Torque-Tube Tail Upgrade

Sep 01, 2013 1 Comment

For several years, Align’s T-Rex 450 series has dominated the small helicopter market. Rather than resting on a proven design with excellent quality and fit, Align has gradually upgraded the heli to keep up with (or ahead of) their competitors, imitators, and outright copiers. With the release of the T-Rex 450 Pro, Align raised the [...]

Taming the Shakes: Vibration Cures

Jun 28, 2012 2 Comments

My first flight attempts with my Huey OH-6 were not successful because minor vibrations in the mechanics resonated in the scale body –particularly the T-tail—making it shake so badly it would literally eject the canopy. These vibrations had been present all along, but they weren’t a problem in the heli’s previous pod and boom incarnation. [...]

After a break to concentrate on other projects, the Osprey has moved back to the front of the project queue.  This evening’s project was to install the spindle axles that allow the nacelles to pivot from vertical to horizontal orientation and to assemble the special servos that provide power for the transition. First up is [...]

This evening’s task is assembly the frames for each nacelle.  If you’ve built a couple of non-ARF helicopters in the past there won’t be any real surprises here, but definitely follow the instructions as the Osprey doesn’t function like a normal heli. A note of clarification:  One tends to look at the nacelles in their [...]

V-22 Osprey Build Update #2

Time to start building!  Assembly of the Osprey begins with the mechanics.  Although the body is a true ARF, the mechanics have to be assembled from individual pieces.  I consider this a plus for a couple of reasons:  First and foremost, on every “pre-assembled” heli I’ve ever purchased I felt it necessary to check every [...]

RotorMast.com V-22 Osprey Build-Along

Nov 21, 2011 No Comments

One of the most impressive helicopter-related products at the 2011 Toledo Expo was the RotorMast.com V-22 Osprey.  I’d read a good deal online about this remarkable design, and I’d seen a number of online videos as well, but seeing it in person I gained a clearer understanding of the careful thought and effort that went [...]
