During extended testing on one of our prototype Bailey 4V-200 engines we have discovered that the lead residue from AVGAS can coat the exhaust valve stems sufficiently to cause the valves to partially seize in their guides.
We have been using AVGAS for economy tasks in competitions for several years in BAILEY 150/175 engines with no problems, however we would now recommend that AVGAS is not used exclusively in any Bailey Aviation 4 stroke engine.

The new OMEGA builds on the proven three-line concept of the 2009 World Champion's glider and the X-Alps prototypes.You can see that this latest ADVANCE flag-carrier has evolved from past sporting successes.
With an aspect ratio of 6.8 and a useable top speed of 59 km/h the omega 8 is the best performer in its class.
Boomerang 7 will provide you all access in most flight condition and more stability with 3 lines system, the unique GIN rigifoil reinforcement on wing section.It is developed after the Italy Super-Final version,and improved its performance in climbing and stability in turbulance condition, of course pitch stability which is now the essential characteristic of the new generation wings.
It also has a new significant feature - new round shape of inlet which helps to keep the pressure of the wing at high-speed and the mesh system on the leading edge which works as a air-valve to be opened at high-speed(as you push the bar) so that the pilot can keep the acceleration speed in the turbulance.
ADVANCE pay great attention to small details. Sewn-in compression and Mylar straps increase the canopy stability, partially closed cells increase the internal pressure and the winglets decrease the induced drag (vortex effect). Velcro closures on the wingtips make it easier to remove sand, snow and debris from the glider. Like all ADVANCE models, the OMEGA 8 incorporates a swivel on the steering lines and different brake handles with magnetic clips, depending on the canopy size. The many small but important details like these add the finishing touch to the product.
GTO -"Gran Turismo Omologato"- was a term originally used by Ferrari, and later by Pontiac. GTO denotes a race car that has been made street legal. The Boomerang GTO was conceived in this spirit. Gin’s aim was to design a wing with a performance level that had never before been reached, but that would still be certified. Like with its predecessor, the Boomerang Sport, no compromises on handling and safety were allowed.
