Daily plane posting limits have never been a problem for me. I have some reasons for this. And I'm not going to mindlessly repeat the word "quality" like any other cliche.

Reason 1

I'll just say "quality" one time. I'm not going to lie and say that I put a ton of detail in my planes, or that I have better quality than other players, because I don't. However I will just point out one thing. When my build quality rose (after I created the cornerstone build of my building style, the SPE Mastodon), the recognition that I got skyrocketed.

Reason 2

School is unfortunately life for me. I'm in highschool, and I want some career that will require some pretty intense education. I have time, but I don't have tons of time. Each plane of mine takes about 3 hours to make. I don't have time to reach the daily posting limit. Sometimes I cannot make a plane every day. After all, I am a person, not a factory.

Reason 3 - This is the important one

You might've heard people talking about posting at the right time. For me, that time is a window of 3-5:30 PM. I usually can only post one build in that time window. In my eyes, a build posted in a time that is not in that window will not get as much recognition as it could potentially get.

To un-confuse you about this I'll say this. Unless if you want to spam all of your builds in the very short amount of time that is optimal for posting, you will have to wait until another day to post all of your planes.

These are mostly my feelings, and they might not help you at all. I am scatterbrained at the moment, so you might just be confused. If you need clarification, please ask for some in the comments.

Thanks.
