I have been researching the different models of AirHogs and it is quite difficult to see what they actually offer. The AirHogs site is horrible. All I have to say is infomercials and the web don’t mix. They just don’t have any information on the different models. It appears that all of the ones setup with the two props are the AeroAce model. They have a BiPlane, Jet and Diamond Aircraft look alike. I have found that the other models are no good. I tried the F-22 -Park- jet and it was not much fun. It used a weird pulse for throttle control/roll and the aerodynamics/glide were really non-existent. Estes makes a few nice models, but steer clear of the larger -Park- fliers. Stick with the ones labeled -Backyard-.
