In my experience there is no way any 1/2A will keep 52 foot lines tight. Even the TeeDee powered stunt models only ever flew on 35 to 40 foot lines IIRC. And this is just a simple trainer. Even if it did fly OK in level flight any wind at all and it would come in on the lines. Similarly if you climb very high at all the model will come in on the lines. I suppose if you made a special model that used 30 degrees or so of out thrust it could be done but it would take a VERY special sort of model I suspect.

Fishing WIRE does not come that thin but the new non stretch Spectra or Spider line does. Look for the 6 lbs test line that is sized as per the old 2 lb monofilament. That line is tough enough for 1/2A and will let you fly on 30 to 35 foot lines. And another advantage of this synthetic stuff is that it won't kink. 008 metal lines tend to kink very easily. One forgetful step and snag and the lines are ruined. IMHO they are just not worth the advantages for general flying and training.

Like clscale said, once you start flying and concentrating on the model you won't get dizzy as easily. But it also helps to train yourself to not focus on the background. It also gets better with time on the handle as your mind and balance gets used to the turning. Trying to get that feel without an airplane is difficult.

Good luck with your first flights.
