Thanks @Ravi_maker

I have build same plane
Material used:
1. Thermocol density 24-26
2. Fevicol mixed with water.
3. butter paper.
4. jhaadu ki teeli for giving curve to wings (idea by K K Iyer sir)
5. Ice cream sticks as you said on call.
6. Baansh sticks.
7. Hot glue gun.

Time : more than a week to build this plane.

Problem with app Error: Unfortunately, wifiplane has stopped(this error comes in kitkat and other mobiles. App only worked in Android Nougat). Please fix this error.

I can't get speed as well as height because of weight of plane and 650mah battery instead of 180mah.
Plane can fly at 70-80 throttle.
Now, I know value of depron foam.

I charged battery and go for flying. Reality is totally different. Still remaining voltage is 4.01. There is many take off and worst landing and total time is more than 5 minutes.

I can't share video because i don't have extra mobile.

Now i want to build flying wing. Share plans of flying wing with me.

wifiplane app is not working in lower version of android. App is only working in nougat.
For flying plane, I need android phone with nougat. Now, i am dependent on my friend for a phone.
No one will buy new smartphone for one app. There is no use of your idea and project without working app.
You aren't responding to my calls and response is always "busy" which means you have added my number in blacklist.
Send Source code of app on my email. So, i will make changes in app So, app can work in KitKat.
I hope you will understand.
