Lovely.  Done again I would have built it with ailerons, but it flies fine as a 3ch job.  Such a nice Storch kit, and we seldom see it built.

Hi Bill,

Great build.
Did you ever weigh it? And what R/C do you use?

The only thing bothering me are the windscreens.
What glue did you use?

Best regards,

Alex

Nice. The Storch was my first ever balsa airplane. I often wonder if my Father knew where that kit was going to lead would he have brought it home?

Yes.

Thanks to our fathers,

the storch is comming along quite well.
Sitting over the Undercarriage at the moment.
Altered the design materials a bit and try to fit in a "suspension".

Thanks, it uses BW 2.5gm servos and done again would have been an aileron flyer.  Not a bad flyer, but scale ailerons would be nice.  It's probably closer to 4oz if I remember correctly, which really isn't a problem for these 24" models, contrary to what some say, who presumably haven't actually built and flown them.  The motor is a small ELE of around 10gms if not less, if I remember correctly, smaller than the common HXT 10 gm outrunner.The glass was a chore!  I tack the glass with CA, and then glue the remainder down with Pacer canopy glue.  The CA tends to whiten the glass, so I use as little as possible.  It was applied with a knife tip to avoid excess.  The slat was also made as scale as possible, with an airfoil section actually sculpted into the slat.  It seems to fly fine with it, using the 2x entry to exit gap formula, of course as closely as I could adhere to it at this small scale.

My Guillow Champ (same size as the Storch) is at 136 grams and using a lot older technology motor (with brushes) producing about 19 to 20 watts of power. She is also equipped with ailerons. While I don't hand launch her she does fly well if I can keep her out of the trees. Don't worry about the all up weight just make sure she is balanced well (a bit nose heavy at about at the 22% chord) You can move the center of gravity back to maybe 25% after the test flight.

Bill do you know the CofG for yours? I wonder if the LE slats have any effluence at this scale.

All the best,
Konrad

I'd have to check it with the battery installed, as it's a bit of finagling to take it down from the strings, hanging in-between a host of models.  OTOH I remember it being at around the 22% as a starting point and maybe a bit nose heavy if anything.  The last time I flew it was a windy day and it did well, after tweaking the thrust angle.  That was what I had some issues with getting right, being a 3ch model.
