Hi every one, I am from Bangladesh. In Bangladesh I don't get any stuff like brashless motor, speed controler, tx & rx anithing.  Any body can help to get these stuffs. I would be grateful.
Thank you 

Not sure how difficult it is for you to get items shipped in via regular postal service in your country.  If that is not a problem in general (no items getting lost, customs official not causing undue trouble etc), then you can order from online stores with any credit card or even bank payment transfer.  http://www.hobbyking.com is a common one, there are even some Indian stores that ship outside India. 

The other option is the more expensive courier/parcel companies like UPS/Fedex etc, again not sure how much coverage they have in Bangladesh.

Please tell us more about how the whole shipping of parcels from outside Bangladesh to inside works.
