    twin boom pusher plans

    Re: twin boom pusher plans- ION Greetings, I haven't talked with Steve for a while now. Last time I was at Janefield we were discussing a re-do of the engine cowling, and a new vendor for the nose gear. Sounds like he has the main gear sourced, the avionics, motor and prop pretty well dialed...

    Caveats of high lift airfoil

    The sparse reading on WIGs I recall tended to place the Horizontal Stab rather high to keep it OUT of the ground effect, supposedly to improve its effectiveness, the operating theory (Yeah, mechanics illustrated I think) was that if the craft rose to high, and left ground effect, the main wing...

    Whole wing as an aileron ?

    Dan, I won't pretend to be able to prove this, but is not drag due to lift a function of airfoil shape as well? I recall stories by fighter pilots relating the how the F4 Phantom would shed a lot of speed in a high G turn compared to a more modern F16. Yeah, that is pretty anecdotal for...

    twin boom pusher plans

    Legitimate points Topaz, I will see if I can entice Steve to read this thread and contribute, but I doubt he has much spare time. Having sat in the Ion several times, only once when everything was attached, I can say that it feels good, really puts a grin on your face. I could just imagine...

    twin boom pusher plans

    Greetings, The Ion seems to meet a lot of the original goals stated. Some posts indicate concerns about Ion Aircraft's lack of updates on the website, engine changes, wing changes etc. and importantly the question of whether it is still an active work in progress. So, having Steve's number on...

    Vtol design: 1 vs 6 engines

    My experience with helicopters is pretty thin, but I recall my pilot saying that the power setting for hover/take off was the same as level flight cruise. For us, hovering was being just high enough to see over the trees or intervening hill so I could spot for the artillery. It was a blast...

    Got screwed today

    The membership of this board includes many aviation disciplines, I would think that there might be one or two in the legal profession that could pipe in. If not, I know that there are several on another board I visit, ipilot.com. One in particular is named Cary. They have a "legal" section on...

    Got screwed today

    Ok, if you believe they knew, and sold it to you anyway, and managed to, shall we say, encourage you to be quiet, what happens when they do it to someone else who ends up dead as a result, will you feel as though you should have done something different then? I fully sympathize with your...

    Lightning Aircraft?

    Re: Berkut rework?? Hello Bill, Did I read you right about reworking the Berkut?!?!? It seems to me they pulled the plug on it a while back, and the website suggested a dim future for returning to production. Does this mean that they have found funding to make a go of it again? I hope so; I...

    Homebuilt metal forming tools

    Used tools. Jake, There are a number of used tool re-sellers and consignment houses around. Here in the Minneapolis area there are at least 4 that are worth spending the day at. The one I go to the most is called Tried and True Tools in Blaine MN. As for looking, you could start with a...

    Homebuilt metal forming tools

    Once you go industrial, you'll never go back Something I have found when shopping for tools/equipment is that the offerings one finds through sources like Home Depot, Menards, Lowes, Sears, etc range in quality and suitability from "you have got to be kidding" to just serviceable for consumer...

    Homebuilt metal forming tools

    Wood tools in aluminum. Regarding the comment that most any wood tool will work in aluminum. This is kinda-sorta true. Basically the key is to use a sharp tools, good work holding techniques, and careful feeds. I machine aluminum with my router often, however, my router weighs in at...

    Low Drag Prototype Car

    EVs Hello Mighty Mira I am intriged by your project. I have a 60 mile round trip commute myself, and the cost of either gas or diesel is sorta like a shop vac reaching into my wallet, it sucks. My research into EVs is focusing on storage (batteries) and economical traction motors. The...

    Small turbofan for VERTOL concept (I'm aloud to dream)

    Why??? Bill, Accepting your post as accurate, I still wonder WHY there are no affordable fan jets. Please forgive my ignorance, but can you walk us through the main elements of turbine development? Prior to buying my CNC Router, I had entertained buying CNC metal working machinery...

    New Carbon Wing

    Pitch issues? Looks great Mark. Does the body shroud / fairing have any noticable affect on pitch or trim?

    HBA Bookstore ?

    Merchant accounts Jake, Be sure to read the entire boring, obnoxious agreement carefully. Some of the things that have kept me from adding EFT capabilities have to do with liability issues, funds availability, and charge back policies. You would think from all the propaganda put out by...

    Shipping large Items

    Shipping stuff. I recently found a shipping broker called Unishippers. Their contact number is 800 607 4350. I will be using them to ship some product to a customer in Chicago. Here are a few tips I learned from talking to them. High density equals more cost effective per pound...

    New kit lines

    Another Canopy thought. What if you use the depicted (or close) version and used a 3 or 4 point pantograph arm set? You could then have the works lift up and back. 5-2-05 edit to stay on topic.

    New kit lines

    CANOPY Perhaps a break just aft of the front seat back. Less LOS obstruction for the pilot (if the pilot is in the front, which make sense to me) and you could hinge the two sections any way you want. The front could hinge forward or back, and aft section forward, sideways or back, or...

    New kit lines

    Datum points? Is the fuse` length mesured from the firewall or the front of the engine cowling? Pass the Holy Hand Grenade, and remember thine number of wheels shalt be three, five is right out!
