    The 'daydreamers' thread...post your craziest designs and concepts here

    Hi, I'm surprised no one has suggested the Geobat (sometimes referred to as an Aerobat.

    check out this lawn mower engine (kohler engine)

    Hi, Many of the local lawnmower racing guys here use the 670cc Briggs, and rev them routinely to about 5k rpm. I questioned the longevity of these engines, and was repeatedly assured that some of these engines had been racing for their third year now without having been opened up. They say...

    The Lone Ranger - a Ranger/SD-1/Aeromax based design

    Hi, As you know, I'm cutting 1.5mm ply as below, to which I am bonding Hoop Pine. The plywood acts as little more than a template for the pine, guaranteeing me of a perfect fit, angles etc. I'm about to order pultruded CF rods from Jim Marske, and got to thinking - would there be any drawback...

    2D fuselage structures and sit on top, no sit In!

    Hi, I get that this might be a first sketch, but there are a number of things you should probably re-think. First, if the man is drawn to scale, he's not even going to be able to get a single butt-cheek onto that miniature chair. Which is way too far forward anyway. The wing chord looks way...

    Question: When do the Yahoo groups have to clear out? How long do they have?

    SD-1 Forum on Yahoo Groups is looking for a new home

    Perfect! And why not? Since when did HBA become exclusive? Let them all join - aren't we always looking for new members? This is a perfect opportunity not only to help out a whole bunch of builders, but to grow our own numbers. And me too. If we can have separate sections for individual...

    SD-1 Forum on Yahoo Groups is looking for a new home

    Hi, What an easy way of boosting HBA membership and at the same time broadening our appeal. I think HBA should be proactive and contact ALL the airplane groups on Yahoo and invite them to join - with their own dedicated section. This is a tremendous opportunity for HBA. Let's not whiffle it...

    SD-1 Forum on Yahoo Groups is looking for a new home

    Mnyes... No-one on the most active group I'm a member of likes FB. Nothing but complaints. SD-1 can do a lot better. Besides, for the value of all the "passing traffic", and the slick interface, I'm sure they can afford whatever (if any) cost might be levied by HBA. Besides, if we can have...

    SD-1 Forum on Yahoo Groups is looking for a new home

    I'm a member a number of FB groups. They are definitely not designed as real forums. All posts are lumped in a single folder. Terrible.

    SD-1 Forum on Yahoo Groups is looking for a new home

    Hi, As you might know, Yahoo is closing its forum section, and all those airplane groups currently using the Yahoo platform to keep in contact with builders are pretty much being cut off. The SD-1 group is looking for a new home. I suggested they contact homebuiltairplanes.com and suggest the...

    How much pressure needed to deflect flaps, ailerons, rudder, elevator?

    Hi guys, There is a third way. How much force needs to be applied at the control surfaces to get them to deflect? By the time the linkages reach the pedals or the control stick, various "gearings" can have taken place to get to, possibly, Radfordc's suggested 1-2-3 ratio. From what I'm...
