my BOT is 3.0m and 5 pounds.

im running a 14x9 prop, directly driven by the E-Flite Power 25 motor, and a 65amp ESC. i can do a vertical climb out, but not sustained. after a few hundred feet i need to start pushing the nose forward.

I'd love to learn towing

Tried it twice, both birds were mine, with releases on both.

My glider test pilot " non - glider pilot - about wiped us both out - Pretty funny really - 1st try he stepped in front of my carbon / glass Quasoar at the last minute and got kneecapped


Second attempt was with my Saggita 600 and he got whipping so bad on takeoff I just had to drag him vertical and punch him off then bomb down with the tug to save it swapping tranmitters

If I try it again, I'll suspend the tow line betwen a couple of poles and try the snatch and grab method. It looks like a riot -

I'd saddle them on top but It's no fun flying the tug letting someone else fly your sailplanes. Otherwize if the fly the tug their a bit ruff on the wing's

I've seen aerotowing a couple of times and no doubt takes a bit of practice. An 8 meter ASWxxx and a big tug was impressive. Never seen the snatch method but looks cool on video. Would love to try that! My Hacker set-up can run a 18x10 prop which provides unlimited vertical but again pulls a ton of amps, though only needs a short run. I normally use a 15x9.5 HAV

broke my personal best of 1703feet today with an altitude of 1824 feet.

another flight i believe was higher, possibly in the 2000 foot range, but the altimeter didn't record it for some reason...this is the second time now.

How the heck do you see at 2000 feet? How big is the sailplane? i have a 3m Vladimir's graphite 2 and its specking at 1200 feet or so, the slimness of wings and fuse makes it invisible at certain angles too.

i did it with my bird of time with a 3m wing span. i can see it just fine, the only reason i brought it down though was in case a thermal would catch it and bring it up where i would lose it.

1200 feet is nothing for me. although i do agree that at certain angles it just simply disappears even though i'm looking right at it. i just try to do slow circles and keep it level so i can see the wings.

You guys got anything going on for this year? I'm really considering getting a MM Glidertech Marauder kit. From what I've read it's a great sailplane and the price is great too http://nesail.com/detail.php?productID=5679

Come on, I'm going out again tomorrow afternoon to try out the spoilers and ballast boxes I installed on my Spirit last night It's getting up to 40f here but I'm sure it will be nothing that warm up your way

After a few PM's and gazing at my old photo album's

Just checked my rack's and I'm still sitting on a B.O.T in the box.

It'll be my 3rd one ?? maybe forth if I do it. As I remember I even swapped out some of the material for contest grade stuff. I alway's wanted to stretch one and I been hoarding a few roll's of the original mica film. Even pondered about stuffing a tiny wee motor in it on a 2- 0z tank. I think 130" would be about right- ????

Nice the BOT is one pretty sailplane. I always liked the wing profile. 130" sounds perfect, shouldn't have to add more than a few ribs in the inboard panels to get that Keep us posted, love a good kit build

Sailplanes are great fun if you get into contest flying, nothing like competion to push your limits. After 25+ yrs. of sailplaning I took up helis, they don't need a winch or hi-start or even a large field to fly. I still have my s.p.'s, even my first R/C Olympic 99 vintage 1973!

i like the sail planes because it is something drastically different from the stress of flying a helicopter. quite often i will show off by sticking the plane in a calm head wind, it isnt going anywhere. i'll put my hands in my pocket, turn around, and start talking to people.

even a lot of people you would think would have no interest in it, run up to me. and its one of those things you don't really mind letting anyone else try.

i love having my electric BOT for super quick boosts when i need them, though on even a mild day, once its up, it isn't hard to stay up.

there is something graceful about seeing a giant white plane with super long narrow wings hover around in complete silence.

Easy to fly but difficult to fly well !

My sail plane days taught me more about flying models than any SIM ever could. Period ! Many say I have uncanny skills for saving dead sticked aircraft or ones that have a fault in mid air. My last was when a little 3-D bird with two piece wings had the rear locating pin on one wing exit out thru the fuse and into the other wing. Essentially I had one wing only, as the other pivoted around the wing rod Dangest craziest landing I ever made but it was through my sailplanes skill's. Airfoil's, balance, speed management, inertia and mass , wet or dirty, it teaches it all to you

Everyone one thinks flying sailplanes is easy, but few have spent the day aloft on a single launch, or thermal ed back up and out from 20 feet.

I had the darnest time learning to read lift even though I had a very great mentor. But once you accidentally stumble into your first hatsucker you will be hooked for life. It's like practicing witchcraft. My mentor was just plain scary good at it !!! Even with a plywood bird we called the ball bat.

I've thermaled out in rain storms, had to hold very - very long extended vertical dives all crowed out and dirty in wall clouds - just hoping to get back - and even had my Aquila Grande kidnapped by a Bald Eagle. Best is when I once hand launched my #2 B.O. T just messing around and hooked up some ground lift and went out on it .

Like to try the discus launch micro stuff but wonder If I'd get dizzy and fall down at the moment of launch. It's a blast seeing guy's thermal out from hand launches.

Real fun is sitting in a lawn chair, in a pickup doing 70MPH on gravel - during a cross country and having your Sagitta 900 leave you standing still as go'e up and out carrying 3Lbs of lead. Think I left a dent in the roof pounding : " Faster - Faster - Faster "

Oylimpic 99 ? Wow !'- that deserves a few baby wipes to clean up and a good rubbing with some fresh wool - and a few sweet whispers.

Nothing funner that showing up among the carbon wet birds with a old 2M Drifter and listen to them snicker and laugh at your $16.00 sailplane. Then to go home - snikering and laughing all the way - with all the goodies .

What the heck is that standard class gasbag ??

Pretty clean : VERY : Thought I Knew it till I saw the spar's showing thru at the tip's where they end up pretty forward - so their swept.

Fuse looks a bit like a 900 especially the canopie - or a thinned down OLY II fuse, till you see the vertical fin / wing's look like off a standard spirit but the root is pretty thin like a older Eppler 193.

Love the wide cord stab - she's a floaty - or " sleeper"

Also Like the mod to your tips and alway's wanted to try winglet's, pretty flat groovey turn's --I bet

Your school site looks awesome for those little hot bubbles and I bet theirs good flow up the subtle valley - for us sand bagger's -

Winter thermalling is great but drive's you nuts as the sink is hard to read,- or none - but them little blisters just rock you out their so small and fast.

I used to imagine it as bouncing across boiling water, you just couldn't stay with them so you just hop along,

Man I got to get my latest project done a " 20 year old woody" Snr Falcon w/ inverted horner tip's and Fowler's " Even has a FOX ! All done in clear.
so I can crack a box ! I'm gona stretch it both way's for a lil blackhead .20

WELL DONE THANK YOU !!! I see dust ! OH man I got break into my good spruce that's hidden !

We don't know, bought it at the LHS used. They were selling it for a guy so they didn't know either It is a great slow floater and I swear it creates lift to stay up on. You are right about the bouncy thermals and sink where you never expect it. It's like learning how to thermal all over again
