I recently had the pleasure of reviewing the Blade 600X, and I have found it to be the best-engineered 600-class heli I personally have flown.  The quality of construction is outstanding, the drivetrain is extremely stout, and handling is silky-smooth.  I look forward to getting a lot more flying time on this bird.  (See my full [...]

Review: Savöx Brushless Motors

Jan 08, 2014 No Comments

Savöx is well-known to modelers, particularly in the helicopter world, for their powerful digital servos.  What you may not know is that they also market a line of brushless motors for electric helis.  These motors span all popular classes from 450 to 700 size, and their quality of construction is excellent.   The 450, 500 and [...]

Flight Tested: Heli-Max UH-60 Black Hawk & EC145 Eurocopter

Jan 06, 2014 1 Comment

High-quality micro helis are everywhere these days, and with so many on the market, it’s hard to keep up with them all. That said, scale is my first love, so Heli-Max really caught my eye with two highly detailed models in 1/43 scale. The first is a Eurocopter EC145 and the second is an even [...]

Gyro Programming 101

Dec 12, 2013 No Comments

Many low-time heli flyers making the step from Bind-N-Fly micros to larger helis struggle with programming heading hold gyros. The following is a general guide for programming gyros. It’s not intended to address the much more aggressive setups needed for full-on 3D, rather the goal is to program a typical gyro for sport flying. Because [...]

LET’S GET ORGANIZED!

Nov 25, 2013 No Comments

Electric helicopters are great, but one challenge is the need to stock and keep organized a wide variety of spare parts. As a scale guy and scratch builder, it’s even worse for me because obsolete or damaged parts that most flyers would toss become potential raw material for some future project. I spend about 150 [...]

Home-brewed Quads

Nov 25, 2013 No Comments

 I’ll admit that multi-rotors haven’t really been my thing. I’m not heavily into aerial photography, and helicopters are just more interesting to me. I do get a kick out of the remarkable work some of the AP wizards have produced, particularly Gary Graf’s amazing flight videos (see Gary’s YouTube channel, FPVFlightSchool, for some examples of [...]

Preventive Maintenance

Nov 14, 2013 1 Comment

Electric helicopters are far cleaner and smoother running than their nitro-powered brethren, meaning that they tend to require less maintenance. This, however, can be both a blessing and a curse. I’ll confess to being a bit haphazard with preventative maintenance on my helis, with an inclination to think, “It flew fine last time As my [...]

Electric Power & Performance Advice

Aug 20, 2013 No Comments

For power-hungry 3D applications and heavier scale machines, is it better to generate the required watts with more amps or with higher volts? Let’s look at some real-world examples and see what’s going on behind the curtain. JOULE’S LAW The crux of the problem for high-current power systems is that power losses increase with the [...]
