Today is my super thermal day. I started flying my Adriana electric LMR sailplane to map out the thermal at around 1030am to no avail. Only to get attacked from eagles looking for prey. Luckily I pulled a loop over it and managed to intimidate it enough to chase them away from my plane.

At around 11am, Tony and me started to bungee off our pure thermal sailplanes and on 1 flight, I thought that it was good as I flew it for almost 4 mins, as I usually only get about 2 min+ without thermal.

At about 1140am, which is my second last launch of the day, I managed to hook up one good thermal, consistant enough for me to work my Elf up to HDB roof top height and then followed by a big boomer that brought it sky high until my Elf was literally specked out.

By the 13th minute in flight, I was already near 1000' and I started to get very nervous and neck strained to fly a glider which is only a black dot in the sky. I started to do some wild manouvers to get out of the thermal. When I brought back to about 600', I totally disengaged it from the thermal and it slowly made its way down. At about the last 50', I can feel that both our planes, which were flying directly above the PFW field, is in the sink, just right behind the thermal which I got earlier. The last 50' sink rate was faster than usual and I stopped the clock at 17mins 35 seconds when it landed under my feet.

Although I got thermal rides before, this is my first boomer with a pure glider on flat field. I left home with a big grid on my face, and thirsty for more in the future.

Last but not least, I hope that this report will entice more glider folks to join us. Though the Northeast wind is gone, the thermals are still around!

Congratulations...

Kekeke the presence of the eagles soaring around is a good sign

By the time I hooked up the thermal till my glider became a black dot in the sky,they were nowhere to be found. If I fly any longer, I'll soon become a black dot standing on the field.

Joe, what wing span (minimum) you suggest to get this fun? Thanks.

[joe yap]

I'll think that 1.5 to 2 metre span will be a good place to start. You'll need a very lightweight glider though.

I'm building a re-designed and reduced size Carl Goldberg Sophisticated Lady with Selig 4083 airfoil wings. It has bigger wing area than the Elf and I'm targetting to keep the weight down to have a lower wingloading than the Elf.

...sure it was 17 mins anot ? ...felt more like 25 mins to me !

I can verify Joe's attempt, it was really a sight to see his Elf specked out at PFW, ...this only proves the viablity of Hi-starts launching for TD flights.
I think we did about 6 - 8 Hi-starts launches each and the launch were getting better and better each time as we discovered the technique to achieve the highest possible launches ...towards the end we were achieving consistant 200' takeoffs.

Boy, I can't wait for the Hi-starts that'll launch our HLG up to 500' ...that's where the boomers are !

[ammo]

Ok i think i'll set the cutoff date for the hosemonster order to this friday.

After i settle that, i can go about choosing already

[Jack_Chen]

I am interested. But roughly how much is a hi-start ah?

Any idea what is the tensile strength?

I found this website, they sell the latex tubing but need more information as they have few resistance strength.

Hi Joe,
Can this 1.5m ship be winched up? I saw that is is relatively simple to build and may just give it a shot.
The Terminator plans and the template are all in there.....and uses only 2 servos!!

Dennis, this one looks okay.
