3DHawk, the ultimate 3D printed tinyhawk S or freestyle conversion.

The tinyhawk S is a good beginner quad or good indoor quad but what happen when you start fliying well and you want more of it ?
On the other end the tinyhawk Freestyle seems to be a good toothpick style quad but i read that it suffer from a lack of power...what happen if i retire 13 grams of it ?

The idea was to exploit the AIO board because for me AIO sound like weight efficiency.
So, I was limited by the 5A of the ESC and the heaviest motor i can install was 1103 8000kv with 65mm props.
I bought the skystars motor on a flash sale for 5.45$ each one.
Then I can say this build is a also a good budget conversion from a Tinyhawk S to a tinyhawk freestyle "light version"

The frame is my own design and i will post it on thingiverse soon.
It is 3" capable and i think i will test some 3025 Gemfan props wich for me are the best performance/efficiency ratio.
I add some reinforcements on the underside of the frame that i print in green with the help of M600 command on my 3D printer.

The antenna is maintained with a special part on the rear of the quad.

The original weight of a Tinyhawk freestyle is 52gram dry and 78 gram the the original batteries. My 39 and 66 grams seems to be a good progress !
I think a HD camera like the split could be installed on such a build without too much degrade the flight performance.

It run well on betaflight 4.1 with an amazing flightime of 5mn+ and a really good punch !
I'm trying to adjust the PID as well as it could be, if i find something significantly better than the stock PID i will post it.

EDIT : 28/11/2019 Today, the PID's start to be interesting, I complete a flight of 7 mn !!! With a 450 maH 1S battery, very promising !!

Hey, can you share your pids please? :) Did you try RPM?

1Smug_Bastard   Dec 08, 2019  

Which VTX did you pair with the micro camera?

Mlanaga   Dec 08, 2019 

That is the stock vtx from the tinyhawk s but you can pair a lot of nano VTX (TBS, eachine or nameless) like it's explain on this vidéo :

You can also install the tinyhawk sled to make it easy : https://tinysleds.com/products/emax-tinyhawk-freestyle-vtx-rx-sled

what filament did you use? alsoo yess!!! we need more people to work on these emax boards. I swear ive done so much to this board like its been in 2 of my micros and it has crashed several times in water but survived. I wanna see how 3" works on this so ill stay tuned for your updates my good sir!

Hi, I use a Sunlu PLA+ for the white and the green is from ice Filament. I also tested with PETG but i prefer PLA.
PLA is more rigid but more fragile on the crashes unlike PETG wich is less rigid but accept more crashes. that will depend on your driving ability ! :-D

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
