuit of the ultimate cinema FPV rig.
Many advancements were made since the original "Le Pigeon" drone I designed. The biggest of which is my upgraded naked BMPCC4K cage kit that contains 5 flexible PCBs that drastically improve the workflow and interface with the Blackmagic Cinema Camera.
Another big milestone is my new H layout for the frame. It's still a 7 inch quad, but with my intergrated damping of the arms and special attention to minimizing torsional weakness inherent to H frames, this frame has much less vibration and can be used with a wider variety of propellers and motors.
MOTORS OVERVIEW:
The following assesment is very subjective and is limited to the scope for use with Le Pigeon only. I have personally flown all the motors described in this list. In summary, most people will be very happy with any of these six recommended motors with a 6S setup. My personal favorite is the Xnova 2808 1350kV and that's what I'll be using on jobs and my own videos.
RECOMMENDED ESCs
The best ESC I have tried personally is the Aikon 55A V3 (the longer one). It is smooth as crap! It is a huge ESC so I made sure that Le Pigeon frame can accommodate its dimensions. The next contender is the Foxeer Reaper 65A 3-8S ESC. I have used 3 of them and had no issues at all and they all flew smooth. I have also had 100% success rate with about a dozen Hobbywing 60A ESCs so those are usually a good bet. I have not tried the T-Motor 55A ESCs, but I have heard great things about them. Now if you want to go overkill or perhaps want to experiment with 8S, then I can recommend the iFlight 80A 4in1. I have tested two of them for experimental rigs and subjected them to a lot of abuse and had no issues and they seem pretty bomb-proof. As far as capacitors go, I recommend a 50V 1000uF or higher cap soldered to the battery tabs of the ESC using shortest possible lengths of 18awg motor wire. The diameter should be around 12.5mm and the longest it can be is 37mm to comfortably fit inside the frame. How do you find a low ESR capacitor? Watch my guide here:
BL_Heli 32 SETTINGS
I recommend 24kHz for most of the motors I mentioned before with the exception of the BH 2810 1500kv. At 24kHz, the 1500kV motors run too hot and it is better to run 48kHz and increase the PIDs a bit to compensate for the reduced power at low RPM. With 24kHz, all these motors fly like they are on rails when you let go of the sticks and let it cruise on its own.
FLIGHT CONTROLLERS
The best flight controller I have tested is the Foxeer F722 V2 because not only does it have the MPU6000, but also a larger 3.3V regulator which offers cleaner supply power to the gyro and other components. I do not recommend the Matek F722 HD because they are having batch issues with their MPU6000s and some of their FCs are getting massive noise only on the pitch axis. I can recommend the Aikon F7 HD flight controller because is has the MPU6000 and Aikon is a solid manufacturer. I have not actually tested this FC myself though, so be aware of that. I have also used the Rush Blade F722 FCs and I recieved one that was DOA, but the ones that worked were easy to tune. I have not tested the Hobbywing convertable FC yet because it has the ICM20602 gyro, but I bet you it would work just fine because Le Pigeon is such a low resonance frame.
PID TUNING
I may make a PID tuning video with Le Pigeon in the future if I have time, but for now you may use the screenshots below as a reference point. These PIDs and filters are with the Xnova 2808 1350kV motors (on 6S voltage) with HQ 7x3.5x3 propellers.
REGULATORS
The best setup is to have two Pololu BECs. A 9V 2.6a one for the DJI air unit and a 12V 2.4a one to power the BMPCC4K. There is also a 12V 4.5a Pololu regulator that you can use to power both the air unit and the camera, but I like the redundancy of separate BECs for each purpose. I always solder a small 35V 220uF capacitor to the INPUT pads on the boards to further filter the power coming into the regulars and protect them from any voltage spikes that may cause them to shut down. I do not recommend relying on the flight controller 8-9V BEC to power the DJI air unit because this is a higher power build and the FC probably doesn't have enough filtration to protect the air unit from voltage spikes that can cause it to glitch out or even reboot.
PROPELLERS
As of 11/23/2021 the best propeller for Le Pigeon by far are the new HQ 7x3.5x3 durable transluscent gray ones. They are the best 7 inch FPV propeller ever made in my opinion. So smooth and free of propwash despite it weighing a hefty 8.8g. They are extremely well balanced and seem to have the least amount of vibes. In addition they are fast enough for me yet get better flight times than the old HQ 7x3.5x3 props. The thrust curve on it is also very linear and predictable (a valuable trait for cinelifters). Lastly, they are actually durable and you can a hit rigid obstacles and stay in the air if you can recover right away.
