Default RE: Video at Youtube - Patriot at 168 mph from méxico!! plane belong to our friend Hector...

I have clocked many airplanes on radar myself. Not sure how many but prolly over 3 digits. I have spent hours watching/clocking plane after plane cruise between 150-300mph (dynamic soarings). I have also clocked many a jet at jet rally's, fast guys at the field, and Q-500 and Q40 contests. From my impression that patriot was doing some pretty big monster dives and then leveling off. Also keep in mind he is at 3000 feet as well. 168 did not seem unreasonable at all based on what I saw in the video. If I had to do a visual analysis with no speed given I would say over 150 for sure. It is not usual to clock dive passes way in excess of prop pitch speed. For example I had a plane that did a very consistant 152-155 level but out of a big dive I saw over 170. There are no brakes that come on when a plane exceeds prop pitch speed just some extra drag. I'm surprised the Bushnell gun picked him up at all as those guns are generally horrible at clocking small objects at high speed. You would be surprised how much speed you can build in a dive with a decently slipery model and some weight.
