    He had PLENTY of airspeed....it was flying. Came off the ground very nice............He had the "rons" reversed!

    Don't try to over explain this one..........[>:]

    Came off the ground nice? I don't think so.

    It was stalling as soon as it was bungied in to the air. Looked heavy and underpowered.

    RE: hawk take off crash (edf)

    it was never flying, the moment it took off it was stalling, he had enough airspeed to rotate the aircraft but not enough to fly it

    Ha,I don't think you could have done any better imo. It was doomed no matter who flew it, it lacked power,too tail heavy after adding weight to balance.

    Excuses, Excuses, Excuses......"tail heavy..underpowered" blah blah blah.

    The pilot's inexperience is the fault of this crash. I still say the Rons were reversed, and also...you did not have any Expo dialed into the control, which caused this low time pilot to over correct everything, because it was too sensitive!!!

    You guys should stick to high wing trainers!!

    RE: hawk take off crash (edf)

    I have seen many planes that had the ailerons reversed. When the ailerons are reversed, generally it rolls in one direction, then it rolls more in the same direction until the ground takes over. The controls were probably too fast. It seems to be way underpowered, but that is a characteristic of an EDF at low speed. You have to learn to deal with that. All of the control inputs, including up elevator, causes more drag which slows, or stops, the needed acceleration. It should have been kept about one foot off the ground until a much higher air speed was reached. The EDF will NOT accelerate quickly, like a propeller plane.

    Ha,

    Sorry, you wrong about the rons, you are wrong about the pilot and perhaps wrong about expo.
    One thing you have failed to overlook is the owner/builder, who was not the pilot for the maiden. I was video.
    Apparently 6s instead of 10s was used. It was also tail heavy as well as underpowered.
    Don't give up the day job for air accident investigation.

    It's funny cause I don't remember saying that I could
    Doesn't change the fact that pilot error is usually ALWAYS the cause of most crashes no matter the Excuse.

    Usually and always have conflicting meanings, the common phrase usually always is an oxymoron

    6S instead of 10s is a set up issue, which is pilot error.

    Ha, you comical duo crack me up.

    I suppose on reflection the pilot is ultimately responsible but alas he was assured by the constructor of this fine looking aircraft that she was correctly fitted out and ready for maiden.

    Naturally the pilot would check correct control surface movements and if necessary introduce personal touches such as expo but I'm not sure if its the pilots duty to ask the constructor to go back home, bring the manual,to verify that the right amount of cells had been fitted when the word of the constructor was she was good to go. There is an element of trust I believe that still exists between modellers.

    On the bright side you guys get to practice your judgemental air accident investigation visual skills and hopefully whilst at it enjoy some eye candy crash action.

    All the best, respect

    Odd that none of you have noticed that the EDF sucked in some trash and was FODED. You can hear the motor/fan screaling a moment before it came off the bungie. It was underpowered because the fan was jammed. The rest is the resultant "pilot error" based on the asumption he still had thrust to fly.

    I'll agree that maybe the ailerons were a bit too high on high rate for a first flight being a contributing factor, but what you see is just a classic power off stall too low to the ground.

    I was wondering if I was the only one to hear that. I don't fly EDF but guys at my field do and any time I've heard that sound it means things are about to get interesting.
    For a kit you are, and to a kit you shall return.
