Hey All, I've experienced nothing but problems with my Larva and it's CrazyBee flight controller. Several have blown their voltage controllers so I lose VTX, and the durability just seems to be not great, to the point that even using a voltage regulator to power the VTX and a crash results in a dead FC. So, I want to be able to repurpose my frame, vtx camera, receiver and motors if possible but swap essay writer out the FC to something a little more robust. I've been flying with the GNB 300ma 3s batteries and some HQprop triblades, so I want to get something that has the same kind of punch and feel and be able to use my batteries that I currently have.

the larva does use the crazybee f4 pro ?v3?, this version of the aio doesnt have quality issues or hardware problems as i know. i flew ghis board on a larva and later in other configurations with 1106motors. actual a buddy enjoy it.
i like this fc and would buy the larva again xD to get it with good value for money... overall with the other parts its good value.

you will need to adjust the pid settings on a new board to get the same peformance, if you are a beginner and wont mess around with pid, i would suggest the original board.

i didnt understand it enough, sry my english, your quad stays on the ground because of sn issue?
if yess, my way would be a replacement larva for 80bucks and the orevious as spare oart delivery platform.

nameless rc would have an aio f4 2-3s 12a, pretty the same specs.

I had similar issues with Crazybee boards.

I've had better luck with JHEMCU FC's, and they are a bit cheaper. .

Hi RileyDylan,

I agree with Manning. I have used the JHEMCU brand in a lot of my builds. The JHEMCU GHF411 board should work fine; it does come with motor connectors, but you will need to solder them on if  you want to use them. One thing to be aware of is that the USB connector is side mounted rather than down, so you might have to notch one of the "whoops" to connect to it. Also, use a right angle USB adapter.

I am also a believer in GEPRC products; I have just received a GEPRC Stable 20A Toothpick/whoop F4 AIO w 200mW VTX to put into an iFlight 85mm whoop frame. I am always impressed with the GEPRC quality; the board feels solid, the VTX is already connected, and so is the XT30 battery connector. Now, I will add an FrSky XM+ receiver, add a Foxeer camera, and connect the motors {maybe GEPRC 1202s since I want a "house" cruiser rather than a Pocket Rocket}. Same thing with this FC, USB on the side.

For me, the USB connector location is no big deal. What I look for is a solid FC that will just work. I have used both JHEMCU and GEPRC flight controllers and, so far, have NOT had any issues. In fact, I had a GHF411 board in my 4 inch Katana-LR4 build running 1504.5 motors with absolutely NO problems. 

Did I mention that I crash a lot. For me, a good landing is one where nothing got broken and I don't have to walk to far to get the quad. I did hit a steel light pole once with my Phantom-3A; damaged the frame and cracked the lens on the camera. The flight controller {a GEPRC GEP-12A F4 AIO whoop board} did not get damaged. 

In fact, the GEPRC F4 v1.2 12A AIO board has the USB connector pointing DOWN and has motor connectors, just like a lot of other whoop FC boards that are designed for the plastic "whoop" frames. 

In fact, I would recommend either of these GEPRC boards; 
depends on how you feel about the USB connector and whether or not you want the VTX.
If you want to use your VTX, then the GEPRC F4 v1.2 12A board should be fine.

i had generaly good experience with happymodel electronics. the old 16x16 2s stack is rock solid and i hadnt any issue by the crazybee board from the larva.

i dont know a jhemcu board which would match nicely with the larva settup? 20a aio is overkill..
i guess the geprc iflyrotors could be a good choice.
