Hi,
Are You converting an existing glow powered F3A machine to electric? If Yes - what model?
Or is it a new full 2 x 2M F3A electric powered machine You want?
Or could a plane like Sebart MythoS 125E work also?

There is also a full 2 x 2M MythosS Pro avaliable here in Europe now but I do not know when it will arrive in US.
For example from this company

ExtremeFlight 2M Vanquish is a rather popular F3A machine that is not so expensive.

Just check threads on above planes to see what motors, ESC and suitable LiPo is used.
