the wind will affect the heli a great deal unfortunatly,the smaller the heli the worse it will be.the worst problem will be that the wind will try to blow the tail round on you,however if you have a good heading lock gyro then that won't cause you a problem because the gyro will compensate for it and will generally make it easier to learn to hover.even so,the wind will generally blow the heli around making it climb and decend when you don't want it to,you have to compensate for this when flying.generally speaking you should wait for calm days when learning to hover.also the wind will make the heli hard to land aswell because it keeps the machine up in the air when you reduce the pitch,and again you have to compensate by putting more negative onto the blades to land the heli
