Welcome to the forums Anas...
I shall not echo what has already been mentioned by Atan and AZRC... however i have some inquiries about yourself...
Are you going to be an expat working in Brunei? or just for a social visit?
If you are an expat, then do take note about the regulations w.r.t importation of radio equipment and licensing. If you are bringing it with you as accompanied luggage though the airport, then if you are not lucky and get inspected by customs, then it may be confiscated. This also applies to Aircrafts with powerplant i.e. Engines/motors/ etc. Only bare aircrafts i.e. unassembled kits/ARFs can be imported without a license. The best route would be to bring via your trunk which is seafreighted.
We (RCAB) are working our best to ensure proper legislation in place so that these restrictions can be managed and controlled.
If you are in the vicinity of Bandar Seri Begawan, you may contact me at +673 817 5561. We can provide you with directions to the field.
