"2,500ft all they way up through 15,000 ft" If you are willing to look past at least 8,000 feet pressure altitude discrepancy, then yes everything is ok. I tested at 23,000 with 50% fuel, full blower, 2700 rpm all cooling flaps closed, mixture rich, and maxed out at 243kias which translates to about 402mph true. Not bad, but not correct either. Those results were achieved with a dive from 24k to 23k, then waiting until the speed stops decaying. It's even worse with a level acceleration coming in at around 236kias. At sea level with a dive I can get about 289kias which is about 332mph true. With about 275kias achievable in level acceleration. Aside from the OPs hyperbolic post, no one is saying it's off by a huge amount. But it's missing 5-10% of top speed as a rough estimate. Well, I am not looking past 8000ft PA discrepancy, nor I am saying the flight model is correct. I did actually say it does need work. My point was, if people complain about the speed while not realising we are talking about different speeds (indicated vs true) and different units (knots vs mph), it just creates a lot of confusion. First message in this thread: ”this thing barley does over 200 mph, even stripped down with no fuel..” it is simply not true. This thing actually does well over 200mph even at full load. If we wanna talk about that 5-10% difference and other oddities in this module I am open to it, it definitely needs work and tuning; however let’s not spread wrong and misleading info.
