Is there anybody in there?
Just nod if you can hear me.
Is there anyone home?

Now I got that feeling once again.
I cant explain, you would not understand.
This is not how I am.
I .........have become............ comfortably numb.

the Floyd...Pink that is

OK...I'll start with a show - if you tell...

I was a tad bored with the sanding on the other builds and wanted a diversion, so I found the enlargements of the plans I had drawn up but set aside while I pondered building materials for a slightly larger test copy.

I got a lot of foam core...so I cut the formers last night for a 2X upscale of this popular kit, just because it looks cool...and sinister.

2X SRX? Very cool, what do you plan to fly it on?

Fly it on?

Yes, I did hear long time ago about GCG's original BT50 plans, and might have even seen those once, but I wasnt intrigued enough until I decided to do a BT80 version, with light materials of course. Since I already had developed the Astron SST specifically as an HPR glider there wasnt any real need to 'reinvent' another similar sized/constructed glider so I went light.

Once Aerotech first came out with the F20 Econos (back when they were really Econo and 65ns) I then wanted to make this workable on that motor, and only could end up at around a pound for both pod and glider. Thats when it became apparent that standard foamboard wouldnt do since that much of it drug the empty CG aft, necessitating increased pod weight to ballast, the dreaded 'double penalty syndrome'.

Adams Readiboard solved this, as it is half the weight as standard foamcore but also not quite as strong. Still, this worked so well that I ended up making an entire series of BT80 midpower gliders workable on F motors.

Over time, the F20 has become no longer really 'econo', todays ValueRockets E15 now is. And so, using the latest 150 in sq/oz board, now we can make nearly the same sized gliders workable on the new E15s. Currently, there is my BT70 SkyDart (2.25x), BT70 Maxi Marauder, and several more with others planned. Just keep em around 12z and up they go.

Once I get a camera, I will post pics of these, and may do a build thread of the Maxi Marauder, the easiest glider of this size and type to build and fly.

I bought a Goldberg Falcon 54 at a yard sale with the intention of learning to fly RC figuring a rocket glider wasn't the way to learn to fly

Soon as I have a spare \$100 for a radio and servos I'll be learning
I bought a Goldberg Falcon 56 in 1982 with the intention of using it as a mothership for drop testing experimental rocket powered gliders...didn't quite go the way I thought.

I didn't much like power aircraft at the time, so I set the Falcon aside (still have it) and transitioned to RC sailplanes and learned Rc that way...it became my primary hobby and I met a lot of great people...
RC sailplanes is a great way to learn...very forgiving, and thermal hunting is fun and will be useful in competition if that's your intention...

I'm so glad to see folks realize the way to fly an R/C RBG is ot leeanr ot fly R/C first on a real R/C plane or glider, and not try to learn on rocket boosted gliders. I know of only one person, Ben Roberto, who ever learned that way. And he was so dedicated that he went on to fly S8E (E R/C R/G) on the U.S. Team. Everybody else who tried to learn that way, they are not around anymore (or if they are still around in rocketry, they are not doing R/C that I know of).

Wow a lot of good old Goldberg birds! I really learned to fly R/C for real using a goldberg Ranger 42 (on a .049). Then moved over to a Goldberg Gentle Lady sailplane to learn thermal thermal flying (I still have one and it is for sale). As I mentioned in this recent thread:

I did not get "seduced to the other side" THAT much, but I did, and still do, find it to be a great SECONDARY hobby.

What I would suggest now is an electric sailplane. Does not glide quite as nicely as one that is not carrying the motor and battery mass, but it beats the hell out of screwing with hi-starts, and that assumes you have a nice BIG local spot, with SHORT grass, to hi-start with. I ran out of such a local place, so that forced my hand to go electric When I converted my "VeeT" HLG to Electric, I got three 1200 mAh NiMH packs and a good field charger. I could fly for about 30 minutes total, with 6-7 minutes of motor run time and a lot of glide time, even if there was just dead air. And with the three packs, I could land, swap packs, put the old one on to recharge, and go up on the new pack, and in theory could fly all day long with nothing more than about 5 minutes from each landing, to battery swap, to putting old battery on charge, and another take-off (though I'd usually take the opportunity to get some water and even take a break in some shade on hot days). Contrasted with hi-start flights where most of the time was spent on the ground, getting the hi-start, walking and stretching the hi-start, and so forth, for sometimes 4 or 5 minute flights.

A nice choice would be the Eflite "Ascent" electric sailplane. it is an ARF, though needs a bit of work to complete it. Both wings come apart for transport (I think the span is about 5 feet, my VeeT is 5.5 feet)

That pretty much sums it up too, for me anyway.

There is something "seductive" about sailplane flying...serene, gracefull, and a quiet afternoon up there in the clouds, looking where the other birds go,and playing tag with a kettle of hawks is a joy.

Yeah, the Hi start gets to be a pain in the butt, and even hauling a big battery and electric winch from the car to the site and laying out and retrieving line gets to be a hassle as well...

That said, I have a couple of electrics myself for that reason, and innovations in batteries and motors over the years have really made some nice things possible that were not availabel years ago.

(Just be careful with the LiPos........)
