One of the most challenging individual maneuvers to fly cleanly is the snap roll. It also happens to be one of the most misunderstood of the different aerobatic elements. Also known as a “flick” roll in European aerobatic circles, the snap roll shares more with the traditional spin than the conventional aileron roll. Snap and spin maneuvers share an autorotation about the roll and yaw axis caused by a stalled wing and a yaw input. Both aileron and snap rolls rotate the aircraft through 360 degrees, but that is where the similarities end. The important difference is that conventional rolls are primarily an aileron maneuver flown at a relatively low angle of attack, while snap rolls are a rudder/elevator maneuver at a very high angle of attack.

In my 19 years of flying fullsize aircraft, I have flown three types of Cessna 182s: a squaretail model from 1958; a swept verticalfn model from the mid '70s and an R182 Skylane RG with retractable gear. All three were very stable and had a lot more get-up-and-go than the 172s I had flown. I always thought the 182 was a great airplane (even though it has a nosewheel) and would make a great RC model. Parkflyers.com has turned that thought into a reality with its nicely done, sport-scale Cessna 182 500-class brushless model.
