Product Description

Product Description

Be warned. This is no ordinary radio controlled helicopter. This is the TandemZ. A full three channel, auto stable system with twin propellers and an advanced multi-role set-up that requires skill, brains and determination to master. In appearance, the TandemZ closely resembles the iconic Sea Knight Helicopter, a vehicle famed for its assault transportation of combat troops and its ability to land on aircraft carriers. The twin propeller system is a striking feature of this unique style of helicopter, and providing greater stability, greater control and added power when airborne. With the TandemZ being a full 3 channel radio controlled unit, users are able to control the flight altitude, forwards and backwards movement and the direction of flight. Easier said than done. The handheld control unit (which doubles as the charging base for the TandemZ) is more complex than the standard R/C chopper, incorporating controls for Yaw trimming (direction), Pitch trimming (hovering angle), Throttle (altitude), Direction (forward/backward movement) and an additional headlight switch for flying in the dark. With guidance from the instruction booklet and a little practice, users will quickly appreciate the added control that the TandemZ offers and once mastered, can attempt more challenging stunts than ever before.

Manufacturer's Description

Silverlit, the brand known for its tiny radio controlled Picoo Z indoor helicopter, brings you the Tandem Z -- a remote control helicopter with twin rotors just like a real Chinook. Stabilised by a sophisticated gyroscopic stability system, with proportional throttle for precise control, the Tandem Z represents an outstanding technological achievement for a model this small.

The helicopter has wide infrared control, a built-in Li-Poly battery, trim control and rigid foam body. It also has a unique roto-blade system for steady take off and, unlike the original Picoo Z, it's a three-channel helicopter (forwards and backwards, left and right, up and down). A normal charge of 20-25 minutes should give you a flight time of around 10 minutes, and charging is done directly from the remote control (which requires 6xAA batteries).

This is a logical evolution of the original single-rotor Picoo Z, which set a new standard for remote control helicopter price/preformance. Its design is a fascinating departure from conventional solutions, and has great educational merit.

With helicopters, performance means stability, not speed. It is said that aeroplanes want to fly, helicopters want to fall..... And that is doubly true of models, which are much twitchier than bigger ones.

Full-scale twin-rotor machines like the military Chinook demonstrate much improved pitch stability over ordinary single-rotors, and the twin-rotor Picoo benefits from this. If you have tried the single-rotor Picoo-Z and found it a bit lively, this is much more stable and easier to fly, especially for beginners. There are also some clear fins (not shown on the illustrations) which increase the damping in yaw, so that the aircraft is less nervous when turning. The fins also help with anti-torque. Nice one.

Chinooks use contra-rotation to cancel the torque from the engine - front rotor turns one way and the back one turns opposite so the helo does not spin around. No need for a Sikorsky-style tail rotor.

But this 2-rotor Picoo uses a novel approach - both rotors turn the same way and appear to be identical to the rotors on our 1-rotor Picoos. That ensures that spares are available and will have saved a few bob developing a rotor that turns the other way. So to stop it spinning they have leaned the front rotor to one side, the back rotor to t'other side. Clever.

This cancels the torque quite effectively, and the 'rudder' control tilts the front rotor assembly left and right in order to steer.

Having owned 3 PicooZ helicopters, I thought I ought to give the TandemZ a try. It's more versatile than the PicooZ in terms of control, although trickier to master. I found that in a small room, it's easier to control forward motion using the forward/backward trim than with the joystick. The experience is somewhat more exciting for the addition of forward motion to this model; whereas the PicooZ kind of randomly hovers forward, the TandemZ zips around the room. Expect more extreme crashes when it goes wrong!

I bought this as a birthday present for my husband and have had great fun watching him trying to master the art of flying!! We've both been amazed at how the helicopter has stood up to the number of crash landings and bouncing off walls and ceilings. Now he's getting the hang of flying it's been quite interesting to see how the helicopter works and responds to the controls, such as hovering for instance.
Highly recommended; in fact, it looks like his work mates are starting to drop hints to partners ready for Christmas.....

Hello again,

here's my early review of the TandemZ twin rotor Sea knight/Chinook from Picoo.

As with the first report I would qualify the various star ratings ive given with further detail but since ive done this already in the PicooZ Metro City and they remain the same- just have a look at the first bit of that one for further explination.

As with the first, if you want a quick snapshot review here it is:-

Great fun, more visually imposing, louder and powerful than the PizooZ chopper but much less forgiving thrust/lift when your not on your game. Easier to point and shoot when the trim is sorted out. A longer learning curve involved to master and expect more catastrophic crashes while you get to grips with it but that's why you want one isn't it?

Ok, so I got the PicooZ Metro City a couple of days ago and i'm clearly no master pilot but what follows is the thoughts of someone who's had 24 hours with a Tandem and 72 with a PicooZ.

Hardware- the 'copter you know all about if youve read the other reviews here so i'll just add a bit about the RC unit. Instead of a single trim toggle just under the direction(right hand) stick as with the PicooZ we get two seperate trims in the form of circular dials which are positioned to fall naturally under your index fingers when you hold the unit. This means you dont have to remove your right thumb from the right stick to trim the 'copter- just dial in your trim and away you go. The left trim controls static pitch - i.

After getting my father the helicopter I soon decided to get one my self, but since I found it hard to fly accurately so I decided to purchase the Tandem as its twin blades indicated better control.

Default flying
Helicopter - Circling or forward (I found forward difficult to achieve and too fast to avoid all objects)
Tandem - After mastering the two trims (which need occasional readjusting) I have achieve a near perfect hover, though most times I found a genital spin or forward momentum preferred for flight

Steering
Helicopter - I found I could achieve my desired direction rarely and only through changing the circles it spun in. Most times I hit walls before I got to my desired location. Fun but high failure rate
Tandem - From a hover I could turn in my desired direction and then press forward. I also found mid air movement more accurate where I could usually turn correctly first time. However there is a transfer in power as you steer so learn to adjust the throttle for risk losing height

Speed
The tandem can rise faster and also move much faster forward (I quickly learnt this after ignoring the trim adjusting at first and finding that it cleared the room in two seconds, crashing into the wall)

Durability
Both have taken a many knocks, I have hit walls, floors, ceiling etc and there has been no damage to the Picoo-Z or my house. But I have avoided hard stone floors.

Landings
Helicopter - I have made the dinning table in a adjoining room, but its rare
Tandem - Greater success with smaller targets (coffee table), hover and patents are the key.
