Spektrum DX7 SE

When the original Spektrum DX7 was introduced, it was nothing short of revolutionary. Being the first full-range 2.4GHz radio, modelers from all over the world snatched them up like hotcakes. The new 2.4GHz systems offered features such as glitch free operation, eliminated the possibility of frequency conflicts, and prevented operation with the wrong model selected.

Heli Blade Balancing Tips

Most heli blades that you can buy are really hightech, and for the most part, they come balanced. No matter how much a manufacturer claims, I still like to check the balance of my blades! As a result, I trust certain manufacturers much more than others. The bottom line, though, is that I still check all my blade sets. To me, it is too important a detail not to be 100 percent sure of.

A Dauphin’s Tale – Dennis Ideue’s Stunning Coast Gaurd Search & Rescue Scale Masterpiece

One-hundred-eighty inches of carbon-fiber blades are spinning at 1,600rpm. The sound is intense as a blender filled with metal, gears and morphine. The small crowd, gathered just a few minutes ago, has now taken cover behind their cars. Little kids plug their ears. It's hard to believe this day has finally come. It's time to maiden the Dauphin.

O.S. 91HZ-R 3D Helicopter Engine With Regulator

We had a chance to review the OS HZ-91 engine with the Align T-Rex 700 last issue and found that this best of breed engine had plenty of power and ran smoothly and powerfully even when the needles were set rich. Its overall performance was more than adequate for a 90-size helicopter.

IRCHA 2009 Jamboree

The week-long 2009 International Radio Controlled Helicopter Association (IRCHA) Jamboree boasted 954 registered pilots. This is the largest pilot registration ever for IRCHA and it's said to be the largest RC event to date. Dave Millner, president of IRCHA, confirmed that the IRCHA is now the biggest event in RC history and even beats Joe Nall! Yes, Joe Nall had 820 registered pilots this year said Millner. And how about the total number of people?-not just pilots. I do not have accurate counts, but we estimate we had an extra 1,000 people on site, and double that for the night-fly fireworks, said Millner.

Getting Started

Learn to Hover

Learning to fly RC helicopters can be challenging, but if you take it methodically and avoid some of the pitfalls and mistakes that I and legions of other modelers have made, I think you'll find it to be extremely rewarding...

E-flite Blade mCX Tandem Rescue RTF

A common misconception is that tandem helicopters are difficult to fly, but the crew from E-flite has designed its mCX Blade to be easy enough for RC heli beginners with some coax (twin rotor) experience.

Graupner Augusta A-119 Koala

As the Police Chief and Mayor of the City of Lone Tree, CO, eyed my helicopter in the parking lot of the city hall, my mind whirled with possibilities: I imagined showing off the impressive turbine model at civic events, police press events and the D.A.R.E. visits that the police officers make to schools.

Gaui Flybarless E-Stabilizer GU-365

One of the coolest heli developments I have seen over the last couple of years is the advent of flybarless technology. Getting rid of the flybar and its paddles has long been a desire for the scale helicopter crowd for a more realistic appearance. On the other side of the flight line, flybarless rotor systems promise increased efficiency for the ever power-hungry 3D guys, along with the unique visual appeal. Until recently the big stumbling block for many has been the cost.

Ray’s Helitech Authoritative DVD Series

You have probably noticed that almost every article on helicopters recommends getting an expert to help check out your model and walk through your first few flights with you if you are new to the game. That is great advice, and given with the best of intentions, but what if you don't have, or can't find, a local expert? Fortunately there is an expert readily available to us all, and his name is Ray Hostetler.

One Smart Rotorcraft

The annual International Aerial Robotics Competition (IARC) held by the Association of Unmanned Vehicles Systems International (AUVSI) is a fascinating challenge. There, you'll see flying robotic platforms built by some of the brightest students in the world. The website for the competition, http://iarc.angel-strike.com notes that in the event's 18 years, the competition's set tasks have always been beyond current knowledge, and the rules say that nothing within the world military or industrial arsenal of robots will be able to complete the proposed mission at the time the [contest] guidelines are released.
