RE: Komet F3A Bertolani
Hi Bem.
The model is an F3A from '70 years, out of production from many years.
The manufacturer was "BB Model" or "Duebì Model" (Benito Bertolani).
Now the company is called Eurokit, but they don't produce anymore the kits but only landing gears and accessories.
The model on the photo is built from an old kit in the 2005, weight 4,4Kg (9,7lbs).
The engine is the old Supertigre G60 Racing, also the engine is from '70 years.
11x7 carbon fiber propeller, entirely "open" tuned pipe.
The clip has been made today, with 37°C (99°F) and very much humidity in the air.
There are many version of the Komet from Bertolani... this is the Komet 1: fuselage in fiberglass with tail and wings in polystirene+obeche and external tuned pipe.
Massimo.
