The first impressions

When I have seen for the first time the small electrical helicopter of corporation Kyosho in the catalogue, I have perceived, what exactly this helicopter will be at me first. That Kyosho it is always skilful to do on 5 points so it is advertising and package! The assembled helicopter - a dublicate of present Schweizer 300C - in a transparent box looks zavorazhivajushche. However, and out of a box the first impression about model too remains positivegoing. If it to express in a word will be closest - "quality". The good plastic material, excellent study of details of a fuselage – all it does not go to any comparison with other small helicopters. As has displayed experience, plastic material not only is well looked, but also not broken at shocks.

In general, the first impression the helicopter to construct knows how. And here further not all so is smooth … However, about it later.

Complete set

As it was already spoken above, the helicopter is packaged into a box, at which one forefront (where there is an assembled helicopter) – transparent. Under helicopter the secondary generator with a charger, sideways – the control board lies. Why the generator has not made at a box from above the pen, probably for ever remains a puzzle. Almost all small helicopters sell in boxes-small suitcases which one so was friend to tolerate. And after all the box from Caliber M24 longer, therefore the pen is simplly indispensable! Well is not present, so there is no, however a deposit, as they say, remained.

So, all enters in a complete set indispensable for flying except batteries for the board. Namely:

  • Assembled model of the helicopter with fuselage Schweizer 300C
  • All electronics (is already established)
  • The control board
  • The secondary generator and charger
  • The training chassis
  • The operating instruction
  • Stickers
  • Stock gearwheel of the main motor and the lock ring of an axis of a caudal curl
  • Clue-shestigrannik

To buy in addition it is necessary only 8 batteries or secondary generators of type AA in the control board.

As it was my first helicopter, presence of the training chassis has very much pleased and the extremely necessary thing for the green hand! And the stock gearwheel has as an unit appeared simplly indispensable. The matter is that is almost unique detail which one fails it has appeared rather beneficial. With it at me began to manage to lift off, thus not having filled up sideways. At emergencies of mean gravity (shocks by arms and fall from a small altitude). This stock pinion was useful in the first day of flyings.

On the secondary generator the size is not indicated. The charger is supplied by muffled placards about 7.2Vи NiCd though should load 9.6VNiMH, however loads like normal. The secondary generator suffices minutes on 5 flyings, it is no more. And the charger slow – loads 12-15 hours. It is received – 5 minutes we twist a propeller, then we are see you tomorrow loaded. However, not such large flight time is related to structural features of the helicopter (rather big weight of a "duplicator" fuselage).

But problems with the secondary generator can be decided, using a good charger. A large current the secondary generator can be loaded approximately in an hour and "vkachat" in it hardly less than 700 mAh. Then flight time is incremented about comprehensible 8-10 minutes. The charger going as a unit is visible, manages the functions not the most optimum fashion. So it is better to use a good battery charger.


Model technical datas:

  • Length: 430 mm
  • Breadth: 88 mm
  • Altitude: 154 mm
  • Diameter of the main curl: 500 mm
  • Diameter of a caudal curl: 140 mm
  • Weight: 380 g
  • The drive: SPower 24 (28T)
  • The control board: 35MHzMode 2 (the gas pen at the left)
  • The secondary generator: 9.6V NiMH

From the reference specifications at once it is visible, that the model is heavy-dutier than analogues approximately for 100 Thus diameter of a curl hardly less. To raise the helicopter and was the secondary generator 9.6V as it is necessary for rise of heavy-dutier model of more engine speed and, hence, bigger pressure is taken.

I do not claim for a professional knowledge of a mechanics of helicopters, therefore I will feature its words of "teapot". Control of a curl end implements by means of two servos and system of thrusts. All details – plastic, that cannot ensure a control split-hair accuracy, but they are not broken and not bent at emergencies. The caudal curl is operated by the engine established on a tailing. It is necessary to mark excellent quality of plastic material of arms of curls – it very flexible and holds all shocks. On other models of the arm fly apart at shocks, how much I remember.

