I dunno, we could try a doppler test on those two high speed passes.

It looked faster than 70MPH to me though.

My XPD-8 with the upgraded motor setup, clocks in at 83MPH on a similiar pass, and it doesn't appear to be faster than that the DF-32.

Going by my XPD-8 I'd put the DF-32 in that video close to 100mph.

Of course the pilot did decending full speed passes, and you may be talking about straight and level transitions to full speed, where it may not reach the same speeds.
