Feilun FT012 - 45 km / h of pure pleasure on the b / c motors

Greetings dear readers! The article, I hope, will be of interest to anyone who is interested in r / c models. Today on the review is a radio-controlled boat with a brushless motor Feilun FT012. I will say right away that the model is quite suitable for its price and in this review I will tell why I came to this conclusion.


She reached me in the standard 25 days in a quite presentable form:

Brief specifications:

• Length: 46 cm
• Width: 12.5 cm
• Height: 11.8 cm
• Battery: 3s 25s 2200 mAh
• Charging time: 2.5 hours
• Work time: 8-9 minutes (enough)
• Regulator: 35A
• Motor: 2815 3500 r / v
• Servo: 9g
• The transmitter requires 6 AA batteries, which is not good. But, perhaps, this is the only minus of the subject of review.
• Radio control frequency: 2.4 GHz.
• Range: 150 meters.
• Maximum speed: 45 km / h (without ripple). With a wind of 5-6 m / s, I managed to accelerate the FT012 to 38 km / h. Measured with SKYRC GPS ( * ref )

The autopsy showed excellent moisture protection of the servo drive and the controller with the receiver (they are in the same package).

The motor, as mentioned above, is brushless. For those who do not know, I will explain. In brushless motors, the specific power (by weight) exceeds the same indicator of conventional hobby electric motors by a factor of two or three. That is, with the same mass-dimensional indicators, the recoil of a b / c motor is several times higher. For example, the maximum speed of a similar boat FT 009 with a collector motor is 22 km / h (I had such a boat). The same indicator of the subject of the review is twice as high. Knowing that water resistance grows in proportion to the square of the speed, you can easily calculate that FT012 is more powerful than FT009 more than 3 times.



A little bit about picking
For this money we get the boat itself:



Plastic stand:



Battery:



Charger:



In my opinion, rather weak, 1A - a little:



Standard transmitter for this manufacturer:





It feeds on six "finger" (AA) elements:



It has the setting of gas trimmers and rudder (rudder), and it is not bad.



Also, there is an adjustment of expenses (deviation angles) of the rudder. I drive at maximum costs. But for those who take the transmitter for the first time, I advise you to set the cost by 50% and not immediately give the maximum gas. Roll out a pair of accumulators in a low-lying position, get comfortable with the controls and train yourself to swap turns left and right when the boat goes towards you. This will save you from unplanned visits to the beach at full speed, or, God forbid, from falling into the bathing. Choose a place far away from the beaches, since the FT012 is not quite a toy. At full throttle, it is quite capable of causing very serious injury to a person in the water.

Well, let's launch this cutter?



As you can see at the end of the roller, the casing is not completely sealed. But for 7-8 minute races it is irrelevant. Water is collected in the cockpit only at the time of overkill (coup), which is extremely difficult to achieve. In the video, I never managed to turn it on the go. For this you need a wave from a passing ship. But the function "autoflip" (a coup back after overkill, controlled from the transmitter) works fine, which can be observed twice in my video.

The function is extremely necessary. It is one thing to drive in the heat of summer, when you can always swim for an overturned model. And quite another - autumn-spring, when the water is completely uncomfortable. Just back up for 1 second and immediately - full speed ahead. The boat turns over to the standard position and continues to amuse us.


I will focus readers attention on one important point:
Included with the boat comes with a tube of lubricant, and this is not just an extra accessory. After a pair of rolled-out batteries, remove the propeller drive flexible shaft and lubricate the deadwood tube with this lubricant. Otherwise, the flow of water into the cockpit is inevitable. Also, this grease protects the shaft and tube from wear. In general, do not be lazy to maintain the model and it will serve you for a very long time. In the absence of brand lubrication, it is quite possible to use the usual automobile Litol-24 (sold in every car shop).

Finally, I will say this, the Feilun FT012 is one of the best boats I have driven. It is worth a lot, or rather $ 93.94 ( * ref ), but I have never regretted it. Reliable and fast, it will delight you no season. For me, this is the best boat of those that I had before.
