I need a complete plan + equipment specifications to create an indoor plane which my 10 year old daughter can fly
I want her to create the complete thing herself
The plane must have propeller in the middle position and must cost very less

I am ready to pay for this service, if any one can

Hi Gaurav,

I recently built a micro slow indoor flier. You can refer to the details:

http://www.rcindia.org/electric-planes/my-attempt-to-build-a-micro-slow-flyer!/

Also you can refer to the post 'Night Vapour clone' from arun.sreelakam mentioned in the above post. That was a nice built slow indoor flier.

But both the above micros have prop in the front

Also you can search in the forum. There are different other posts which might fit your criteria!

Happy flying! 

if you want a good rubber band powered plane, check out the guillows balsa kit's...if i am not wrong, someone on the forum itself is selling it for around 200-250/- i have a few of those, they are awesome... mine could stay in the air for about 2 minutes....

hope this helps
