The Yikong DF7 “Desert Fighter” (item no. YK4072) is a 1/7-scale, four-wheel-drive, brushless desert truck sold ready-to-run by Chinese manufacturer Yikong. It is 713 mm long with a 425 mm wheelbase, weighs about 6.3 kg and uses a 4274-size 1600KV brushless motor with a 150A speed controller on up to 6S LiPo. Four versions have been sold so far, V1 to V4: the layout has stayed the same, while the body, chassis and steering hardware have been revised along the way.

Overview
The DF7 is Yikong’s large-scale desert truck: a short-course-style polycarbonate body over a roll cage, long-travel suspension with eight aluminium shocks, and a shaft-driven 4WD drivetrain with a CNC aluminium centre differential. It comes assembled with motor, speed controller, steering servo and a five-channel 2.4 GHz radio whose receiver has a built-in gyro. Batteries and a charger are not included.
In the retailer listings we checked, the basic numbers are the same from the V1 to the V3: 713 × 352 × 270 mm, a 425 mm wheelbase and 6.3 kg. What changes is the hardware around them. The V2 brought a new body and lighting; the V3 a three-layer aluminium chassis, aluminium front lower arms and a stronger steering servo; and the V4 is listed with a 4 mm aluminium main chassis, a 40 kg servo and fixed XT60 battery connectors.
Which DF7 version is which?
The truck keeps the same name through every revision, so the quickest way to tell the versions apart is the item number and the colour. The V2 is YK4072V2, in red or blue. The V3 is YK4072A or YK4072B; the A is green. The V4 is sold in metallic violet and metallic orange. The sections below go through each version and then set all four side by side.

DF7 V4 YK4072 V4
We have not seen an official change list for the V4, so the points below are the ones two retailer listings agree on. The same two listings disagree on overall size, battery-bay size and price; both sets of figures are in the comparison table.

- 40 kg metal-gear steering servo
- 150A speed controller rated for 2S–6S LiPo

Yikong DF7 FAQ
What scale is the Yikong DF7 and how big is it?
The DF7 is a 1/7-scale truck. Retailer listings for the V1, V2 and V3 give a length of 713 mm, a width of 352 mm, a height of 270 mm, a 425 mm wheelbase and a weight of 6.3 kg.
What battery does the Yikong DF7 need?
No battery is included. The V2 and V3 listings call for two 3S LiPo packs, or a single 4S or 6S pack with a short-circuit (jumper) plug, and give the battery tray as 181 × 47.5 mm. V4 listings state 2S–6S support with fixed XT60 connectors, while the V2 listing we used pairs the truck with EC5 packs, so check the plug on your truck before buying batteries.
What is the difference between the DF7 V2 and V3?
Size, weight and motor are the same. The V3 listing adds a newly designed three-layer aluminium chassis, CNC aluminium front lower arms and CNC steel spiral bevel gears, and lists a 35 kg steering servo in place of the V2’s 30 kg unit.
What is new on the Yikong DF7 V4?
Retailer listings for the V4 agree on a 4 mm aluminium main chassis, a 40 kg steering servo, a 150A speed controller for 2S–6S, fixed XT60 connectors, two symmetrical battery bays and metallic violet and metallic orange colours. They do not agree on the truck’s overall dimensions, and we have not seen an official change list.
How fast is the Yikong DF7?
None of the listings we used gives a top speed and RCFans has not measured one, so we do not quote a figure. Top speed depends mainly on battery voltage (up to 6S) and gearing.
Is the Yikong DF7 ready to run?
Yes. It is sold assembled with motor, speed controller, steering servo and a five-channel 2.4 GHz transmitter with a gyro in the receiver. You need to add LiPo batteries, a charger and four AA cells for the transmitter.
What does YK4072 mean?
YK4072 is Yikong’s item number for the DF7. Retailers extend it by version and colour: YK4072V2-R and YK4072V2-B for the red and blue V2, and YK4072A and YK4072B for the V3.
