Macarena - combat wing

-

 This is a 920mm span composite combat wing 




The wings are hotwired out of EPS.. It has a built up a carbon tow top and bottom cap strip acting as the spar. The bottom hinged elevons have a live fiberglass hinge.  There is a LE carbon fiber cap strip and also a thin CF tow strip along the TE to prevent chipping. The whole thing is glassed with 30 gsm fiberglass

.The winglets are fiberglass, carbon fibre & balsa composite

The canopy is taped foam

Dimensions

    Root Cord = 30.5 cm

    Tip Cord = 14.5 cm

    Sweep = 30 degrees

    Span = 92 cm

    CG @10% SM = 15 cm from LE

Electronics

    2307 2550kv motor, 30A esc, 2 x 9gm micro servos, 1500mah 3S bty

Dry weight = 325 gms, AUW = 480 gms




With the CG at 7% , there is about 2mm up elevator required

Excellent flyer... tracks like on rails..snappy in loops and rolls.. and good glide ratio too

Flipper - Plank flying wing SAL

 This is a Plank flying wing for SAL or bungee The dimensions are  Span = 875mm, Root cord = 260mm, Tip cord = 160mm, sweep = 60mm. 20mm constant cord full length elevons The wing is hotwired out of EPP and then laminated with thin iron-on laminating film. The airfoil is PW51 7% thick at the root and PW51 7.5% thick at the tip. It has a 1.5 degree washout and a 45mm dihedral at the tips.  It has one 2mmCF spar glued to the bottom positioned at 40% cord. There is also a spar on the top surface biased to the rear to avoid elevon reversal. Two 9g servos are positioned vertically into slots cut on the top of the wing. The position of the servos are driven by the thickness of the wing at that part and distance from CG. The full length elevon is a tapered 3mm balsa with fiberglass lamination. ....Note I had to increase the elevon cord at the tips by 12mmto improve the control response (after the first flight trials) The fuselage is a 3mm CF rod glued onto the bottom of the wing...

Angor-Rot & Hot-Rod hotliner RC plane

 Fast, hotliner design These two are built for speed, and unlike a 3 surface (wing , tailplane and rudder) design, they are wings (delta). The thought was having the max wing area for a given wt and strength and with the least friction/profile drag, and of course ease of construction. (ignoring  difference in Induced drag). Construction is composite, foam, glass fibre, carbon fibre and vacuum bagged,  resulting  in a very strong lightweight structure for its wt. Airfoil is PW 51, with a 1.5 degree washout at the tips. Small wing tips are added to draw out the tip vortex. The LE is reinforced with CF. The wings tips and the centre section of the underbelly has some CF  reinforcements built in. It has 2 layers CF tow of different lengths acting as spar. The paint pattern has been painted directly onto the skin and then vacuum bagged. The control surface hinges are live hinges built into the glass fibre skin. The servos and push-rods are embedded with the wing. All...

DESIGN This design explores the region between a plank and a swept wing flying wing, and to try and get the best of both worlds to whatever extent possible.... The major balancing acts were being efficient across a large speed range, good C l /C d , less twist, and maintaining good flight characteristics. PLAN & DIMENSIONS A span of 1200mm was chosen to keep it a one-piece plane.  - Sweep is a very moderate 13 degrees measured at LE, and even lesser when measured at 1/4 AC line. - - Aspect ratio =- 6.3... (adequate wing loading with the set span of 1200mm span) - Taper ratio= 0.65 and Twist - (-)1 degree..... (close to elliptical lift distribution, less induced drag, while maintaining decent Re and flow characteristics at the tips, good stall characteristics) - Airfoil is PW51.. (good cl/cd, adequate +ve cm, and minimum trim losses).  - A central tailfin is chosen over wing tip fins.... (due the the less moment arm and the issues arising out of a badly designed wing tip ta...
