I agree with PA BEN.
Those cheap arfs are
- looks great !
- good build quality
- very affordable
BUT their flight characteristic sucks.
In other words, they never do research and development of their airplane.

Some people may say they had a good experience with these kinda ARFs
but it's either they have low expectation or lucky.

If you want to do arf, go for Hangar9, Great Planes, World Models or other name brands.

I stopped buying cheap ARFs.
