Development of the Hangar 9 Ultimate Biplane, Designer Mike McConville Shares his thoughts.

Jul 09, 2012 1 Comment

While putting together the October 2012 “Let’s Talk Giant Scale” column discussing Flying Wires and Wing Struts, columnist John Glezellis discussed the need for functional rigging with RC aircraft designer, Mike McConville.  Mike developed the very popular Hangar 9 Ultimate biplane which, unlike most biplanes, doesn’t require flying wires. Let’s see what Mike did during [...]

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 [...]

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 [...]

Linkage Safety

May 23, 2011 No Comments

Now, let’s talk about proper linkage setup. Many advanced airplanes take advantage of ball-links to attach given pushrods to a servo arm, control horn, etc. Using ball-links in these areas guarantees to improve linkage geometry and allows a given surface to move freely.  While using a clevis works if servo and linkage geometry are correct, [...]

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 [...]

Safety First: Electric Airplanes

May 09, 2011 No Comments

Safety First: Electric Airplanes Nowadays, it is quite common to see many different electric airplanes at the local flying field, and with their increase in popularity, I would like to discuss safety. On my electric powered models, I use a feature called “Throttle Cut”. With the flip of a switch, the motor can become deactivated. [...]
