    Viking Dragonfly MKII "Quick Build" - SOLD

    It is sold. I said this in the post right above yours.

    I've built a couple of fun electric airplanes, happy to answer questions.

    Very true, but by the looks of the “helicopter” in the video, I doubt it’s getting anywhere close to that speed.

    “Powered autorotation”? As a helicopter guy, I am pretty interested in what you mean by this. On a coax you certainly don’t want only one rotor powered if the motor fails on the other. If there is a drivetrain that couples both motors so that one can drive both rotors, then it would work, but it...

    Filing/flying IFR in a VFR only airplane?

    If you don’t mind 3500’/4500’ you don’t even have to worry about the “dreaded remain clear of Class Bravo” because you don’t even need a Bravo clearance for the SFRA. If you are already South or LAX then just remain below the B shelf and step your way up as you head South. When coming in to...

    Filing/flying IFR in a VFR only airplane?

    I agree with Marc on this. I fly out of San Diego and often fly North through LA. There are plenty of VFR options that will be easier and probably quicker than IFR anyhow. Look at an LAX TAC and study the VFR routes on the left side. I fly IFR for work, but have no problem getting through LAX...

    Insurance?

    You either need to hire a financial advisor, or fire your current one. S&P went from a high of about $1550 down to about $750 after the Great Recession. It is now trading at $3500. Recovery from past damage? Hahaha. It recovered by early 2013, and then nearly doubled from the high pre 2008 crash...

    Good numbers ?

    I guess those specs weren’t as good as the C-130, at least not in the eyes of the Air Force.

    New EAA Chapter Build Project SoCal

    Doran, I agree with everything you said. I’m not saying not to give rides. I’m just saying that turning out these 10 minute young eagles flights just to pump up the EAA numbers isn’t the best way to do it. What is much more helpful, in my opinion, would be taking passengers with you during the...

    New EAA Chapter Build Project SoCal

    Mr. Ryan, when I came to your chapter, as a very active experimental aIrplane builder and flyer, I was looking for hangar space. I had a flying experimental I built and another I was in the process of building. You had no hangar space available because there were nothing but rusty dusty...

    New EAA Chapter Build Project SoCal

    Where are you located? I’ll happily stop by if I can gain more value in doing so than something else I could be doing with my time. EAA caters to young kids and retired people, but forgets about the 40 years in between. I understand the marginal benefit of young Eagles and pancake breakfasts...

    New EAA Chapter Build Project SoCal

    I understand that EAA is being treated like a social club for the older members. But younger members have enough social clubs on their phones alone (I am not one of them, I am social media free). An EAA chapter that is just a social club isn’t going to attract young pilots. Young pilots want to...

    New EAA Chapter Build Project SoCal

    My opinion might not be favorable, but I don’t think Young Eagles is really having any effect. First, the kids flying young eagles flights are already interested in aviation. Also, they are a long ways from being pilots. What EAA needs to focus on is young active pilots. All EAA chapters ever do...

    New EAA Chapter Build Project SoCal

    Finally, an EAA chapter actually doing something besides a pancake breakfast! I wish the chapters down here had that kind of activity.

    Intake Design Change Results

    I certainly don’t see what the downside could be besides the cost. I guess it depends how important even mixture distribution is to you. You can always fly it with the stock intake manifold and see how it does for you. What aircraft are you putting the Corvair in. The intake manifolds are...

    Intake Design Change Results

    So just how well can a Corvair run with the stock heads and intake logs? Here are some results from yesterday's testing. This is a screenshot of my EIS data. The red cells are when each cylinder first peaks. Notice how tightly together these are, indicating very good mixture distribution. The...

    Intake Design Change Results

    Dale, although the extent of my mixture discrepancy is more severe than most, the uneven distribution is definitely not a "one off situation". This intake manifold causes the even bank to run rich. Your even bank runs richer than your odd bank. The builder of this intake manifold told me that...

    Intake Design Change Results

    Sorry to bring up an old thread, but I feel like I should close the loop on this and answer the questions that never got answered. Also, this problem not only kept me in phase 1 for an entire year, but shook my confidence so much that I never really enjoyed flying the airplane until recently. It...

    Viking Dragonfly MKII "Quick Build" - SOLD

    Hey guys, my Dragonfly project sold a few months ago to a gentleman in Texas who had plans and was looking to build one. This gave him a considerable head start. I hope he gets that beautiful plane in the air someday soon!

    Repairing Small Ding in Engine Mount

    BBerson- excellent point. I too am worried that a weld or patch might concentrate the stress and cause a crack. I will measure and evaluate a blending solution.

    Repairing Small Ding in Engine Mount

    Thanks for all of the advice everyone. To answer some questions, this is a Corvair engine mount for a Sonex. Mad MAC, I don't really understand everything you said. What exactly is a 20 to 1 blendout? It is definitely not a crack, and I don't think stop-drilling is the correct procedure. I...
