 This is a 1600mm high performance powered glider... composite construction





Dimensions


The wing is hotwired from EPS with airfoils as  AG34 : AG35 : AG36

The wings, tailplane and vertical plane are foam , fiberglass, carbon fibre composites which are vacuum bagged. 

The wing is one piece with full length built up CF tow spar. and live fiberglass hinge for flaps and ailerons. It also has LE and TE CF tow reinforcements and also CF cloth reinforcement where the servos are mounted.

The horizontal and vertical tail surfaces also have full length built up CF tow spar and well as LE and TE reinforcements.

The fuselage is pod and boom. The pod is balsa, fiberglass composite with carbon fifer reinforcements at certain places. The boom is tapered CF tube.  

The wing is mated to the fuselage with 2 x 10mm nylon bolts and nut. It can taken out for transportation and storage. 

Electronics 

2217 1000kv motor, 30A esc, 6 x 9gm micro servos, 2200 mah 3S bty

AUW - 815 gms







Flights

Test flight was done with a 2212 980kv motor with a 11" folding prop.. It was underpowered, primarily due to the quality of prop, as flights with a 10" fixed prop was better. .. 

Latter the motor was upgraded to 2217 1000kv with a modified 11" prop . This power combination was much better.. more thrust and ran cooler.. and also bettered the glide with the prop folded.

Turbulator strips were added at the tips to better control tip stalls 

Flying CG is 95mm from wing LE at root

It has a extremely good glide ratio.. and also decently fast. Turning radius is ok (could have been better... some dihedral would have been good).. but is able to ride a decent sized thermal... I use airbrakes (flaps at 35 degrees) to land in the decent sized field.. without the brakes it will overshoot. Visibly is an issue (the  pic below) ... Will try and get some better pictures.



Unfortunately it crashed.. I was using a homemade folding prop (normal prop converted to a folding prop).. one of the blades broke off in mid flight  causing massive imbalance, which resulted in the whole motor mount to break off ..

Flipper - Plank flying wing SAL

Image
 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...
