Slope design
 Wing span:    74.5" Airfoil: rg14  Flying weight   48 0z (58oz with brass ballast)
Opus w is our latest high performance slope glider. With it's all molded pre-finish fuselage , wings, and tail you will find yourself in the air flying in no time at all. The Opus has a wide flight envelope, capable of both standard slope up thru racing and to the high stress world of dynamic soaring. You will not find any better finish on another commercial glider , the finish is pre painted in the molds giving you the flawless finish you expect from a high end molded sail plane.

 

Wing:  The wing is a one piece hollow molded construction. The skin is a fiberglass roacell  lay-up with a carbon capped spar. All servo bays have been pre cut  and servo covers trim to a perfect fit. both ailerons and flaps have molded live hinges and control horn pre-installed. There is a ballast tube installed ready to accept up to 10oz of brass ballast, which are included. All that is left to you is to make the aileron , Flap push rods and mount the servos.

Tail: Also hollow molded with control horns pre installed. Same live hinge the wing. The tail bolts to the fuse via two nylon bolts.

Fuselage: carbon reinforced fiberglass . pre finished with both wing mounting and tail mounting bolts installed.

Setup Recommendations

The CG should be located at the front cutout for the ballast tube (25/8 back from the leading edge of the wing). Note: My most recent Opus took 7 ounces in the nose to balance and had a flying weight of 50.2 ounces.

 Elevator: maximum up and down. Refine further on the first flight by pulling full elevator in a loop to the point where the plane is on the verge of a stall; then back off a bit. In addition use a lower setting when flying with ballast.

 Rudder: 5/16 throw right and left

Ailerons: throw up and 5/8 down gives tons of throw for maneuvering. You can cut this back by one third any you would still have plenty.

Aileron to Flap Mix: Mix flaps so that they move 5/16 at full aileron deflection.

Camber Mode: Drop the trailing edge 1/16 and mix in enough up elevator to put the plane in a slow climbing mode.

Elevator to Flap Mixing: If you setup your Opus correctly, you should be pulling full up to nearly full up when pylon turning. With full up elevator the flaps and ailerons should come down a minimum of 1/16 to a maximum of 1/8. Be sure set an offset on the mix so that the mix does not begin until you pull about 40% up elevator. The last thing you want is for this mix to kick in while your flying in between the pylons.

 Crow / Landing mode:  
Setup 
1) Flaps down full and down elevator compensation.
2) Flaps down full, ailerons up 5/16 and down elevator compensation.
