Advanced Single Blade Mini Helicopters 2012

more: Robbe – Nano Arrow

Robbe – Nano Arrow

From my point of view one of the best mini-sized helicopters. The package includes a switchable (mode1 & 2) controller, spare blades, 2 LiPo accus, charging station and power adapter. The sensitivity of the servos is switchable – so it is possible to fly in- and outdoors. The Nano Arrow hovers stable and it is a precise maneuverable helicopter. Flighttime is about 7 mins.
The model seems to be identical with the Nine Eagles Solo Pro.

Mini Heli can’t hoover, drifts forward or backward

It happens that your mini helicopter can’t hover in one place in the air. Instead the helicopter moves slow or faster forward or backward. In most cases this is caused by an imbalance. The cockpit is too heavy or light and the center of gravity is not in place and the main rotors don’t blow directly downwards. Toy mini helicopters often show this out-of-box.

Mini Budget Mini Single Blade Helicopters – my personal shortlist 2012

The following models from this shortlist are able to fly outdoors on calm days. They all are real 4 channel helicopters with gyroscope, fixed pitch, mini size approx. 22 cm, 2.4 Ghz remote control.

Toilet Bowl Effect

When the helicopter is flying a circle without input from the transmitter and without changing the direction of the cockpit, you experience the so-called “Toilet bowl effect”.

USB charging your mini helicopter

There are different kind of usb charging cables available. First they differ in 2 pin molex (e.g. Phantom 6010, Amewi Firestrom, …)

and the round clinker (e.g. Zoopa 150, MJX T38 [MJX 638], MJX T20 [MJX 620]) variation.

Cheap indoor 4 channel koax mini helicopters 2012

The next step would be a 4 channel mini helicopter. Still I will focus on models for indoor play and use. Keeping in mind that the requirements have developed since 3 channel coaxial helicopters it is difficult to find adequate and challenging products. Still valid are the general hints concerning the LiPo accumulators. They will increase the lifetime of all models.

There are several options for 4 channel helicopters.  The first and most easy option to build is an avatar style heli with additional motors and blades on each side.

More advanced models use a swashplate to control forward and backward flight. Like the following models:
