Qatar has only one official RC field for airplanes and helis, close to the city of Al-Khor, located at about a 30 minutes ride by car from Doha.
The rough directions are as follows...
From Doha, go on the highway that takes you to Shamal/Ruwais (the highway that starts from the Landmark Mall). About 28 kms on this road (from Landmark), you will see the junction where the road to Al-Khor city (and Ras Laffan) hits the road you are travelling on. Continue straight on the same road (do not turn right into Al-Khor city) for about 6.5 kms, and you will see a tall telecom tower standing alone on the left side of the road (do not confuse this with the many smaller towers of power transmission lines one kilometer earlier on the road). One more kilometer after you see the telecom tower, you will see a nice plantation on your left with people working the vegetable fields (There are many plantations there, this is kind of unique in that there are lots of cabbages/lettuce being grown and tall trees towards the back, unlike the other farms that have just date palms). You have to exit the highway to your left, as if to enter the plantation (be careful about on-coming traffic). There is a small opening in the guard-rails there, and a some-what steep incline that will take you into the plantation. As soon as you come down the incline into the non-paved track, turn left again (which means you do NOT enter the plantation), and follow the boldest tyre marks, keeping in mind the map given below. Basically, you go around the plantation to the back side of it, past what seems to a deserted single storey house on your left side, and further into the wilderness. The entrance to the field is towards the back of the field (south side), which is really confusing for first-timers.
