That’s simply the reality of dealing with prototype aircraft, and it’s far from the only one. Even well-known, production aircraft see plenty of disagreements on their performance, even between real pilots that flew them at the same time.
For example, you can find two german pilots, who fought in the battle of britain, one claiming they could outturn spitfires in their 109s and the saying they could not. Both pilots have several air victories to their name.
Who do you believe?
The Type 5 cannons had already been fitted to aircraft capable of reaching the Kikka’s typical speeds (in a dive) and worked fine. I doubt they’d face insurmountable problems with them.
It’s not that they “couldn’t”, they never intended to retract the gear in the very first flight at all. If you read the whole sentence it claims exactly this.
“…the landing gear was not to be retracted for the initial flights”
This is VERY common when testing new aircraft.
And we don’t know if the 38MT was even built at all, much less to a state where it could be launched from an aircraft.
Huge difference.
Again, completely different topic since we know the US 90mm guns actually existed.
This would only be comparable to the Kikka if there was evidence the 38MT was launched from an aircraft and guided itself at a target, and we simply didn’t know what its performance was.
They aren’t similar at all. For one, the 262 is much heavier and has swept wings; Kikka has straight wings and is almost half the weight empty.
You’d be surprised at how little data we have for most production aircraft in the game.
Unlike the 38MT, the T95E1 actually existed too.
Which is none because the 38MT is the fakest of them all.
