    “Had alot of people stop to watch it”
    Took about two hours build. Flew it for about an hour.... Dave your design rocks!!! On the maiden flight, I never had to adjust anything. Through it up and flew it. I did not want to stop flying it. After about an hour of flying, this plane sure had alot of people slow down and/or stop to watch it. Somebody actually got out of their vehicle to hold it. Very nice work, Dave!!!

    “The most eye catching”
    By far the most eye catching of the models....F117 was what brought me to the RC Powers in the first place. Dave and Scott's dedication and communication on the forums, and the environment of help/knowledge from everyone else is what keeps me here. Great job guys.

    I am overwhelmed, these planes are just simply fantastic!!

    Quick question regarding the vertical stabilizers. Are they 'toed out'? I cant tell for sure but they look so.

    'Toe Out' means the stabilizer's Leading edge is farther out than it's Trailing Edge. 'Toe out' of a V Tail stabilizer allows the airflow to hit more of the topside(makes the topside windward) and creates a nose up trim that acts as 'decalage' needed for a forward CG, allowing the elevons to remain more inline with the wing and increase lift as well as reduce drag!

    An easier option could be to split and rejoin the rudders so that the upper part out of the prop wash are turned inward(nose up) slightly. That way the amount of 'decalage' effect will not vary with power setting.

    If you could, send me a screenshot of your print settings and take some pictures of the pages as they are printed. Then shoot me an e-mail: [email protected] We'll get it sorted out for you. :)

    There is no "toe out" built into the stabilizers, they are meant to be mounted straight.

    We wouldn't toe out the v-tails on this one because of the thrust vectoring. Anything behind the prop should be straight and level unless a servo is moving it.

    4 hrs flat. The build was super easy, and even though my garage/work shop was about 94 degrees, I kept my wits and everything fell into place. Pictures 13,14, 15 I think? in the instructions confused me so I checked the assembly blow up and it was clear. No vtails for now. I used MPF for the first time, with foam tac, and I am impressed. However, I would recommend cf reinforcement of the tail section for anything other than depron as you may see in pics, I reinforced with 3m extreme tape. 19 oz with mjv3 and 1600 3s. Plenty of power. I used the mjv3 with the v2 and was happy. This should be just fine thrust wise, and the flight time will be excellent. Motor mount area is nice and sturdy. Anyone familiar with the fuselage flex on the v2? No more on the v3! Maiden tomorrow, then paint.

    Wow Greg! You are a machine!

    Yeah I was looking at the instructions myself and they look incorrect. The following steps look wrong:
    Step 14 - 15 and Steps 19 - 22
    They don't match up to the actual parts on the Untiled Assembly.

    Also the plan view says you need 6 servos when it should say you need 4.

    Wow that was fast!

    You caught that huh, the build steps in the middle.
    Enjoy those while they last, that was actually a prototype that ended up being cut at the last few weeks. It had this sweet hand-grip that doubled as super air intakes but the problem was you just couldn't get the battery up far enough.... so we changed it to what you have no and were very happy we did. You can kind of see it in the video shots if you look close too.

    Anyway, updating those steps is on the list, don't worry.

    And again, great build and so fast!

    I'm having some trouble viewing the video. It's good for the first minute or so and then it keeps stopping on its own. Stops in the same place on my iMac desktop and on my phone. Not sure if this is user error, but I thought I'd mention it in case it's a bug.

    Dan, when I downloaded the v2 I received a nice email room Scott saying that I was the first to download, and I made it my mission to be the first to fly. Just wanted to carry on the f117 tradition! I built 3 of them so this went together very easily. This whole plane, Btw, was cut from one sheet of MPF. I cut a piece out, then squished the remaining pieces closer together to minimize waste. Depron sheets are a few square inches less than MPF, so it may not apply for depron. Lipos are charging....
