RC Helicopters

Electronic RC helicopters are simpler and easier to maintain than their nitro counterpart. Less parts also means makes it possible to make smaller scale models. Battery longevity has never been better with the latest Lithium Polymer (LiPo) technology.

T-Rex 250

T-Rex 600 - 500 - 450 - 250

This is a new 200 series micro-helicopter from Align, announced in late 2008. Engineered to the quality expected for a T-Rex. There were a few initial problems with the tail but it was quickly handled and fix with a new metal replacement.

The build requires extra attention to details and precision when setting up the links, angles, aligning, and leveling due to the small scale of the helicopter.