As to electronics then there is a minus – all is collected in the unified setup unit. It is termed M24-HControlUnit and aligns in itself speed governors of the main and caudal motors, the gyro and servos. Yes-yes, servos too a part of this unit. Such layout is bad at least for two parents: if something is broken, it is necessary to throw out the whole unit and to buy new, and it is visible, nedeshev, and second – there are no regulations. On models where separately, it is possible to set up the gyro and regulators both the gyro and relation of cycles of the main and caudal curls (it is necessary, if, for example all time will withdraw a tailing aside). And here you will set up nothing, though it would be necessary, because just the caudal curl "rows" rather badly – in one party the tailing is turned well, and in another – hardly. Certainly, the helicopter all the same flies and to study on him it is possible, and to take pleasure too. Simply, when you will a little have, you perceive, that to it does not get an adjustability, and that it not so is robust as some other models (it I about the multiple-purpose electronics unit). So, we will look, whether this beautiful piece in air can keep, and, what the most important thing, whether it is possible to learn on it to fly, whether it is suit as the first model of the helicopter?

Take-offs and falls

Yes, on this model it is possible to study to fly. Also it is visible with smaller financial losses, than on other models of minihelicopters. But about all one after another.

The first tryings to take off there were dwellings. As the green hand I believed, that the place will suffice, and I will manage. At first I simply twisted a propeller, being afraid to mount. Then has a little grown bolder, and the helicopter began to creep here and there, still touching a floor. At the first trying to rise still above, it has resolutely departed to me, and I any more did not know, that with it to do. All was ended by not strong shock on legs, as a matter of fact arms were tangled in trouser-legs … But gas has not been dumped beforehand, and the gearwheel on a motor was transformed into the cylinder. All t cut off absolutely. But it is necessary to give back a pinion due (it was confirmed and afterwards), she incurs all load, is broken, but remaining parts – arms, thrusts, a swashplate – remain whole. Here I also have perceived, the stock gearwheel and why it enters at once in a complete set what for is necessary! Japanese foreknew all!

Further, after several tryings to take off in a room, I nevertheless have decided to go to a timber on a grassy clearing in calm day. There grass-snake of room will suffice. I have attached the training chassis, have delivered the helicopter on the trampled down sand (by the way, very easly and at the same time soft cover) and began to work as gas more resolutely. And here it was received! I could take off! It is low-level, the truth, but has taken off. And even it began to be received to retain the helicopter. It, of course, took down aside, but it could be captured and in a critical situation to plant. The training chassis here has very much helped – with it complicatedly to fall sideways, even from an altitude on it drop, as on a cushion.

Was relevant still to mark languid behaviour of a tailing, it is turned slowly, is quiet – first it can be even plus. If it is fair, I could work only as gas and adjust helicopter flying to the left-to the right and forward-back. Here the languid tailing also has helped, since especially did not move anywhere. If it was necessary to capture it at me brains simplly would begin to boil! Generally, all small helicopters it is such piece which one as soon as will take off, strives to get away in any party. And the problem of the pilot to catch it, and then to point more narrow where it is necessary. First it is necessary to be concentrated on tutoring to a hanging before itself. It will allow to perceive how to act control handles and as the helicopter reacts to them.

As to the agenda of emergencies basically it is crashes with furniture and walls of the dwelling, fall, zavalivanija sideways in the street. At home all is simple. If before shock has had time to throttle back (and it it is necessary to do first of all not to hurt model and) consider, it was dressed free of charge. Arms very soft, are not broken even at the strong shocks. Has not had time to throttle back – most likely, it is necessary to go to store behind the alternate gearwheel. In the street for emergencies it is more than capabilities. Aftereffects depend on an altitude. But besides with the cleaned gas of a tangency arms even cutback asphalt are finished only by scores.

As a result, Caliber M24 it has appeared quiet enough and soft. Its large weight and slowness help the green hand more likely, than prevent. But adrenaline all the same reads off scale! Feel from flying simplly surprising – here both pavor, and surprise, and confusion … Words you will not transmit.


So as a result? On the one hand flaws as regards the secondary generator and impracticality of electronics. With another – high quality of the details, shocking persistences to shocks and druzheljubnost to green hands. Most easier to figure all pro's and con's on bowls of a scales.


  • Small flight time and large time of charging of the secondary generator at utilisation of a regular battery charger
  • All electronics is integrated in one unit
  • Impossibility of tuning and betterment


  • Beautiful package
  • The helicopter – very beautiful dublicate Schweizer 300C
  • High quality of plastic material
  • Completeness of a complete set + the training chassis and spare parts
  • Durability to shocks
  • Selfrelative easy of steering for green hands

The solution as always receives everyone for itself.

Helicopter Caliber M24 model the store of Hobby has given for the review a Center.
