More details coming soon!!!

The price of the CineLog 25 and 30 frame kit is very similar, it is only $3 more for the CineLog $30. But it seems like you get a lot more for those 3 extra dollars. Not only is the carbon fiber frame thicker but you all get 2 spare props guards and an extra set of foam bumpers.

After building the CineLog 25, the 30 seems to be a lot easier to build. The basic layout is identical to the 25 but 30 is bigger. It felt like I has a lot more room to work with and everything fit exactly where I put it. For example, with the 25 I initially placed the capacitor right behind the rear standoff, but it was a tad too big, and the prop guards would hit it. With the 30, I was able to put the capacitor in front of the standoff and the same goes with the Crossfire Nano RX.

3D Prints
Other than the Immortal T holder, the FPV camera mount and Naked Gopro holder are the same as the 25. I remixed the Immortal T holder so it will fit on the CineLog 30 frame too. You can find the Thingiverse links before in the build details.

I redesigned the naked GoPro mount so it is fixed, because I did not like how it could move if I hit something. It is usually not a problem, but I has happen a few times where I clipped something with the GoPro and it pushed the camera where it pointed up to the sky. Plus, now I know the camera will not move and I lost a little bit of weight too (1.2g).

Initial Thoughts
Right off the bat, I knew this build will have some flaws in comparison to the existing cinewhoop style quads that I already have because of the weight. I am not sure if I can reduce the weight anymore, other than de-casing the Caddx Vista and using a Nebula Pro. The other cinewhoop (Turtle 149 frame) that I built only weighs 149g whereas this quad is 170g. I am not really concern about hitting the 250g mark but the extra 20g is noticeable in both the flight characteristics and noise.

I tried the GEPRC PIDs and some other cutoms PIDs and I did not much of a difference other than the higher motor temps with my custom tune.

would be great if you can post the pids for bf4.3 cheers

Sorry, but I have not switched anything over to BF 4.3 yet. Unless there is something specific I need with 4.3, I typically do not change firmware. I am a true believer of "If It Ain't Broke, Don't Fix It." I learned that from previous experiences.

agree, i follow the same principle :)

Do you feel like there is extra thrust, compared to it's lil brother? You mentioned that you feel the extra weight, I assume that's in the way it turns. Do you feel any extra control, or smoothness from the extra prop/disc size?

To be honest, the 2.5" feels like it has more thrust with the Gemfan D63 5 blade props and higher KV 1404 motors. The only main advantage the 30 has over the 25 is the longer flight times ( about a minute) and the slightly better stability. If you can get the Cinelog 30 around 150g dry, I think you can totally see performance gain is every way. The reason I say that is because I still have the Turtle 149 3" quad with prop guards that weigh 149g and it is very smooth, lower noise, handle the wind better and can fly very close to the ground and not feel any prop wash. I am not sure if I did something wrong with this build but 170g is just too heavy.

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..
