I haven't seen a thread on this one yet, so here we go.                                                              Last Post
Whatever one might think about iFlight, this board looks very interesting.

WOW, truly a board that could be used in almost anything; it is almost a "UNIVERSAL"  board that could be mounted into just about any build from a tiny whoop, a toothpick, a 4 inch, a 5 inch, to maybe even a light weight 7 inch   

Yeah, DJI plug and play socket as well. What more could you ask for?

I will have to get one.


KababFPV's review:  A Whoop board for FULL 5"?

There's another thread about the new iFlight F7 and H7 AIO flight controllers here...

https://intofpv.com/t-iflight-f7-h7-aio-...ontrollers

I haven't watched Bob's review but as it's an iFlight manufactured FC costing either $70 or $90 respectively, that's a lot of money to give to a company who have a history of design and QC issues with their flight electronics. Roll the dice and take your chances 

So, should I delete this thread? Although that thread is more general and this one specific.

No. I don't see any point in deleting threads. The other one was just announcement of the boards when they first surfaced a few months ago. We already have multiple threads on here for the same things anyway. There is no rule prohibiting that.

This forum isn't RCG where they have ONE thread for each product which then runs into hundreds of pages over many years  That just makes following the thread and finding any relevant information about the product virtually impossible. Lots of smaller discussion threads are far more user friendly where appropriate.

the iflight aio wont fit in a traditional whoopframe and wont fit in many microframes, the outside diameters of the board dont match these frames. 8.8g is to heavy for micros smaller than 3inch props.

Hi Hugnosed,

Very interesting.  Now, realistically it is better suited for the 4 inch and bigger builds. After all, who needs 55A in a whoop, right? But, it is still intriguing. Imagine just having to tool your manufacturing for the 26x26 {nominal} mount format, then assemble a variety of AIO boards.

I am ordering one of these today. When it arrives, I will check all of the frames that I have including all whoop frames just to see what and how it might fit. I will likely use it in either a 5 inch or 7 inch build. In fact, this looks like a great board for my Megabat 7 inch build which has diagonal mounting for the FC. Put a set of those T-motor Trick 2306 2400 kv motors on it with 7 inch props and see what happens.

I have just ordered the new iFlight BEAST H7 55A AIO {26x26} FC.  

That's a lot of money for an FC. I hope you rolled two sixes

Hi Snow,

Yeah, I know. It is a gamble. But, hey, I'll be the guinea pig. Whether it works out or not, everyone else will know my first hand results. Although I intend to use the JHEMCU GHF420AIO-35A in the Katarms-LR7x build, that board might be right on the border since I am not sure what the amp draw will be with the T-Motor Trick 2306 2400kv motors.  I was also looking for a high power board to use with the Megabat 7 frame which only has diagonal mounting. 

Thanks for being concerned. 

Although I hadn't thought much about the cost of a 55 or 60 amp flight system {either an AIO or a stack} of any size, I have now been doing some research and checking things out. First, we need a full flight system; that is flight controller and ESC package whether it is in an AIO single board or a stack, but must include the ESCs. Now, let's limit the price to $100 just to keep things in perspective. Next, it must be rated for 55 amps or more. For the moment, we will not consider the mounting format or physical size. Now, let's go research.

For this research, I used my top three suppliers: PyroDrone, RaceDayQuads (RDQ), and GetFPV. This endeavor has been very interesting. Everything with an amp rating of 55 or higher has a 30x30 mounting except for one; the SkyStars F7 HD 20x20 55A AIO. Also, I could find only 3 {HIFIONRC and SkyStars} with a cost less than the $89.99 price of the iFlight BEAST. Furthermore, most of the FC systems with ratings this high are more than $100.

What I found just as interesting, if not more so, was the number of FC AIO and stacks with lesser amp ratings and prices in this same range and many over $100. Even FC packages with 35-45 amp ratings approach this target price range.

Now, one could argue that the quality or durability may not be equivalent from different manufacturers, however, I have seen some interesting failures of supposedly high quality products. Regardless of brand, consider that all of these things are made in China. Consequently, I reserve my opinion for each item on its own merit or shortcoming. On the other hand, I generally stay away from specific items with known issues rather than the brand or company; it depends on if the issues are across the board with everything or only particular items.

