Home: Madrid, Spain Born: Dec 21, 1953, Larache (Northern Morocco, governed by Spain in that time).
Club Membership:  I am affiliated to FENDA (Spanish Association for Air Sports). I am a member of a RC club called "Club Radio Control Alcorcon".
Education/employment:  My education is equivalent to a medium college level.    I am a professional helicopter pilot since 1980, holding a Commercial Pilotīs license with IFR and Instructor ratings. Now in charge of the Instruction Section at a Helicopter Service in my country.
R/C experience:   I got started in RC in 1979. Flew airplanes, motorgliders and slope soaring.  Became interested in RC autogyros in 1985, when I built a single rotor model that barely flew. A small twin side-by-side gyro followed and flew well.  First successful single rotor model, with flapping hinges and a small wing with upturned tips (Whistler type) in 1987, fitted with a .10 engine.  In the following years I built and flew several single rotor models, with two or three blades, always with flapping hinges and rudder, elevator and throttle controls.  I eventually eliminated the wing, but retained upturned tips on the stabilizer for lateral stability.

In 1989 I thought of achieving control by tilting the rotor head (direct control, just like the full sized gyros do).  Started by fitting a tilting head (roll control only) on one of my rudder/elev models.  It worked!  The model banked and turned solely by means of the lateral rotor control.  Sometime later I designed a tilting mechanism for both roll and pitch that I successfully tested with a .10 engined model first and later with a .15 engined one.  One photo of the latter was published by Model Builder in 1994.  Since then I have flown mostly direct control model autogyros, the rotors fitted with flapping hinges and normally three bladed, engines ranging .15 to .25.  They donīt need any rudder or elevator (I usually hand launch my models) with the exception of a small 2-blade DC gyro with a strange vertical fin in which I employed a rudder along with roll control for better coordinated turns. 

I also have built and flown a Synchrogyro (inspired in G. Chauletīs design).

I sometimes fly RC airplanes but my main interest in RC modelling is autogyros.

In past years I have done several aerial sports:  parachuting from 1975 to 1978, gliding in 77-78 and got a private pilotīs license for airplanes in 1976, also had a basic aerobatics training course.
