How many gliders can you count?

Sunday at the slope.

From another view.

Let's count :

Unknown balsa, alula, blade, crazy banana, serenity, mini salto, 2m spyder, 36" raptor, jazz extreme, cularis, 4m china ASW, baudis salto, le fish, CMpro discus, left over of Ehawk 1400, weasel, mini fox, ASK 21, sierra, ASW 27, mystery 2.6m.

Thats 20.5. There's still at least another 5 at the other pavilion and another 5 or 6 in the air. More than 30 of them woo hoo what a huge turnout. Weather was great, sunny and cloudless, thermals aplenty and good periods of lift came on and off. Beside the few not-too-serious mid airs, everyone had fun.

CNY slope pics

Some pics from weekend's slope. Its the CNY holidays and the winds normally reach peak during this period. Well, the wind is definitely blowing but the direction is slightly off. The lift came on and off but nevertheless it was the company that made it fun! Hope there are more good weekends ahead.

Had to put down both back seats to transport the planes to slope

All want to molest the new toy for the day. Ammo's Zoom!

With a 3.2m wingspan and a fuselage almost as tall as WY

Setting up Zoom

Ready for launch. It flew beautifully with good energy retention. Luv the sound it makes as it cuts the air.

Pilots having fun.

Getting ready for launch

Fish covering

All ready for covering. Used Oracover , bright n visible pearl yellow with pretty pink. This is my first time covering, it took awhile to get use to it, there were some some crease and wraps along the way overall turned out quite ok. The quality of the Oracover is good, the adhesive is activated easily and it sticks quite well to EPP without the use of 3m77.

Covering

Trim the cover to about 1 inch oversize all round

Iron was set to 250~300F for the full balsa surfaces.

Pretty pink.

Bottom of wing in pink too.

Fuselage in yellow, Oracover doesn't stretch much so small pieces of covering to go around the edges first.

Covered up with 2 whole pieces on each side.

All covered up

At this point i compared the wing sizes of Weasel pro, Elster, Banana, Fish. Le fish wings is at 1.65m, ops may have problem fitting it into the car.

Drew out some designs and cut out the templates for the trims.

Assembling

At this stage its time to glue everything together. First the wings are inserted and Gooped to fuselage

Apply Goop to filer and slide in between fuse and wings

Hole cut in the fuse to accommodate the connectors. Taped over and covered up.

Check the incidence before gooping on the horizontal fin.

Vertical fin next

Ensure all squared up.

Trims applied to wings
Hinge

Over and under tension hinges use to hinge the elevator and rudder on.

Control horns attached and looking good.

C.G

Left one last step, thats to get the C.G. The 2 small weights that were glued in earlier was not enough to balance the plane at 2.75 inch from L.E. Had to do some surgery and added more weights.

Cut open the front of the fuse.

Weights needed to get C.G at 2.75 inch from LE.

Tons of goop poured into the nose.

Surgery done.

Temporary design in case need to adjust the C.G again. Fishy!

Finally all done! Going fishing, flight impressions in next post.
