I have just bought a radiolink F722 FC for my fixed wing aircraft. But I can’t find the firmware for flashing it into ardupilot software.
There is firmware for Radiolink F405 FC . Is both are same ? Help me out!
It’s my understanding that the F722 chip doesn’t have enough memory for ArduPilot. I personally avoid F722 FCs myself.
How much space is required for storing ardupilot firmware?
Needs 1mb flash. Use search on the forum for other futile posts about Ardupilot on an F722

I try to point this problem out whenever I see a YouTube review for a F722 flight controller. A lot of people find out about this limitation after they have purchased a F722 FC. I personally wish I had known about this limitation sooner. I wouldn’t have purchased as many F722 flight controllers in the past had I known they couldn’t be used for ArduPilot.
I bet I’m not the only one who thought a F722 chip was better than a F705 chip in flight controller applications. In hindsight I can see this was a naive assuption.
1mb is the bare minimum.
For using all features, 2mb or more is recommended as 1mb builds lack a lot of features. You also need a powerful processor with enough RAM if you want to do the more ‘advanced’ things, like Lua, On-board FFT, etc.
Also, Radiolink violates GPLv3 consistently, so we couldn’t help with firmware even if it were possible.

Am I correct in assuming I should avoid Radiolink gear (for ArduPilot purposes)?
Am I also correct in assuming the H743 chip is a good option for most ArduPilot flight controllers? I’ve purchased multiple Mateksys H743 flight controllers of various flavors (Wing, slim, etc..). Are there better options at a similar price point?
Yes, avoid Radiolink.
The H743 and H757 are both very viable and support all major, recent features. Matek has an attractive price point, along with the other usual Chinese suppliers. If you want other than Chinese hardware, CubePilot, 3DR/mRo, TBS, and Ark all make good hardware, but the price points are considerably higher.
In general, look for a supported H7 board with the features you want (number and type of outputs, connection style, IMU isolation/heating, etc) and shop price second. Specific manufacturer is about the last to consider unless you have import restrictions to abide.

I wouldn’t say better but the TBS Lucid H7 is a good option. There is a Wing version also. I have a bunch of Matek boards and I’m impressed with the TBS board so far.
