    A HEAVIER GOAT GLIDER

    Informative post. I'm curious how you would envision a HG being able to go on public transport? This sounds like a flying machine I would like to try/have!

    Discussion: Conceptual Design of an "Inexpensive" Single-Seat Motorglider

    Well, if you ever decide that with the fixed gear, you end up making it a pod and boom pusher - a la Strojnik - I would definitely consider helping you build it (though then we'd actually build molds to put it into production!)

    Discussion: Conceptual Design of an "Inexpensive" Single-Seat Motorglider

    Is this thread/project still moving forward? I recall reading elsewhere that another design was taking precedence, but I've been out of the loop for a while, and not sure what's going on?

    Announcing the Experimental Soaring Association Western Workshop 2018

    I hope to be there as well. Would love to have lunch again with you, VB and A2C - and anyone else on HBA who will be there.

    Flea style "Piojo Flying MiniBike"

    I prefer the stepped scarf - not only because you can use the same bit as for cutting out the rest of the parts (if your vacuum table is good) - but also because it is "almost" fool-proof in self aligning! As far as hand planes go - they are pure joy. I have about 30 antique Stanleys - and just...

    Flea style "Piojo Flying MiniBike"

    I know it's late in the thread, but as Fritz mentioned, scarf joints on CNC are pretty straightforward.

    Flea style "Piojo Flying MiniBike"

    Spent nine hours driving from San Diego to Santa Maria (300 miles) last night, through SoCal traffic (did I mention we have good weather?). Maybe I'm still too groggy, or should drink real (caffeinated) coffee... but I don't understand the above comments. Which does what? Who's on first? I...

    No, it was your turn to talk about religion... (or aviating - which is a religion to some people)

    Flea style "Piojo Flying MiniBike"

    Where I currently hail from, we declare a local emergency when it gets over 80 or under 50... The Central Coast of California is darn near perfect climate - though our cross to bear is putting up with a gazillion (that's 1,000 bazillions) bleeding heart progressives who believe that small...

    Flea style "Piojo Flying MiniBike"

    Fritz, I really need to take exception to several of your posts... I have it on extremely good authority (my seven year old granddaughter) that Bazillian is spelled with an 'A'. It is actually a Portugy word for "all the money we could have made if we kept the place as a colony instead of...

    Flea style "Piojo Flying MiniBike"

    So what you're saying is... wood is a tougher material, able to handle more than that wimpy AL pansy stuff? :gig:

    Flea style "Piojo Flying MiniBike"

    I had the exact same thought! I think that is a clever design. :ban:

    OpenTrainer: New crowd-sourced open-source two-seat primary training sailplane

    How much fuel do you expect this little trainer to carry? Compared to batteries, fuel is light. Even if it was comparable, I am not comfortable with the complexity of moving fuel around (extra tanks, lines, valves, etc., etc.) The battery presumably needs to be there anyway; a few extra hard...

    OpenTrainer: New crowd-sourced open-source two-seat primary training sailplane

    Though I appreciate that a sheet metal design may work best for a true homebuilt open-source design, such will not be able to offer the savings due to production runs of parts. A kit manufacturer could possibly make a decent side income by selling part sets at the price individuals would have to...

    Best Pour Foam? Locally sourcable?

    We buy about 70,000 lbs of urethane foam each year - there are several good sources in SoCal but we buy ours from APS (Acella) and I believe they have facilities in different parts of the country.

    OpenTrainer: New crowd-sourced open-source two-seat primary training sailplane

    I think the sentiments listed in the recent posts are the reality that must be faced. My personal conclusion is that an inexpensive glider needs to be able to self launch, and ideally would be semi-cross country capable - though low performance seems acceptable. The solution I see being the most...

    OpenTrainer: New crowd-sourced open-source two-seat primary training sailplane

    Sorry for the rabbit trail, but I highly recommend them. We have a couple of DeLorme "InReach Explorer+" units - bought out by Garmin so now they are a bit sexier and more expensive (and they jacked the price of the service plans up too - thanks Garmin). They allow two-way texting and point...

    OpenTrainer: New crowd-sourced open-source two-seat primary training sailplane

    In the process of completely redesigning our Solo (single seat sport plane) to match the Duet (two seater, hopefully someday built and ASTM certified), we have a complete set of molds here for the old version, which I've been wondering what do with (we now call this plane the 'Sport' - which is...

    OpenTrainer: New crowd-sourced open-source two-seat primary training sailplane

    No worries - I was kidding anyway. I have a ball and chain on this week: to help my son set up his new cnc and then redesign and fit out his shop. One pride as a father is that my kids want my help and expertise!

    OpenTrainer: New crowd-sourced open-source two-seat primary training sailplane

    What about AutoReply's idea of a composite "fold-a-plane"? All flat wrapped composite panels that have simple molds with self jigging fixtures? Personally, I think making molds for a low performance design would be relatively quick and inexpensive, but not necessary to utilize the advantages of...
