# Can an aircraft or helicopter run into its own wake vortex?

I was recently flying my rc helicopter and I would sometimes turn it around and move it forward and sometimes I lost control of the helicopter while doing that a few times and crashed it everywhere (accidently crashed it into my poor cat). Every time I fly this helicopter it randomly starts turning to the left uncontrollably. Also I have had where I kept the thrust at the same level and then I would fly it into a different room and it would start raising in altitude uncontrollably. So can a helicopter or aircraft fly into its own wake and was it the wake of the helicopter that caused these problems with my helicopter?

• If you fly round in circles you could run into your own wake, but this isn't likely to be much of a problem with a model helicopter small enough to fly indoors. More likely you haven't trimmed the model properly, or you're flying it out of line-of-site - some of these models use infra-red and not radio. Or maybe you just need more practice.

• Also, the very small size makes it very susceptable to air currents. A blowing vent, a fan on an electronic piece of equipment, or just air convection could cause something like fly it into a different room at it would start raising in altitude uncontrollably.

• Late but a roll to one side during high speed flight might be retreating blade stall, but from the info in the question does not sound likely. Jan 30 '19 at 10:58
