25.5mm 25A GHF405AIO - you wont get anything near this price

I have 3 of these 35A version. 4 UART. I like the pad positions. There is no Blackbox :/

20mm 35A GHF420AIO
https://www.aliexpress.com/item/1005003752917857.html
9V and 4 UART. Excellent for low-profile 4"/5" ultralight, with DJI AIR.

Recent Shenzen shutdown and all the 5th circle of Dante's hell stuff going on, this might be only chance to get decent FC before summer.

I have the 20mm 35A GHF420AIO in my FrankenFly-2-4 build since the Armattan Gecko 4 inch frame
didn't have 26x26 whoop mounting option... seems like a good board to me. 

CycloneFPV has the JHEMCU 20A GHF420AIO and the JHEMCU GHF405AIO 25A for $ 49.99 USD.
They also have the F411 processor boards, however, I have moved up to more powerful FC boards. 


Also, I just picked up 2 JHEMCU GH743AIO 3-6S 40A FCs for $ 79.99 each which I thought was a pretty
good deal for this caliber of board...at CycloneFPV. Just picked up a couple to have in the parts bin. These
boards can go in virtually ANY of my builds regardless of size. 

I have only purchased from CycloneFPV a few times, but have been pleased and had NO issues.

I really hate F411.

F405 has double flash space of F411 and F722. and 168Mhz handles 8K and can be bumped up to 200Mhz

And both boards I linked have 4 full UART.
Seems pretty future proof to me.

Hi Roman,

Well, I can't say that I hate an F411 if it is going in a small whoop or toothpick;
something that won't need a GPS unit. On the other hand, I have moved on
from them a LONG time ago.

FYI: The JHEMCU GHF420 has an F405 processor.

One of the FC boards that I have used a lot and really like is the HIFIONRC F7 AIO 
25A or 35A although I generally buy the higher rated board when it is available.

Remember I made an ESC tutorial how to fix JHEMCU GHF411 and HifionRC F7.

Im a bulk buyer - The companies should be sending me samples to review

Hi Roman,

I had NOT seen your repair guide. I just took a look at it. EXCELLENT !!

I'll have to check that out, I recently lost one of my ESC's on my Hifionrc 25a. Well, I -think- it's an ESC, I tried a few different motors but no bueno. Shame, I really liked that board, super easy to solder, and more uarts than I'd know what to do with.

Got a link to that tutorial?
