Rahul's RC Aircraft and other designs

 Based on Loki.. and offsprings are bigger and better 😀 It is hotwired EPS foam vacuum bagged with fiberglass, CF .. It has a 16mm UD CF tape laid on top and bottom surface acting as a built-up spar. Dimensions   Airfoil :- TL16 110% thickness Initial CG (@7% SM) is at 20cm from LE apex Highlights 1. It has a 3x1mm CF strip slotted and epoxied into the LE...  prevent dinks 2. The bottom hinged elevons also have a top mylar gap seal ...  reduce drag  3. The servos, servo horn and push rods are embedded and completely enclosed within the wing. The  push rods run through tunnels with the wing, and come out just near the TE ..... reduce drag. 4. The battery and electronics are aligned longitudinally in the center of the fuselage top. It is just a 5cm strip.... keeping maximum surface of the wing clean for lift .. and reduces drag. 5. The vertical fins are 2mm balsa , carbon fiber, fiber glass composite . They are strong/rigid, light, and thin...... less d...

  A 1500mm size thermal ePowered plank wing. Composite construction Medium AR, low WL .. Elevons moved outboard to enable inboard wing generate max lift during slow thermalling.    Dimension Sketch Airfoil BW050209 Wing area 39.43 sq dm CG @ 10% SM = 100 mm, @ 15% SM = 87 The wing was hotwired out of high density EPS (thermocole). Built-up full length CF spar. Tow width on top 18mm, bottom 24mm. The spar has a 5 x 3 mm vertical balsa compression webbing buried below the CF tow (full length).. The built-up spart is at 33% of cord. The routed 5mm groove for the vertical compression webbing visible. Also you can see the shallow trough which has been sanded for the CF tow cap of the spar. A picture of the wing core with the CF tow for the spar caps. A view of the laid out built-up spar This one shows the vertical webbing Built up spar ..all elements in position and weighed down …. awaiting for the epoxy to cure the wing with the spars in place.. is is...

 Javelin is a high aspect ratio swept flying wing. It is designed for high performance  and uses modern airfoil and construction techniques.  The planform of the wing is as above with inboard flaps and outboard elevons. It has a fuselage pod and wing tip vertical fins,  Span : 1700 mm Root and Tip cord : 175 mm Sweep : 22.5 degrees or 353mm Flaps : length 240 mm, cord 30 mm, starting 25 mm from root at the TE Elevon : length 340 mm, cord 30 mm, starting 3 mm from tip Airfoil : HS 522 standard thickness and camber. It is low drag , low Re airfoil . The details and the .dat file can be found here  https://www.aerodesign.de/english/profile/profile_s.htm#hs522 Twist : 4 degrees AUW : 840 gms  Electronics : 2212 1400kv motor, 30A esc, 9X4.8 prop, 4 x 9gm MG servos, 3s 2200mah bty. (the electronics used are more from what I have, rather than the most suited) Wing Area : 297500 sq mm, 461.13 Wing loading : 9.36 oz/sq ft, and Wing cubic loading : 5.2 CG ...
