Gentlemen :

I apologize for the confusion generated by the earlier posting . I hope that this proper presentation of the model and my problem of figuring out the nacelle motor drive is remedied here .

The inspiration for this model came having scanned some prints from an Airpower Magazine article some years ago . I used my scanner to scale up the drawings and made cardboard templates for all of the hot wired cut pieces . Basically , this model is kinda thrown together . Stand-off scale-ish . I hope that it flies !

As previously mentioned , the Osprey is made from Dow Styrofoam SM and covered with 1/2 oz. fiberglass cloth and epoxy mixed with an automotive white pigment . The model weighs in just shy of 4 pounds for its 62 inch wingspan and 52 1/2 inch length .

I am planning to use a pair of Aeolian 3542C's for motors , 60A ESC's , 4S 5000mA battery and a KK2.1 flight controller board . This set-up should provide ample power for the hovering and generating enough speed for this light-weight in number of square inched airfoil .

The pix included show the bird as it sits now and should detail some of the handi-work completed and the remaining work left to do . Basically , all of the heavy construction is done .

Thanx to those who have made suggestions thus far in solving the nacelle drive problem . Thanx for the blog support and further comments as they are always welcomed .

Gentlemen :

I was cleaning out my picture files on my computer and ran into a couple pix of the V22 Osprey that I gave up on a few years ago . The problem of finding a gear drive / escapement to operate the engine nacelle rotations was the deciding factor . I thought to use a winch servo found in the sailing models but could never find one that would work . With the advent of the more powerful electric motors , this project will probably be resurrected from its place in my storage area .

The model is constructed mostly from Dow Stryrofoam SM (blue) and is covered with 1/2oz. fiberglass cloth and epoxy resin . The paint and primer is of the automotive type .

Should anyone have viable suggestions for driving the nacelles via its 5/32" steel rods within the wing , please feel free to inform me . This is the only aspect of the model which is left unresolved . I would love to see this one fly . A large 54 inch wingspan bird weighing some 3 1/2 pounds as it sits now .
