And a question for slopers …. We had no luck tossing LAR planes into the winds off our levee’s , but our best luck was with an old balsa Tercel Glider ( remember those ) … What’s up with that ???

Gold , I think you’re absolutely right , LAR great for hovering , crap for sloping …

Carsloping , I guess that’s good when the wind is down …

Can't pull that off now, the occupants are not allowed to be that close to one another.

If you are stuck indoors and have a hot wire cutter and a bit of polystyrene foam packaging, you can make your own slope soarer and your own slope and go slope soaring indoors......

And just saying a walk along Glider with a small motor works SUPER !!!! We worked through all that culminating in the Big Horten ( just a BIG powered walkalong glider essentially ) … FUN !!!

So the walk-along glider in the video is built from approximately...nothing.

What does a motorized walk-along glider look like? IE, DIY link?

EDIT -- I found this, but the link is dead.

"Have a look at http://www.geocities.com/x_surfer2004/ for links and plans.
I haven't seen a commercially made walkalong for years other than the one linked on that page.

The secret of the walkalong glider aside from undercambered airfoil and LIGHT weight is Wing Sweep, Dihedral , and tip washout … However the shape , if you do all Three (3) of those things , it’ll fly like one .. Plenty of room for design experimentation within those parameters … and that’s just with chuck gliders …
The Big Horton (60”) WAG variant , it flew very Blimp-like , a geared J250 swinging a 12” prop …. Flown too fast and it would surely “tuck under” … On calm days it would just float around , and we got sucked up in a thermal once and had to Dive out of it … Bit scary with such a flimsy plane … But It made it , no worries … Still have it ...

Thanks. I think I'll do a half-way project first. I have a conventional DIY 30" $TF KFm wing that glides very well. By building another with no paper, half the motor and a quarter the battery I think I can have the same wing area with half the weight. Will have to tractor the motor so I can make CG with such a small battery. EZ project and I'll see where that takes me. It'll be structurally wimpy, so will have to see if I can live with that.
