The story behind the build

Nothing special...
I saw this extraordinary frame and I knew I had to build it ;)

Choice of components

Ok, the frame was set, so I watched out for the motors. They should be lightweight and fit the M2x12 mounting pattern.
I also wanted to add some color this time, which lead me to the rcINpower GTV V3.
This build should also be a bit crazy, so 6S ws the minimum -> 1850 KV.
For the mini size stack I wanted to try Diatone, because I think the are top notch, I haven't tried them yet and they were available!
Unfortunately I noticed to late, that the Mamba DJI F722 mini MK2 doesn't support blackbox logging.
For a lightweight frame with plenty of power (and added weight) I definitively don't want to miss blackbox logging, therefore I switched the FC to an Aikon F7.
Digital was set anyway, and after my first experience with the Caddx Polar, it was clear to take Polar again.#
I didn't want to have this big LED show, but for a little bit of color, I decided to give the TrueRC Blaze a try.
The props should be 5.1", but very low-pitched because the motor doesn't have that much torque.
That's why I chose the Gemfan 5125 SL. I think "SL" stands for superlight - and yes, they are: 2,9 g per one!
So here we are, let's build this thing...


The build was very great fun, at least to me...
This frame offers to little space to just arrange things, I had to find a custom way to fit everything in - and I love that.
In the inner space, there is enought heigt for the FC and ESC or FC and Vista. But the mounting holes for the FC are so filigree, that I was definitively doesn't want to fix the Vista there and also had some headache to fix the FC-ESC stack. Thats why I used them only to fix the FC and put the ESC under the topplate, which wasn't meant to carry anything. But I tought the ESC will be ok...
So the only space left for the Vista was inside the frame. To get the needed height and have an opportunity to fix the Lipo, I had to build an additional bottomplate.
But with this, I was able to build a seperat "video module" which could be detached easily .

Flight quality

The first trial was catastrophic the copter flew, but at the end of sharp flips or rolls it freaked out for split seconds - really scary!
After some flight I found the superlight props to be the problem. I changed them to HQ DP5.1x3.6 and this problem was solved.
With this props the copter flies really good, but the voltage sag is pretty heavy. I think the 6S 650 mAh I used are to small for this setting.
I'll watch out for 850s or 1050s and try again.
But beside of that, it a really fast and agile copter!
And I'm really curious how it will perform with bigger batterys and a good tuning...
I'll update, when I tried the bigger batterys.

Now, I have some 1050 mAh batterys. But they feel just too heavy for this frame.
That's why I reduced propellers's pitch instead of increasing battery capacity - and it works.
The 5130 props really fit this powertrain.


Weight with props: 241 g
AUW with 6S 650 mAh: 354 g
Flight time (650 mAh): approx. 2:30 to 5:00

Sick build! How do you like these motors? Think Im going to get them for a 4in 4s.

MamaJOE   Jan 14, 2022 

Thanks, I take this as a compliment.
Till now, I like the motors, they have no bearing play and are running smooth.
For 4S you will use the 2950 KV motors, right?
I think for a 4", they will have plenty of power. Give the 6-blade props (see my KISS of Calm build) a try ;)

Craftedkwads   Jan 14, 2022 

I am thinking of the 3600kv version and limiting it to 3000kv, because those are the only ones I can get in gunmetal and gold ;) Do you find that they are decently efficient, or are they more suited for a racing build? I want a freestyle build that I can limit and put different props on to give it good flight time for range.

I'm not sure if this motor is the right one for long range. I achieve 5 min flight time with 650 mAh easily but I think it's rather the light copter, than the efficiency of the motors. Perhaps the Emax ECOII 2004 will be perfect for your needs? For a lightweight 4", they should have enough power...
Here's why I would suggest them:

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..
