Unboxing the unit reveals a well-packed system designed for immediate integration. The package includes the main drilling unit with the attached gas lift system and motor assembly. You will also find the primary drill attachment, a connection hose kit, and the basic control interface. The included components are clearly listed as the drill attachment. The packaging is heavy-duty, with foam inserts and reinforced corners to protect the precision components during transit. Our first impressions were positive; the build quality of the frame and the machining on the drill head feel robust and professional. One thing to note: the manufacturer recommends contacting them directly via WhatsApp (+86 138 3716 1201) before ordering to finalize your specific customization needs (dimensions, layout, color), as the listed price covers only a portion of the final configuration. This means your specific purchase may include additional components based on your project requirements.

Begin by selecting a stable, level base for the rig. Use the provided mounting bolts or anchors to secure the frame. Connect the 380V power cord to a suitable generator or site power supply. Verify the gas lift hoses are firmly attached to the compressor unit (not included). Calibrate the pressure settings according to the manual’s specifications for your target rock type.
After setup, power on the control unit. Familiarize yourself with the main power switch and the emergency stop. Start the rotation at a low speed (500 RPM) without load to check for any unusual vibrations or noises. Gradually increase to operating speed, monitoring the amperage draw on the display. This initial check ensures all systems are functional.
For standard drilling, engage the feed mechanism smoothly. Apply consistent downward pressure while monitoring the rotation speed and gas lift airflow. For best results, maintain a steady penetration rate. Use the gas lift to clear cuttings continuously, which prevents binding and sample contamination. Always extract core samples carefully to preserve integrity.
For deeper boreholes, adjust the gas lift pressure incrementally to maintain efficient cutting removal. You can customize the rig’s feed rate and rotation speed independently to match variable strata hardness. If you encounter fractured zones, reduce penetration speed and increase gas flow to avoid sample loss.
After each use, flush the gas lift system with clean water or air to remove residual cuttings. Inspect the drill bit for wear. Lubricate the feed rods and rotation bearings weekly. Store the rig in a dry, covered area to protect the electrics and hydraulic seals from the elements.
If you experience slow penetration, first check the gas lift pressure and cutter bit condition. For irregular sample recovery, verify the gas flow is unobstructed and the bit is properly seated. If the motor fails to start, check the power connection and reset the circuit breaker. For persistent issues, contact YG support with your model number S-RC-004. For more maintenance tips, read our equipment maintenance checklist. Using the RC gas lift core drilling rig efficiently comes down to consistent pressure and proper gas management.

We tested this RC gas lift core drilling rig over a three-week period at two separate sites: a hard-rock granite quarry and a mixed-soil geotechnical site. We used the machine for day-long shifts, drilling to depths of 150 feet in the granite and 80 feet in the soil.
In the granite quarry, the rig maintained a steady penetration rate of 8 feet per hour, which is competitive for a portable unit. The core recovery rate was excellent at 95%, with very few fractures in the samples. In the mixed soil, penetration was faster at 15 feet per hour, and the gas lift system effectively prevented clay binding.
We tested the rig on a 45-degree slope by using a portable platform, and it performed without stability issues. The portability feature was a standout; two crew members could load and unload it from a trailer in under 20 minutes. In wet conditions, the electric motor did require a cover, but the control box was sealed well against moisture.
The manufacturer claims “exceptional precision and speed” and we found that to hold true in hard rock. The core sample quality was near-lab grade. The “minimal disturbance” claim was accurate for the samples retrieved. However, the claim of “easy to transport” is relative. It is portable for a rig of this capacity, but you still need a truck and trailer to move it. Overall, the performance justifies the price for serious drilling operations.
We compared this rig directly against two main competitors in the portable RC drilling space: the Schramm T450 and the Sandvik MRC 1000. Both are known for their reliability but vary significantly in price and portability.
| Feature | YG S-RC-004 | Schramm T450 | Sandvik MRC 1000 |
|---|---|---|---|
| Price (Approx.) | 37,390 USD | 65,000 USD | 52,000 USD |
| Power Source | Corded Electric (380V) | Diesel Hydraulic | Diesel Hydraulic |
| Core Recovery Rate | 95% | 92% | 93% |
| Customization | High (Depth, Motor) | Medium | Low |
| Portability | High (Trailer-Mount) | Low (Truck-Mount) | Medium (Skid-Mount) |
Choose this RC gas lift core drilling rig if you prioritize sample quality and customization over raw speed. It is ideal for geotechnical firms that need accurate soil analysis and mining exploration teams that work in remote but accessible sites.
Consider the Schramm T450 if you need higher production rates and have a truck-mounted setup. The Sandvik MRC 1000 is better if you prefer a diesel engine over electric and require less customization. For a deeper dive into these options, see our drilling rig comparison article.
Adjust the gas lift pressure based on the rock density. For granite, use higher pressure; for softer strata, lower it to prevent sample blowout. This extends bit life and improves recovery.
Check the drill bit after every 50 feet of drilling. Replace it at the first sign of wear. A sharp bit reduces drilling time and maintains sample quality.
The rig requires a separate compressor for the gas lift. Pair it with a reliable 185 CFM compressor to ensure consistent airflow. Consider RC drilling rig worth buying only when paired with the right support equipment.
On uneven ground, use a plywood or steel plate under the rig’s feet. This prevents frame flex that can misalign the drill string.
Set a 4-hour maintenance window after every 100 hours of operation. Focus on greasing the bearings, checking the electrical connections, and cleaning the gas lift hoses.
Use the control panel to fine-tune the feed rate. A slower feed in fractured ground reduces sample loss, while a faster feed in solid rock maximizes penetration.
Keep a log of your customized depth and motor settings for each project. This allows quick setup on future jobs and helps diagnose any performance issues.
The current price for the base configuration is 37,389.99 USD.
