The only rule is that you should ensure you avoid pointing the transmitter antenna directly at the model.
Of course, having said that -- I was watching a guy fly FPV on the weekend and he was flying 2.5Kms away -- with the transmitter antenna pointed directly at the model and it all worked just fine (Turningy 9X with FrSky DIY).
In most cases, a decent 2.4GHz RC system has plenty of range in reserve so you shouldn't have to worry too much about where to point the transmitter antenna. I fly with mine straight out (not bent at all) but usually fly with the model to the left or the right of me -- rather than directly in front.
Remember -- if you *do* ever lose the RC link, hold your transmitter above your head with the antenna vertical -- that'll deliver optimum range. We used to have to do this back in the 1960's with our old long-wire sets from time to time.
