For Long wanted to Build big Flying wing, which will fly gently, stable and can ride on thermals.......

so decided to go for 50" flying wing....then Praddy gave me idea of making ALULA instead of traditional flying wing....and i like this bird...

it has slightly forward swept and dihedral of around 1 degree.......

Decided to make own plan..downloaded few pics from original website and some forum and started creating Vector drawing in CorelDraw.......after completing took print out in A4 size, stick  it together and cut the main wing.

Decided to make KF2 airfoil.. main wing was cut in 8 mm Biofoam, KF2 step airfoil in 5mm and control surfaces in 5mm.

planning to keep it as light as possible...so planning to use 2208, 1800 kV motor with may be 1000mAh 2s Lipo and 7" prop.. power system is not yet finalized...will have to experiment....motor will be mounted in the front in puller config..

here are few pics

Good going Ashish, cant wait to see this baby fly

will definatly try to complete this till weekend  . so that we can maiden it on sunday...may be u will have to launch it for me  ...and of course dont break it....

over the weekend was able to make removable rudder, control surfaces and able to mount servo.....

to make rudder detachable, i used 2 cm long, 5x3 mm hollow Cf pipe and fixed it on the fuse, and used 3 mm CF rod in the Rudder so that it can be easily inserted/attached to fuse..here are few pics

Control Surfaces attached with CA hinges and Evotite

Servos and Horns mounted

Nice build Ash!! The detachable fin is good. Did you consider Nylon bolts instead of CF Rods ? you can get M4/M6 bolts long as 2 inches.

Superb Build Ashish!!!!!
yet another model with perfection.

That looks like a good slope soarer
Isn't the original design supposed to be a sloper or a combat wing ?

@Ujjwaana,
thanks yaar, i was also thinking same, it was better option but would have taken more time in getting it so thought of completing it with CF tube and rod

@xantos,
original design is a soarer, but thought of putting little power to it...lets see how it fly...

Cheers
Ashish

which type connectors are you using for servo (seems like snap on), i have never used thats why asking .

what is the motor specification and battery you will be using

waiting for the maiden

Finally completed and was able to maiden it on sunday....

thanks to Praddy and SLS...to successfully maiden it...test pilot was praddy and launcher was SLS...

initially used CF 2805/1600, with 6" prop and 2s 1000mAh battery to keep setup light.

but during maiden we realise than it is just able to fly level....so changed setup to 2208/1800 motor with 6" prop and 3s 1000mAh battery..and wow it started climbing pretty decent.....

it was really wonderful day.. praddy, SLS and me enjoyed flying this bird... it was gentle....pretty stable.....

unfortunatly i forgot my camera so video this time..but next time will surely do it...

now planning to upgrade it with folding prop and to build canopy to reduce drag...

here are few pics

cheerss

HI vineet,

servo connectors are standerd one, JR type.

motor is 2208/1800 kv, battery used is 3s 1000mAh

where can we get Depron or any other type of foam in pune.. the exact shop location would really help...n whats the approx cost of sheet(also please tell the std size we get)... thanx in advance.. 

It is called Biofoam here in Pune as well as mumbai...it is available in number of shops at Bohari Lane at tulsibaug and also in Aundh

cost is around 5mm: Rs 60-70, 10 mm: Rs 125. these prices are amost 1.5 times that are in mumbai!!!!

Finally got chance to take some videos on sunday, thanks to AMint (SLS) and prady  !!!!
