Hi Alan,
Still waiting for the first flight !
Waiting for a decent wind to avoid any risks (the machine need to be like new for Retroplane  :D  )
I'll bring the Opel with me at the Nationals...
We'll see...  :?:

The Opel has flown !  :D

Well, back from Retroplane 2007 ! The Opel did is maiden voyage the saturday of the meeting.
To tell the truth, the real first flight was a bit.. desapointing !
Launch, went straight, but the glider did not want to go up !
Flew like this for 5 minutes, and then land... We've just look at each other with Joe, thinking that this thing will never fly (well... 100% scale, the original did not much better !  :wink: )

Analyse of the flight, then, that was obvious that the CG was a bit too much forwrd...
Removed around 40 grs of lead (the only piece of lead I was able to remove...) and off we go again...

And we saw the light, right after the second launch !
What a flight !
the 40 grs made a huge difference, even if the machine is still nose heavy.
Just the trim at the ailerons to be touched, everything else is fine. Rudders are really powerfull (rudder Joe, rudder !!!  :lol: ) and the shape of the glider in the sky is really uncommon ! Really looks like a WWI bomber with the two tail booms !
I flew lots of low passes, just for the pleasure (and the photographs  :wink: )
So, here are a few pictures... A video will follow soon (and more pictures...)
Enjoy !

The launch... Where you try to think if you forgot something !

Looks Great Fred  :clap:  :clap: . Wish I was there. I heard reports that Retroplane was rained out the first two days. Is that right. Just like Ireland then  :D  :D.

Well, we had a bit (lots in fact...) of rain 2 days before the event, then, a bit of rain Friday morning, Joe flew first on Friday evening with the L213 (boooooooohhh !  :lol: ).
Saturday : flying all day
Sunday : Prices in the morning, then 1 hour of rain, then slope for the afternoon ! Just 10 minutes of rain during the event on sunday. Lots of people left, but around 30 stayed, and we were able to fly for the remaining of the day (with an even better wind than the previous day  :D )
Monday : Flying in a new slope in the afternoon

So, not bad !

Hallo René,

Thanks a lot for sharing the photos (Horten... =P~ )

For the Opel, strange, compared to the original photos, the lettering is the oposite of the original one, like the Opel Rak in the landesmuseum of mannheim  :?:
Any idea what the tube frame is ?  :?:
