Check it out on the sailplanes page of the Isthmus Model Co. website.
The Soprano is the super RES design you have always dreamed of and it offers a new dimension in large lightweight RES designs. At 122" span the model has a all up weight of 47 oz. The slim Carbon / Kevlar fuselage has removable nose cone and inner shelf for radio gear. There are two Kevlar tubes in the side of the fuselage for ballast slugs. The carbon/Kevlar molded D-box sheeting has raised the standards to a new level, and reaches levels previously unequalled in strength versus weight. The three-piece wings and removable all flying tail ensure the model is easy to transport. The wing panels are constructed in an open rib "D" Box structure, each of the selected balsa ribs is fitted with a carbon cap strip, the Carbon / Kevlar "D"-Box and Carbon capped sparswrapped in Kevlar combine to produce an extremely strong and rigid wing. The wings are covered in Oracover and are designed for competition style launches by winch or hi-start. The all flying stabs are of similar construction to the wing. This model is the culmination of many years of experience in this type of construction. The MH32 wing section gives the model an extremely wide speed range and excellent thermal flight characteristics. The handling is outstanding and the model will hold a turn as if it were on rails but will change direction at will due to the lightweight tip panels.
Next shipment in August. Email me to get on the list and details.
Cheers,
