Bidule 55 from ECOTOP

Details

With over 6 years of loyal service under it’s belt, the Bidule has become renowned the world over as a rugged and reliable workhorse of the sky. Not only known for its superb Aero-Towing capabilities but also for it’s precise and well balanced handing characteristics as a general sports model.
Modified versions of the Bidule are even being used by our customers for both military and commercial applications.
So if the Bidule has been so successful, why have we decided to “change” a proven design?
Rather than go for “wholesale change” of an already strong and very successful product, we’ve gone for a more “evolutionary” approach. Taking on board the comments and suggestions from our private, commercial and military customers and incorporated this knowledge (gained over the past 6 years) to produce a fully coherent and truly evolved design.

Features:

  • The tricycle landing gear (which is particularly robust) was specially developed for this new aircraft. The nose wheel being fully dampened with an extra large track between the front and main gear, reducing “nose pitching” during both take-off and landing phases.
  • The ground clearance with a two-bladed 22 "diameter prop is increased to about 3.5".
  • The engine is mounted flat on a hyper strong aviation quality plywood firewall, with the mounting configured to allow the installation of tuned pipes to fit perfectly under the fuselage.
  • For aesthetics, a fibreglass engine cowl (supplied painted) surrounds the engine without sacrificing cooling, essential for this kind of plane.
  •  A tinted PVC canopy mounted on its frame disassembles easily, thus allowing easy access inside the entire fuselage from the firewall to the towing hook (supplied in the kit). Excellent for easy maintenance!
  • The two- parts wings (carbon wing joiner) are equipped with ailerons and powerful landing flaps to enable quick and accurate landing even from “tight” fields.
  • The 2.5° of wing dihedral (per wing) assure that the Bidule keeps a straight and consistent tracking and is easily controllability in turns.
  • The tail is removable, the two rudder servos are integrated into the thickness of the airfoil and are accessible via two hatches.
  • The two vertical stabilisers (fins) are also removable via 4 screws (with captive nuts fitted into the horizontal stabiliser).
  • Thanks to the lightness of the airframe, the Bidule 55 can be powered with engines from 35cc, however for those who practice towing a powerful 60cc is highly recommended.
  • As mentioned previously, although the Bidule was originally designed as a professional towing machine, as a recreational aircraft, its ability to perform soft and sweet aerobatics really take some beating.
  •  In addition it’s light wing loading, large and powerful flaps, rugged landing gear and its twin rudder configuration allow this aircraft to be used from rough short-strips even in strong crosswinds.
