LtThunderpocket,
The answers, serious ones, are simple. If HiTech gets wind and has time to reply, the simple answer is...again...all we need is time and money. Both are finite when it comes to development and hiring new designers. His staff does all of that plus monitor arenas, these boards, handle and research technical issues.....try reading the bug report or Technical forums too. That will give you a real feel for what all the fine folks at HTC are doing on a daily basis. It's more than 40 hours a week, I can assure you. When I started, it was $30 a month and had maybe 6 or 8 planes and an M3
It was a mature crowd back then. (agewise)
Here is my suggestion to you: Pick a favorite plane you want to see added and post about it, do some research...is it allied, axis? What period...when first used.... let's give HTC a simple task. One at a time.
You can do a search in this forum and may find many already requested. See what was stated. I am going to post 2 older ones and see if I can get a bite (byte)
