sanjay sir..the motor is not just held by the cable ties...there are three screws firmly holding the motor to the bar...I used the cable ties just because I could not align the four screw and the hole...

Santhosh is that 24gm motor produce enough thrust?
The wings looks heavy :(

You are right ..arun but the  motor is specified as 400g thrust with a 8 x 4 prop...
Keeping my fingers crossed for the test...
I will update about AUW ....
I thought that the wing will act like as that in a glider...
If this motor will not work...I will replace it with my 3536 1250kV 500W motor..

That is fine another option is make another wing and use a smaller lipo with same motor...

Ok Arun,, Let me try all the combos .. 2s / 3s , 24gm motor./ 500w motor , new wing /old wing....and find out the correct combo..

Santosh, why don't you try the old formula - 75~100 Watts per pound of weight, and see where it gets you? Decide the prop, and then on the basis of these 2 figures, select a motor

sanjay sir , I am expecting  a AUW of 700gm with a 2S 1000mAh and 800gm with 3S 2200mAh....
As I have seen this wing producing a lot of lift for my 1.5Kg previous coro model ,I thought that eventhough the motor is underpowered  for this plane the wing may produce some decent lift..is it correct?

BTW the power of this motor is 85watts...you are right ,I need to get a new motor / reduce the weight of the plane right?

What is your motor KV & what prop are you planning

AUW of 800 gms => 85 W is OK

Lift will also depend on the angle of incidence

I think it will be underpowered. Thrust is not enough, and with 2S, you have max wattage of about 50 W, in actual running about 30~35 W, with 3 S about 80 W max, actual running about 50 W
