This is 2nd build for freestyle frame which is called TransTEC Freedom V2 (5inch). According to the TracsTEC Spec. the upper shell is made by CNC 7075 Aviation Aluminium-alloy. The point of attraction is the arms thinkness which is 6 mm. It looks super soild.

Goal and Parts Selection

Recently, i have experienced bad flying with not enough strong statement. For example, the screw or nut or some parts(broken and cracked plate, arm) could generate some jello or vibration or noise. The goal of this quad was to build , a frame must be strong enough in machanical properties like as a frame of racing car.

Frame & Build Tip

All parts are not finished the edge of carbon by some poymer material. The edge has not cutted so i finished by my hand with sand paper.
The arm thickness is over 6mm. Actually, two of them are 6 mm and the other two of them are 6.2mm. I used 6.2mm arm for front arm. bottum plate is 3 mm. it super strong enough with arm. The screws are something is supplied 10.9 and 12.9 class. it's looking good. The space is not enough for parts so i recommed to use single ESC. but i haven't got the single ESC. I just used 4 in 1 ESC. My HD cam is Yi 4K and i desinged HD cam mount for Yi 4k which is fixed with 30 mm screw at the front rear is hold the cable tie.

Flight Test

I've tested all of default setting with butterflight firmware i haven't changed PID and filtering. It's super smooth and flying like a clean now. In the future, i'd like to record flight video wwith this quad. i really expected.

AUW(all-up weight) is 705 g with battery, propeller and action cam.

I'm going to record the drift car chasing video with this drone and the other one which is Puda D240 frame. It's also great frame.

Hi KuriOSS, could you please share 3D files of Yi camera holder? I'm also courious about the lens filter, do you have a link to it?
Thanks a lot!

KuriOSS   Jan 04, 2020 

i sent the e-mail directly! thanks, mate! updated new version has been sent

___anvy___   Jan 07, 2020 

Thanks mate. Could you tell me what printing material did you use? Thanks

KuriOSS   Jan 07, 2020 

TPU filaments are used. i'd asked about machanical properties(tensile strength, melting poiont, density, elongation at break flexural modules) to seller(Korea). they can't answer about it. they said it just TPU, lol. Anyway, It's pretty good.

This is HOT!! I've just build a transtec myself! Would you mind sharing your 3D STL files? Especially the gopro mount, this frame really need a special mount. I've been scouring all over the net for this, and yours look perfect!

KuriOSS   Aug 25, 2019 

Yes, it is really cool design and cheap. Also, frame is super strong enough. I really like it. I have sent the msg for you. please contact me when you can't get the msg for STL files. Have a fun!

Oh my god this is beautiful! Well done!
I'm super impressed with the TransTec frames. They are nearly indestructable and fly really good!

KuriOSS   May 19, 2019 

Yes, it is beatiful design. I just tested it now it is still good enough!

6mm Carbon!!! I've got a TransTec Frog and its indestructible. But this thing takes it to the next level.
Love the build.

KuriOSS   May 16, 2019 

Yes, it is. I tseted it shortly today. No need too much filteration so that it flight performance is response than bad condition frame. Recently, i really interested in machanical property of frame. thanks for replying and giving like button! Have a good day!

What a sexy frame! I have looked at that one on banggood for weeks now, it looks like a great design. I like your layout, and i'm impressed with your antenna mod, how is it performing?
Great build!

KuriOSS   May 15, 2019 

Thank you for your compliment! The flight is soo much smooth and easy to control. It could be my main quad after finishing setting(PID and filteration). This frame feels like strength of mechanical. i have tried to bend the the end of arm to the other arm but it can not be bent. super super strong enough. Disadvantage is limited space of parts so i highly recommend to use individual ESC.

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..
