    Raptor Composite Aircraft

    I don't think they have one.

    Raptor Composite Aircraft

    Then maybe that was the problem.

    Raptor Composite Aircraft

    They don't cut the bed in half. They move it one piece.

    Raptor Composite Aircraft

    I nailed it. @2:00 "With an 8,000 foot runway, that is actually enough runway that you could bring the A/C into ground effect and fly for about 3,000 feet before having to put it down again." @ 3:20 "Well, that doesn't prove that the A/C is stable in pitch. That doesn't show me how much...

    Raptor Composite Aircraft

    Because he made decisions that the "experts" here didn't agree with ? Because he disobeyed some of the "rules" ? I don't agree with a lot of what Peter has done. But that doesn't mean I'm right and he is wrong. This story isn't done yet. There are no points for being a critic. Anyone can...

    Raptor Composite Aircraft

    I don't know how he is going to pay for the move or the rest of the flight test program for that matter. I am not his book keeper. What I do know is that Peter hasn't quit and doesn't look like he is going to quit anytime soon. He has a lot of followers and supporters. I'm sure he'll figure...

    Raptor Composite Aircraft

    It isn't the end of the world to move it. The way some of you talk it is like mission impossible to move it. Peter designed it with removable wings. Once the wings are removed, it can easily be lifted by a tele handler, crane or hoist onto a trailer. The load will be over width, but not over...

    Raptor Composite Aircraft

    Over width stuff gets hauled all the time. The whole plane isn't over width, just the wing stubs. That makes it a lot easier. I see no problem loading that plane and its wings onto a trailer and hauling it wherever it needs to go. I'm guessing it can be trucked for about $3/mile.

    Raptor Composite Aircraft

    They have the cradle (mold) for the hull. Should be able to set it in/on that on a trailer.

    Raptor Composite Aircraft

    Was the Raptor designed to be taken apart ? I seem to remember some bolts securing the the main spar that goes through the cabin to the wing spars.

    Raptor Composite Aircraft

    First off, as far as I know, this is the first time Elliot and Justin have brought the PA. So if having the PA on site for the test flight (using it as the chase airplane) was, indeed, a requirement, then there was zero chance of getting airborne on the first two visits. Ouch. That is a bit...

    Raptor Composite Aircraft

    I haven't looked closely at the redrive, but it seems to be based on Gates blower belts. Blowers take a tremendous amount of power to drive. What is wrong with the redrive on the Raptor ?

    Raptor Composite Aircraft

    You built and flew the 1/4 scale model for Peter ? I have a question about the final weight. There seemed to be a lot of CAD and design done and yet the final weight was way higher than anticipated. How did that happen ? Were the composite pieced heavier than planned ? Were allowances...

    Raptor Composite Aircraft

    NASA doesn't agree with you. For a comparable thrust to weight ratio... Real airplane = 340HP ish. Real airplane weight = 3100 lbs. Real airplane power/weight ratio = 0.11 HP per pound. Model 50 pounds x 0.11 HP/lb = 5.5 HP or 4,000 watts. Certainly doable with today's electric RC motors.

    Raptor Composite Aircraft

    The Raptor will weigh about 3200 pounds ready to fly. The model was 1/4 scale. It would have to weigh 50 pounds in order to be a valid representation of the real plane. Something tells me the model weighs no where near that.

    Raptor Composite Aircraft

    I think he says it's 3" at a 10 degree body AOA. But I think they need 6 degrees of body AOA to get lift. Seems like a narrow margin?
  17. U

    Raptor Composite Aircraft

    Is a test pilot really going to just taxi this thing for a while and then fly it? What if it goes into a death spin? Peter has a 1/4 scale model. Wouldn't that provide some good flight characteristic information prior to someone flying the real thing? Or are models over rated?

    Raptor Composite Aircraft

    That is the video that speaks about prop clearance. Nobody has commented on it. Do you think there is enough prop clearance?

    Raptor Composite Aircraft

    I just reread the last several months of comments in this thread. The spreadsheet was in a video from last week and no one addressed these matters. Are Peter's lift off projections correct? Seems the main wing might stall before the canard? Or at least the canard wants to fly well before...
