Hello. I'm looking for speed at different altitudes data for the Ki-48, preferably the Ki-48-II. I haven't been able to turn up anything, and I don't know where else to look, so I figured I'd ask here. Thanks.
Warbird Performance Blog also has performance data for the Ki-48 which I would consider more reliable than the TAIC reports since it's owner uses original japanese documentation, and that the TAIC reports are more performances estimations than actual flight data.
