Csoda Electro-rubber

 I finished my CSODA Electro Rubber model and it's  ready for the SAM 2025 events.

 

This is a kit that was given to me by Tom Ryan and he got it from PACO Modell in Budapest.  This is the same model company that made the Pelikan

that I’ve been flying for the last year.

I’m also planning on building a couple of other Electro Rubber models that performed well in the World Champs:  SOKOL 465 G and the VEGA 5.

What causes one wing to stall before the other

 

 This will happen when you turn with too high an angle of attack, particularly with  rudder only (as in an OT or RES sailplane) to control your turn. It's not the mysterious "tip stall" that surprises too many.

Playboy Junior

The SAM site lists 5 Playboy Juniors. They differ in scale and aspect ratios. Some are slab-sided and some have 8 longerons like the Playboy Senior
a slab sided Playboy Jr. 46 seen in Slovakia

1950 Csoda (Hungary)

 Here are a few pictures of the build of the  Hungarian PACO kit called CSODA (Miracle) rubber design for SAM Electro Rubber event.


 

As in the picture it is weighing in at 8.75 oz ready to cover.

The span is 52”, wing area is 235 sq. in. Tom Ryan gave me the kit to build for the event.

 

Thanks Tom,

Garami Strato Streak (Speed 400)

 Flew well.  Might want a tad more nose weight.   Frankie was surprised that the ESC was a throttle.  He thought on/off.  Will take some getting used to.   Elevator needs a little taming, not sure about the rudder.  Three or four flights, each one better, A bit of breeze but she went home in the same condition she came to the field.

 

Stay well.

Hello, Thomas.  I hope this finds you well and thought you might enjoy these shots.  It flew a treat.   Your brother was on the sticks with Francis X standing within about 10 inches of him.   Beautiful aircraft.  It wanted a bit of tuning of the radio and a bit of expo.  Still a thing of beauty in the evening light.

 

stay well,

kind regards,