The new HQ 7x4.5x3 macroquad props are decent and fly similar to the pure polycarbonate version mentioned previously, but they are faster and will eat your batteries quickly. Also they are not as well balanced and may cause some minor vibrations. They are not as durable and will explode if you hit branches due to the glass/nylon composite material.
The DAL cyclone T7056C used to be my favorite, but someone with a V1 Pigeon had one explode mid flight for no reason so now I feel sketched out by them.
The new Gemfan "Cinelifter" 7035 carbon polycarbonate props don't work well on Le Pigeon. You can distinguish these because they are glossy and come in both black and white. I think they would be well suited for a 7inch GoPro rig with motors that are only about 1100kv for long range use. Under the extra weight of Le Pigeon, they sound like they are straining (only weighing 4.3g each) and the noise they produce is quite unpleasant. At the uper 95% throttle with 1350kV motors, the Gemfan 7035s begin to flutter, causing the loud BRRRRRR sound when they reach their RPM and/or load limit.
Now Gemfan also has 7035 and 7037 carbon nylon props which are quite a bit stronger and stiffer. In addition, they have gray polycarbonate 7037 props too. These props are not tested by me yet, but do seem promising and deserve a link below.
BATTERIES
LENSES
I have personally used the following five lenses that I recommend on this page. My favorite is the Laowa 7.5mm (ultralight red version) because it is so wide, crisp, and makes your flights seem dynamic and exciting. My only gripe with this lens is that it could be even lighter and also the rectilinear stretch, although favored over the fisheye effect, noticeably distorts the image at the corners. The best ND filter for this lens is the NiSi pro 46mm which screws directly into the front and causes minimal vignetting due to its slim outer ring.
I used to recommend the SLR Magic 8mm because it is so light and inexpensive, but the issue with it is that it is difficult to get a perfect image out of it. The sweet spot for aperture range is narrow (around 5.6-8). In addition the rear element is quite small because it is not a "fast" lens. This means that if you stop down the aperture too much, any tiny speck of dust is going to cause glare or blurry spots. If the aperture is too wide, then the image gets soft around the edges. Also, the front lens element bulges out and may touch your filter even with a step up ring so that is a whole problem to figure out in itself.
I have used the Samyang 12mm and it's on the heavy side at 255g. You can do a lot with this lens, but the flight performance and efficiency may suffer a bit. I love the image though and it is great value for the money.
A better alternative to the Samyang is the Olympus 12mm, but at $700 you really pay for it. I got mine used for $400-500. At 130g it is one of the lightest lens options and its low light performance is spectacular. 12mm is too tight for most FPV style shots, but I always like to keep a narrower lens for getting "closer" to the subject if need be.
I used the Laowa 9mm zero-D cine lens once on set and the image is fantastic, but it is still on the heavy side at 247g. The compact form factor does help with optimizing the center of gravity though. I think 9mm is the ideal focal length for most people if they had to choose just one lens.
The Laowa 10mm lens is a popular choice for Le Pigeon, but I have not used it myeself. A known issue with this lens is compatibility issues with the BMPCC4K due to the firmware on the lens. It's a crap shoot, you may get lucky and get one with the correct firmware which is compatible with your pocket 4K. Or you will get a lens that does not communicate with the camera and all the functions like aperture and focus are disabled. To fix this, you have to send it back to Laowa and they will either replace it or load new firmware and send it back.

Le Pigeon Build Overview
BMPCC4K Cage Design
This is insane! True blending of a camera drone and FPV, in a way most only imagine, or play at.
Quad-porn to the extreme
Makes me want to build one SO bad!!!
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..
Read moreWith 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..

Can you share your methodology/data for testing the different motors?
If the PID tuning is kept constant, it will favor the original motor which it was tuned for.
How did you test for the input response? Did you tune every motor setup for the same input response then run your performance(endurance/heat) tests?
Hi, yes I did different tunes to work with each motor since they all had different kVs. I did not do a "scientific" test and analyze blackbox data so if you're interested in that, you can disregard all my notes. Instead I flew the setups back to back over the course of a few days and noted my subjective observations about the characteristics of each motor. Bench tests and blackbox can only tell you so much.
