Rc Helicopter Reviews Hkh 450

The HKH 450 is a clone almost 100% based on the Trex 450 model radio controlled helicopter. This 450 size helicopter is ridiculously cheap to buy, but does have some problems. The quality of the parts are a bit suspect, but at a quarter of the price of a real Trex, it’s difficult to justify any complaints about the standard of manufacture.

Once you’ve parted with your 25 plus pounds sterling for your helicopter, and waited for the delivery from Hong Kong, what will you receive? Well, the little shoebox size parcel, which falls onto your doormat, is worth the wait, but it doesn’t contain a ready to fly helicopter.

What you will receive is a fully built helicopter head and tail, partially built frame, skids, blades, tail boom, and tail blades. To fly, you will need to purchase four servos, a good head hold gyro, li-po battery and charger, an electric brushless motor, an esc (speed board) and a six-channel radio transmitter and receiver. You must check that your transmitter has a CCPM swash function before you buy it.

There are no instructions what so ever included in the kit, so you will need to download a Trex SA manual from the Internet. A Trex SE manual will also do the job, but the SE head is metal, whereas the SA head, like the HKH, is plastic. Any one of these manuals will aid you with advice in building and setting up the HKH 450.

It is advisable that you completely strip down the pre-built head on your new HKH. This may seem a lot of work, when all you want to do is put everything together and make that first flight. You must remember that this clone had build problems, so take the time to check over the quality of the build of the head and frame.

Use a screw lock such as Locktite or Bondloc, to secure the screws into the metal parts. Don’t use screw lock on plastic parts, as the bonding agent will soon damage the plastic. Once you have checked over all these parts, you can put your helicopter together, using the Trex 450 manual to guide you.

As stated earlier, there are a few weak areas on this helicopter due to poor quality parts. These parts should be replaced either during the initial build, or soon after. The links on the head should move freely, but are known to stick. If the links on your model stick, and you don’t replace them, you will never be able to fly the helicopter successfully.

The tail gear assembly lower gear is renown for spinning on its shaft, so like the links, replace this as soon as possible with Trex Align parts. The screws holding the model together are also a weak area, rounding at a drop of a hat. Again, any parts can be easily replaced with Trex Align original components.

The HKH 450 has a number of faults, with sloppy head components, iffy tail gear, soft plastic components whose threads round easily, but it is cheap. This is acceptable when you are learning to fly radio-controlled helicopters, as it is inevitable that you will crash.

Whether it is learning to hover, or trying out a more complicated new manoeuvre, you will definitely damage the helicopter. The low cost of the HKH 450 initial purchase and parts, allows you to stop worrying about the cost of a crash, and get on with the fun of flying.

As for flying this helicopter, it performs well enough to cope with 3D flying, or simply hovering about your garden. It is a cheap way to get into 450-size helicopter flying without breaking the bank, but just be aware that the quality of the parts does reflect the low cost. Take your time with the setup, and you will have a helicopter, which will perform almost as well as a model may times the cost.
