Flight Technique: Cobra with 1/2 Rolls

Apr 01, 2015 1 Comment

If you follow full-scale aerobatics, there is another maneuver that goes by a similar name, but it is called the Pugachev Cobra. The Pugachev Cobra shows post-stall maneuvering as it displays an abrupt pitch change and a high angle of attack. The Pugachev Cobra is very similar to the common “3D” maneuver, the “Wall,” where [...]

Multi-Servo Control Surface Setup Made Easy

Apr 15, 2014 1 Comment

With many of today’s giant scale aerobatic aircraft multiple servos are often used to move each flight control surface. Modern computer radios actually have specialized menus to help setup and adjust multi-servo installations, but you can do it the old fashion way as well by using programmable mixes. Basically you setup a two servo setup (for ailerons [...]

Fly this updated loop!

Jan 15, 2014 1 Comment

Even though this maneuver is intended for indoor precision aerobatic competition, the setup process for both an indoor aircraft and an outdoor park flyer are similar. Flying indoors usually requires more control surface deflection due to the obstacles that exist, which is acceptable for a 4.5-ounce foamie. (Photo by Xavier Mouraux)   Since we are [...]

Hot move: negative snap from inverted climb

May 09, 2013 No Comments

For this maneuver, the pilot enters from inverted flight and pushes to establish a 45-degree climb then he performs 1½ negative snaps. After the snap, another line segment (equal to the first line) is then executed. Once the maneuver is complete, the pilot must pull 135-degrees to exit in inverted straight and level flight. This [...]

  Overview of the reverse Cuban-8 with half rolls. Illustration by FX Models When I first started aerobatic competition, symmetrical maneuvers that combined various elements were of the most complex to perform both precisely and consistently. Let’s take the loop, for example. While it may be fairly straightforward to perform a single loop, try flying [...]

Gasoline Engine Adjustments

Dec 14, 2011 2 Comments

  Behind every great flying airplane is a reliable engine with a smooth transition. To obtain this, you may have to spend some time tweaking the High and Low End needles that can be found on the carburetor. Personally, I always start with the factory recommended settings and run the engine first to see if [...]

Master the Stall Turn Thrust-Line Setup

Oct 21, 2011 4 Comments

Before you attempt the stall turn, take a moment to ensure that the motor thrust is properly set on your aircraft. Sometimes, manufacturers build what is called “right thrust” into the aircraft’s motor box. When you view your model from above, the spinner and propeller should be on the fuselage’s centerline, but the propeller may [...]

5 Easy Steps To Flying The Knife-Edge Spin

Sep 08, 2011 No Comments

In my opinion, the knife-edge spin is one of the most impressive extreme aerobatic maneuvers. It’s very demanding for the pilot and the airframe. First, I’ll describe the maneuver. In traditional knife-edge, the aircraft is rolled approximately 90 degrees from upright level flight. Then altitude is sustained by using top rudder. When the maneuver is [...]
