SU 35 with Thrust Vectoring

-
Pictures and build highlights of a SU 35

The plan printed on a A4 paper. The whole design was based around a 9"  space for prop (mid mounted). With that as the base, the conversion ratio was 1cm on plan was 5.88 cm actual. The total span was 95.1 cm or 37" and the length was 114.6 cm or 45"

The above dimensions were drawn on a scrap newspaper and templates cut out or traced directly on 5mm foamboard. 
Note the Increased dimensions of the wing and tailplane. 

few pictures of the construction

The front fuse was made out of 5mm foamboard sides with a eps turtledeck


The nose was shaped  out of  eps foam.


Below is picture of the elevator mount. The elevator was full moving elevator. It hinges on a 3.5mm CF rotating on a 2.5" al tube. The CF was wrapped around with clear tape to mage a snug fit


The wing had a leading edge droop which was reinforced with two chordwise stakes in each wing
Note the beveling of the TE of both the wing and elevators

The thrust vectoring is only in pitch through two paddles which move in unison, and linked to one servo




Some more views of the whole aircraft




I would be using a 9XR tx with a ER9X software .. ailerons and elevator (ch1&6), elevators (ch 1&7), Thrust vectoring (ch 5), Rudder (ch 4)

Weight of unpainted aircraft with all electronics without bty = 450 gms or around 610-650 gms with bty (depending of size 1800mah or 2200 mah)


Final version : NTM 2836 1800 Kv motor, 40 amp esc, 7X4.5 prop, 2200mah 3S, AUW 750gms





in the first flight the CG was a bit behind.. finally after testing the  CG was set about 2 cm behind the place where the lerex joins the wing

The aircraft flew well, and could hover, the rolls were very snappy. With thrust vectoring it could do kulbit and can rotate in a dime

A photo of it with my son.. gives an idea of the size... (the other aircraft is a newly built F18)


Some more pics of the plane.. it is plane with lots of flight time.. and well aged (nics, dents, cracks)  like battle scars









A flight video of it doing maneuvers including the pivot yaw turn is here

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

-
Image
 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...
