Default EC-52 vintage style motor glider

The EC-52 was designed and built from June 2006 to April 2008 by my uncle Jose Maria "Pepe" Cardin as a tribute to the free flight AMA Grand Class A and Open FAI motor gliders from 1947 to 1955.

Design was made with AutoCad program and then a CNC mill machine was purchased to cut all parts from the drawings and proceed with the building at his home in Madrid (Spain).

Model specs are as follows:

Wingspan: 3.015 mm (119 in)
Wing surface: 87 dm2 (1.349 square inches)
Wing loading: 35 grs/dm2 (19 oz/square in)
Wing Profil: Wortmann 60-126
Horizontal stabilizer profil: NACA 0009
Motor: AXI 2826/8
Propeller: AERONAUT 13 x 6"
ESC: 60A
Battery: Li-Po 3S 11,1V 3.200mAh 30S
Radio: FUTABA T7C 2.4GHz FASST with R607FS receiver
Servos: FUTABA S3003 for elevator, S3003 for rudder and 2 x S3102 for ailerons

Unfortunately during a vintage model meeting in 2015 the nose collapsed diving to the ground due to a brisk maneuver, leaving the plane stalled and falling in a dethermalized state, breaking the main landing gear area. The model was stored damaged till last May when I personally took the work of repairing and reinforcing the broken area.

Finally, yesterday with an appropriate weather forecast the model got to the air again for a successful remaiden, making two 10 minutes flights using just 40% of the battery capacity.

Hope many flights to follow now with greatest security and confidence.

Best Regards from Spain.

Jesus Cardin

Default Where can I get plans for the EC-52?

Hi JC;
Beautiful old timey looking ship, I would luv to build one, but need plans.
I did a one time quick search on the net, lots of large old-timey looking gliders but no EC-52 at all; so I will appeal to you. Where can I get a set of plans?, Can I download off da net, or, what is the cost for a set of plans.
Will close for now, best regards from Wickenburg, Arizona, USA.

Joe Nagy.

Thanks for your recognition and liking the model, Joe!

As explained the EC-52 is an own design from my uncle Jose Maria Cardin and it never was intended for offering or selling the plans. Anyway as he completely designed the model and draw parts plans and assembly sletches from AutoCad software for bot cutting the parts and the mount the airframe, I will ask him if he conserves the archives and a way to send you them in an easy to use format.

Let me some days to comfirm you availablity.

Best Regards,
