Well I have that hobby of RC model airplanes and have two of them : A high wing traner and a low wing aerobatic plane.Had both planes shipped to me via US Postal Service back in 2005. Similar planes are now available in local market through specific shops. Dont go for cheap chinese toys, they wont work and will let you down.
I learnt to fly RC planes from Mr Razzaq who is trainer at Islamabad RC club at F 9 park. However many members may be willing to help you out for free. I am not into helis but some members do have RC helis and can give you good advice. Do visit F-9 Park ( sats and sun )from sector F-8/1 direction through an approach road starting from a local Maddrassa.
There are three authentic shops from where you can get Helis as well as gas or electric powered planes. One is at F-8 markaz and the other is in Saddar. There is also a good shop at Lahore by the name of hobby lobby. Contacts are as under :-
1. Mr Razzaq : 03335320848
2. Hobby Trac, Isb: 03215359598 , 051-2851806
3. Fly and Spy, Rwp : 051-5513551, 03009554637
4. Hobby Lobby, Lhr :03009478249, 042728840
Just remember the toy hels or planes under Rs 10,000/- are unreliable and a waste of money. Besides you cannot fly without proper training. If you have further questions feel free to contact me.
