Gaui X7 Competition 3D Helicopter

Competition Quality, Flybarless 3D Helicopter When I first saw the prototype X7 at the 2011 3D Masters, I wasn’t sure what to think about it. At that time, the model was still being developed. Around May 2012, the X7 was …

Rotormast V-22 Osprey – Part I

I was a Marine in the 70s, and had the good fortune to be assigned as an Avionics technician on the AV8A Harrier. I was responsible for the maintenance and repair of the "Autostab system" which while not officially an autopilot, was there to help the pilot maintain safe hovering flight. As a result, any modern model that can transition from hover to forward flight, (and back), is going to get my total attention! Not to mention that the V-22 is the current state of the art deployment method for Marines in the field. This model was a must for my interests and passions!

Rotormast V-22 Osprey – Part II

V-22 Osprey model produced by Mr. Tom Mast is the only one in the world that I am aware of which can successfully hover, perform transitional flight with the rotor nacelle angle at different tilt angles and convert into airplane mode for forward flight. Tom Mast invested four years into the engineering and testing his V-22 scale model and then formed Rotormast, LLC to distribute this machine. Tom's knowledge of tilt rotors comes from his career as an engineer at Bell Helicopter in Texas, where the full-size V-22 is designed and built.

Rotormast V-22 Osprey – Part III

The V22 Osprey model produced by Mr. Tom Mast is the only one in the world I am aware of which can successfully hover, perform conversion flight with the rotor nacelle at different tilt angles, and then convert into airplane mode for forward flight. Tom is very knowledgeable about tilt-rotors because he is also an engineer at Bell Helicopter in Texas, where the full-size V22 is designed and built.

Force RC Combat Helis

Sunset is fast approaching and the night air is still. I am behind the controls of a military helicopter patrolling the air around our satellite base station. An uneasy feeling comes over me, putting me on high alert. As I hover past my base station again, “BAM!” I am suddenly hit out of nowhere and my heli spins out of control.

Futaba CGY750

I could sum up this product in one sentence. The new CGY750 3-Axis Gyro System coupled with the built-in engine governor is simply incredible; try it and you will love it.

O.S. Engines 55HZ-R

The HZ-R shares the exact same specs as the popular 55HZ-H but adds the OS Demand Regulator System (DRS) at the fuel inlet to supply fuel based upon the engine RPM. The DRS uses crankcase pressure coupled with a check valve to pressurize the fuel supply creating a high-pressure system that provides constant supply of fuel, unlike like fuel systems that utilize muffler pressure that change as the tank drains.

Skookum Robotics SK-720

There are many flybarless controllers on the market now, and most have evolved to the point where they all fly well for most pilots. In addition to flight performance, other differentiating qualities that separate the various flybarless controllers are the ease of setup and the features that are available. The SK-720, from Skookum Robotics, is a second generation flybarless controller and is one of the most feature packed controllers that I’ve seen, while still being relatively easy to program. Let’s take a look at what it has to offer.

Thunder Tiger Titan X50

I have been a fan of Thunder Tiger helicopters for almost 10 years, having owned several “Raptor” series helis. Opening the box of the Titan X50, I guess I was expecting some of the same style mechanics that have been synonymous with Thunder Tiger helis of the past. As I looked through the kit, I had to do a double take to make sure it was, in fact, a Thunder Tiger heli, as this machine bears no resemblance to the Raptors of the past. In fact, this might be what a Raptor would look like if you upgraded every part on the machine.

Align T-Rex 500E

Align has become the behemoth of RC heli manufacturers, encompassing a full line of helicopters from the tiny Align 100, to the huge Align 700E. The Align 500E sits right in the middle of the size spectrum, sporting 425mm long blades, and having a weight that is roughly double that of a 450-size helicopter.

Vario Helicopter’s Aerospatiale SA 315B Lama

Once in a while, a model comes across our desks that words cannot describe. Such was the case with Gonzalo Martinez’s ¼-scale Aérospatiale SA 315B Lama from Vario; when we saw the photos and the level of detail in the building process, we agreed that the photos spoke for themselves. So, feast your eyes on the next six pages and imagine what it was like to build this masterpiece.

Thunder Tiger Mini Titan V2

When I first unboxed the kit, I figured I was going to be building yet another good 450 heli, same as usual. Well, this isn’t the typical 450 kit and I did find some interesting differences, some of which include a full CNC aluminum-alloy metal head and arm, a carbon fiber-encased tail, belt drive and motor, an ESC and a BEC. Don’t worry, there is a lot more coming.
