https://www.instructables.com/id/WIFI-CONTROLLED-RC-PLANE/
This plane is very low cost to build... Its very slow flying.. best suitable for kids and beginners...
Need your suggestions for improvement...

@Ravi_Maker
I am interested in making this type of rc plane & other kinds of diy thing but problem is of design.
Autocad is very heavy software So, i don't want to use.
Please provide designs for this type of plane in pdf file or image if possible.
I want to know wingspan & chord length rudder  elevator other details.
I am waiting for your reply.
Thanks.

CAD Tool is just used to visulize design in 3D.. Its not used to fabricate the plane.. So don't worry about CAD Design..
As mentioned in my blog,
PDF plan I don't have yet nor it will needed, if you do minor changes in design than also plane will fly with different trim setting on field.. Have a look at two different rough design plan with same electronics, motors, props and battery in following videos..




Thanks,
Ravi

Quite stable for such a small wingspan. 

Can we use A0SHB mosfet instead of A2sHB mosfet

Congratulations. Simple design and small field flyer. Nice catch too.
