I found this photo on the web of DG 505 I think, with lovely red nose and tips so this is the way I will spray mine .
This single seater ASW sports a luminous red nose also popular but finding suitable paint is a problem , its not available in 2k , but nice and visible.

The tape measure is at the 4mtr mark, time to set up my new feather cutter built for me by Peter who hopefully is busy with his Go Big glider.

I don't want to hijack the blog completely for the Discus so I'll finish off with some great links for those either building or planning to build one:
Good entertaining and informative review by our very own Lionel Brink (keep an eye on this one regularly as he may give us some photos to include as well). http://www.excelnet.co.za/berg/discus.html
RCGroups Forum with building and flying info, lots of mods and "how I did its". http://www.rcgroups.com/forums/showthread.php?t=604218

But that fuselage shape ... oh very sexy. Blue tinted canopy comes with the outline painted and needs to be trimmed a little to size. The black plastic inner part of the canopy is however a real problem as it is actually too small to fit over the fuselage - but got it all fitting together with a bit of squeezing, stretching and trimming. The wings and stabiliser are built from balsa ribs, fully sheeted with balsa and covered in a very tough iron on covering. The winglets and servo covers are plastic. Control horns and quick links look a bit on the small side but I used them and all control surfaces ended up very firm and positive.

These little birds are so fragile yet incredibly tough. They migrate all the way form Europe. Make that perilous journey and then sadly get struck by a model glider. All that space and still this happens. What a shame!
Michel Zimmerman soon crafted a little cross and we dug a grave and buried the poor little creature. May it rest in peace!
A lovely way to spend a saterday ,flying and discovering more about full size gliding which has much in common to R/C gliding.
Here are some of my photos taken at the Brits gliding club outing.
A range of gliders hidden away in the hangers from old to modern, some sporting the latest in wing-let designs.
I am sure all BERG members and family who went to Brits enjoyed the day which was hosted by Chris an accomplished full size and model pilot ,who with his fellow pilots made us feel welcome
Thank you .....we will be back.

Safely back on mother earth after a thrilling flight.
Samba - The Tug
Chris Adrian of the Brits gliding club requested us to be at the Brits flying field at round 11 am. We met the friendly members of the Brits Club and then started to prepare / inspect the 2 x Ka7 tandem trainer gliders for the days flying.
First thing we had to do was to wash the Gilders. Both the ka7 gliders are in the region of 45 years of service but they built them well those days and obviously are well maintained.
Evan and Piet washing the worthy of the sky old ladies (Ka7 Gliders)
Ilma about to go
Once done we pushed them to north end of the 900m tar runway and first off was Ilma in the blue and white Ka7. With Kurt and Chris already in the air, we were waiting for them to land as the Samba aircraft had to double up as tow air craft and in-between for those that wanted to fly the odd flip.
Then it was my turn in the cream and red Ka7, and Chris showed me how to do the pre-flight inspection and then we lined the glider up on the runway. I got in front and with the safety belts tested, we were ready to go. We waited for the tug to turn, hooked up and away we went.
The Samba tug pulled us smoothly along and just before the halfway mark the glider was airborne and a little later the Samba was in the air. Nice thing about the Brits airfield was that there are some lovely grass fields at the south end of the field should you have to abort the launch, but once we came out of the ground turbulence the Samba gained steady height. At 2000 the tug got into a thermal and It was just amazing how quickly the combination of tug and glider gained height when this happened. Chris dropped the tow at round 5600 ft and promptly turned back to relocate the monster thermal we just had.
As we got back into the lift the vario gave a nice kick up to +1.5 m/sec and I was surprised to see how narrow the boundaries of the thermal was. This kept on reoccurring for a while until Chris centered the thermal and then we had a steady climb of +2m/sec to 6500 ft. At this stage Chris gave me the controls which felt very light and responsive. The coordination between ruder and aileron is very important and will require quite some practice.
Chris then demonstrated a mild stall and then we bled off some height with steep turns and finally with the spoilers and then we were lined up on runway 02 for a perfect landing.
All together a 30 min flight of great pleasure, thanks Chris.
By this time some cloud activity blocked the sun and the rest of the afternoon not much lift was around.
Evan and Chris were up next but the conditions was not to good and they were down and landed shortly after the tug touched down. It later on became clear that my flight with Chris was the best of the day and that really is something I won't forget in a long time.
Where's that lift?
Len getting straped in for the ride.
Fortunately the weather held out and Blake, Russell, Mike and Len all got their flights in.
All too soon the day was over and with the Gliders safely back in the hanger we return to the club house for a braai.

As Evan and myself drove home we were treated to a beautiful sun set, ending off a great day’s flying and I am sure that we will be back again. For those BERG members that could not make it this time, stick around you will get your chance. So watch this space.
O yes, I nearly forget, thanks to Chris and the members of the Brits Gliding Club for a fantastic day. The canteen and ground support is also 5 star.

the final product.(1st prototype)
