| The following is a review of the Hyperion eight and six-channel receivers with Berg technology. Provided by www.aircraft-world.com for review. First let's take a look at these compact receivers : |

| Both of these receivers are PPM modulation rather than PCM. However, unusually
for a PPM receiver they contain much of the functionality you may normally
expect to find only on a PCM receiver. As an example these receivers have
failsafe built into them just like a PCM receiver. The Berg technology
uses something called transmitter signature recognition. The way this works
is that when you switch on the receiver it keys itself to your transmitter
and will only listen to that particular transmitter. This process happens
everytime you switch on the receiver and although I can't claim to understand
how it works it is one of those technologies that just 'works'.....you
don't need to understand it. The receiver is programmable to have failsafe mode on or off by placing a jumper on one of the servo outputs and then powering the receiver on. Depending on where you put the jumper the receiver will program to go into failsafe or just use HOLD mode. In failsafe mode you can program where you want your servos to go should a loss of signal occur. In HOLD mode should a loss of signal occur then the servos will just stay where they are and not move to any preset positions. All of the programming is achieved by placing a jumper on one of the servo outputs and then using the transmitter to do any servo positioning for failsafe. Aircraft-world have a datasheet that explains this process in detail and this comes with the receiver. It can also be accessed online here. The first thing anyone should do on installing a new receiver is to conduct a range test with the transmitter aerial down. Normally I do this with one motor wire disconnected so that the model cannot take off. Something that was crucial to this review was to understand whether the 'long-range' claims usually associated with a berg receiver were true. In order to conduct this test I used two T-Rex on the same channel. One T-Rex I fitted with a Hitec Electron receiver. The second T-Rex was fitted with the Hyperion receiver. I then backed away from both models until one of them started to glitch and have control problems. The T-Rex fitted with the Electron receiver was the first one to start having problems. However, I was totally unprepared for just how much more range the Hyperion receiver was capable of providing. When I finally did get out of range of the Hyperion receiver I was almost three times as far away! At this point it is worth stopping and just talking briefly about my experiences flying the T-Rex using an Electron receiver. Firstly I expected to have on average five glitches in any one flight. Secondly I had got used to flying not too far away from myself as the glitches got worse at a distance. My understanding was that the Electron receiver was a reasonable quality receiver and that this type of behaviour was fairly normal for a compact sized receiver. Given that the above was my expectation of any compact receiver I was about to get a long overdue wakeup call. Over the past couple of months I have been flying both of these receivers. In that time I have had in excess of 50 flights. So far I have not experienced a single glitch when using these receivers. In addition I have never managed to fly my T-Rex beyond the range of these receivers. I did on one occasion attempt to see if I could fly out of range. My plan was to fly straight upwards and see at what point I could detect a loss of control. The result was that I gave up as I got so high I actually couldn't see the T-Rex any longer! At this point I closed the throttle back and waited for the spec in the sky to reappear, which it duly did and I guided her back in to a safe landing. You couldn't ask for more than that. Conclusion In general the products reviewed on trextuning do what they say. It is on very rare occasion that I find a product which doesn't perform to specifications (obviously I exclude some of the wild 'C' ratings seen on lithium packs). In this instance I was expecting an above average receiver. What I wasn't expecting was to discover a product that was to totally transform my flying experience with the T-Rex. I cannot recommend this receiver highly enough, not only does it perform faultlessly but it is also of superb quality and has a huge range. Added to this it comes at the same price as most other average quality PPM compact receivers on the market. If you currently have a T-Rex that glitches or that you don't trust flying at range then this receiver will be one of the best investments you ever make. I no longer worry about radio issues when flying my T-Rex and I know for certain that if it crashes it is a mechanical failure or my own dumb thumbs. This confidence is a welcome commodity when trying to learn new 3D moves where a glitch at the wrong moment would be catastrophic. I don't like 'rave reviews' but I'll make an exception in this instance. If you would like to discuss this review in the forum, click here |