To summarize:

Is the $89.00 price of the iFlight BEAST 55A 26x26 AIO high. Well, YES.
On the other hand, it is quite in line with other 55-60A flight control systems.
So, overall, I think the price is ok.
If the item works anywhere close to the specifications and doesn't have any quality issues,
then I will be very pleased and might consider it for other builds as well. 

The following is a list of FC systems meeting my search criteria:

HIFIONRC F7 60A 30x30 stack for DJI:  $65.99
HIFIONRC F7 60A 30x30 stack:  $69.90
SkyStars F7 HD 20X20 55A: $78.99
HOBBY WING 60A (30x30?) STACK {on SALE}:  $79.99
JHEMCU 55A 30x30 stack: $79.99
HGLRC Zeus F760 60A 30x30 stack: $89.99
Zeez F7 60A 30x30 stack: $94.99
Diatone Mamba F722S 60A 30x30 stack:  $99.99

Those board look like 34x34mm. (with holes at 26mm). Should fit anything >100mm frame.

A tiny 75mm whoop would not use a $100 FC.

You guys have to realize iFlight took big risk making this product. Very unlikely to make money. Its first FC to use BGA F7 and H7.. hopefully more AIO 26mm will do this to save space. Since 2017 STM32 options for 10x10 and even 7x7mm WCSP packaging

It f'd up how cheapo this hobby is. It costs under $15 to make a F7 FC. But not just because cheap parts, but also cheap manufacturing and QC tooling.

Also helps to know pro/cons:

Speed
F3 - 72Mhz - only 256K flash.. can run new Betaflight
F411 - 96Mhz - can run 4K PID with RPM filters
F405 - 168Mhz
F7 - 216Mhz (less power and faster M7F core) - run 8K PID
H7 - 480Mhz M7F core 40nm. 2MB flash. Future proof

UART.
F411 boards typically only have 2 UART. Rarely 3.
F405 and F7 have 6 UART - but some boards only expose 3.

Inverted
F7 automagic can invert anything.

So basically, F7 already handles everything. What about 32K PID loop?

Human stick control happens within 50Hz. Propwash is 50-150hz. Motor noise is typically 200-600hz. So 8K and 4K more than enough.

32K doesnt help with response delay (stick feel). 10ms+ camera vtx delay. 10ms+ goggles delay. 20ms for you to visually process. 20ms RC command to receiver.

Only then, rc filter, gyro filter, dterm filter.. which need to be fast to avoid phase delay, but Mhz doesnt help here..

The BEAST has arrived. I received it on 2020-12-04. SWEET 

As indicated, the BEAST has a 26x26 whoop mounting format and will, in fact, fit tiny whoop frames. I have shown it pictured on top of an 85mm frame and it fits very nicely on that frame. {since there are no whoop notches, it doesn't slide down between the ducts on 65mm frames, but it will mount}. The BEAST is the same size as the other 26x26 whoop boards. I have attached a picture showing the size comparison between this board, the JHEMCU GHF411, and the JHEMCU GHF420 {this one is a 20x20 AIO}.

Now, I wouldn't put this board in a whoop frame, but it will work. 

The BEAST has Betaflight 4.3.0 on it. When I connected it to the Betaflight Configurator, I get a Warning message that the version is newer than the configurator, but I could find any new version. Now isn't that interesting. 
Presumably, the 10.7.0 version will work. This is the NEWEST  version that I could find.

Betaflight shows 8 UARTS, but I could only find pads for 1, 4, and 7 plus 2 is inside the DJI connector. That is enough for the GPS, so I am good with that. 

While in the Betaflight Configurator, I saved an assortment of configuration files using the CLI; these are attached.

The BEAST will go in my next build, the Megabat-7X, with the 2306 2400kv motors. 


This board was purchased from Tiny's LEDs, but both versions are SOLD OUT already. 
So far as I can tell, it is still available at PyroDrone (HERE).

Maybe I should order another one 

I'm working on a build for this and designed a mount that might help others here
