Fly a reverse Cuban-8 with half rolls

Oct 01, 2012 3 Comments

  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 [...]

Let’s Talk Fuel Lines!

Aug 23, 2011 2 Comments

On all of my nitro and gasoline-powered airplanes, I use zip ties to secure my fuel lines going from the fuel tank to both the carburetor and the muffler. When routing lines within your airplane, make sure that they can move freely and are not bent in any odd fashion. After all, you need to [...]

The Need for Tail Bracing

Jun 02, 2011 No Comments

Some aircraft have built-up tail surfaces, which need tail bracing wire. The AMR 42% Super Decathlon shown in the photo, has a built up tail like the full-scale Super Decathlon, and tail bracing is needed! First, check with the instruction manual of your aircraft if tail bracing is needed. Otherwise, if you feel that there [...]

Ignition and Electrical Component Safety!

Jun 02, 2011 3 Comments

When I build an airplane, I always spend extra time to ensure that all internal components are installed properly and well-secured, whether I am building a .25-size glow-powered model, or a 170cc giant-scale aerobat! This time, we will take a look at my ignition installation on my 2.6m Composite-ARF Edge 540. This is an all-composite [...]

Control Surface Deflection Accuracy

May 16, 2011 No Comments

In my 22 years of flying radio-control airplanes, I have learned that time must be taken when both building and setting up your aircraft. For example, let’s talk about control surface deflections. Over the years, I’ve seen some cases at the flying field where pilots simply “eyeball” various control rates and often blame their aircraft [...]
