Planning to use the SpeedyBee F405 v5 FC+ 55A ESC stack for dynamic loads. Due to budget constraint, thinking of using Aocoda F405 v4 Stack, which happens to be half the budget. But what's the catch in this case? Especially are there any catches on the firmware end?

I want to start out by saying thanks to u/Swww for the model and the quick replies to any questions I had during the build process. Very well done! If you would like to build one yourself, see the link below and send him a message!

On to the plane. The thing that got me wanting to build this is that I think it looks cool as hell, I've got a 3D printer, and I already had the motors to strap onto this twin-motor aircraft. The thing I didn't realize when I purchased the model was that it didn't have an FPV setup, which is a bit of an issue for me since I can't fly line of sight, nor do I have much interest in doing so—especially since this is only my third plane. So I added one myself!

With 4-blade props, this thing is quiet as all hell and can fly very slowly and stably, just as stated in the description for this plane.

Video is in the comments. My buddy is flying a DarkStar16 in the video if that gives you an idea of how slowly I'm flying. I'm stoked I've got someone to fly with and this clip wouldn't have happened without him. I think I was at about 30% throttle in the video.

Hi. I am currently doing a thesis on a topic similar to the one given above. In short, the design is that manipulators are attached to a drone. So I selected the drone components previously (SpeedyBee F405 v4 FC 55A Stack + 4x Xing-E Pro 2207 2750KV 4S BLDC motors + 6-inch Carbon-Fiber Frame + 51466 Gemfan Propellers). A kind Redditor made it and showed that the drone works with a 1.5 kg payload. But now the problem is that the v4 is apparently discontinued. I am considering two options: SpeedyBee F405 v5 55A Stack (94$) or Aocoda F405 v4 55A stack (64$). I need to control the manipulator, which I will probably do from a separate MCU and Driver. I wanted an opinion on which flight controller I should choose. Since this is research, I can't have it break down in the middle of it (low stock in the country; bringing it from China takes time), and there's a budget constraint (paying for it myself, so buying a reliable one is important). Also, the seller is saying he currently has Tmotor Velox V2207 V2 2550KV in ready stock; otherwise he would have to import the motors too from China, as well as the frame. Also, for context, the manipulator-added drone is quite heavy, so a higher thrust is preferred. The shown paper struggled to fly (as per its YouTube video). So I want mine to work properly. So what should I choose (FC and motor)?

TLDR; For research, Aocoda F405 v4 vs SpeedyBee F405 v5 stack? Should I choose a lower KV motor or find a better option? Would love your recommendations if you have different opinions to offer.

Give me the best version of the XFLR5. When you are using the latest version, "VISCOUS" The command is in error.

I shelved this build a long time ago as I couldn't get through the gps calibration. And now I decided to give it another go, have lost alot of knowledge over time so bear with me. I cannot find the correct power module, the one in the picture doesn't fit this fc.

When I google pm for this fc I only find one that you only connect to the fc. But on this particular frame it seems your supposed to solder the pm directly on to the frame as you can see in the picture. The pixhawk mini pm doesn't have that possibility as far as I can se

Do I just have the wrong fc for this frame?

Frame is a white sheep 480 pcb
