HW 4 FLAMINGO 1:3.5 SCALE

Harold, there was quite a lot of wind that day, maybe 25Kph, and it was sometimes gusty near the ground (where I like to fly Very Happy

) There is no instability in the model's handling, as perhaps the stall demonstrates?
The HQ35 section has good penetration, even with 14% at the root. The only downside at the moment lies in the ineffectiveness of the spoilers, but that will be cured by programming more up-aileron in the Tx.

I'm still using the Flycamone2, but with the 1000Mah Extreme clip-on battery, which cures all the problems the camera had previously...

Congratulations for this flight and the video (and music) quality!

On the Sohaj, 3.75 m, weight less then 5 kg, I have the HQ 3.15 – 12 wing section.
After long trials and problems in the beginning, because of wrong thrust line adjustments, it is now flying perfectly.

I confirm, this is really an excellent section for our gliders. It can be used for low and fast speed. Penetration also is excellent.

Your Flamingo is larger and I can understand that 14% is better adapted.

Alexander, all I have is the information in Martin Simons' book, 'Sailplanes 1945-65'. After that, I used my imagination Very Happy

Dear Chris,

I only found these pictures on the Internet, seems to be an early version...

Regards

Yes, Martin sent me these pictures too... I think this is the Flamingo some years later with some terrible modifications to the canopy. I was happy to go by the 3-view drawings in the book instead!

By the way please notice the nice glider (twoseater) on the left is a Spallinger S25!

Thank you for the information Alexander: I can believe the cockpit being modified at some stage, but probably not the position of the tailplane...never mind Very Happy

The Spalinger 25 is on my list too...!

Laurent, global warming has been kind to us this year, bringing back the westerly winds... Cool
