The CNHL STUPV2011 is the replacement all-metal nose landing gear retract unit for the AviNationRC Super Tucano V2 1600mm RC plane. It is the powered retract mechanism that raises and lowers the front landing gear and is designed specifically around the revised V2 landing-gear system.
One of the key changes from the original V1 aircraft is the retract construction itself. The earlier V1 nose retract used a black-bodied design, while the Super Tucano V2 moves to a silver all-metal retract unit for a more robust landing-gear setup.
STUPV2011 is the correct replacement when the retract motor or internal mechanism is damaged but the separate nose gear leg, wheel and related steering components remain serviceable.

STUPV2011
All-Metal Nose Retract Upgrade for the Super Tucano V2
The V2 landing-gear system was redesigned around stronger metal retract hardware. STUPV2011 uses the updated silver all-metal construction rather than the black-bodied retract design used on the original V1 aircraft.
This makes the retract unit one of the most visible mechanical upgrades in the Super Tucano V2 landing-gear system and an important replacement component for pilots maintaining the aircraft long term.
Nose Retract Unit vs Nose Landing Gear
STUPV2011 is the electronic retract mechanism that raises and lowers the front landing gear. It is not the complete nose landing gear leg and wheel assembly.
If the retract mechanism still operates correctly but the wheel, strut or mechanical nose gear assembly is bent or damaged, you may instead need the separate STUPV2024F replacement nose landing gear.

Stronger retract construction and improved landing-gear durability
The V2 uses a revised all-metal retract design that differs from the original black V1 retract system.
For nose landing gear, main landing gear, wings, fuselage sections, propeller components and other replacement parts, browse the Super Tucano V1 & V2 spare parts collection.
Confirm the retract unit is mounted securely and squarely in the fuselage.
Connect the retract wiring correctly before cycling the system.
Check that the nose gear extends and retracts smoothly without binding.
Verify there is adequate clearance around the nose gear and gear door.
Check the nose gear door sequencing after installation.
Inspect the mechanical nose gear leg and steering linkage before taxiing.
Cycle the retract system several times on the bench before flight.
Perform a slow taxi test after completing the repair.

I love my V1 so I ordered the V2 as soon as I could!!!!
I love my V1 so I ordered the V2 as soon as I could when it was available in the USA. I was NOT notified via email that I would need to please or solder new connectors for my "first batch" model. I found out via Facebook :(. However CNHL customer service has been above and beyond making sure they make it right by me. Jasmine was awesome! If the v2 flies 1/2 as good as the v1 this plane will be a winner! The upgraded retracts are my favorite new upgrade, gear door is kinda of. let down ...should be automatically sequenced with gears ... the reverse thrust option is nice as well! I recommend the Airplane for pilots who ENJOY a true locked in airframe.
CNHL AviNationRC Super Tucano V2 1600mm PNP RC Plane with All-Metal Retracts
Title: Impressive Voltage Sag Performance Under Heavy Loads
I tested two CNHL Lightning 6S 6000mAh LiHV batteries against four ManiaX 6S 5800mAh HV packs in my SAB ilGoblin 590, equipped with a Scorpion motor, Tribunus III ESC, and VBar telemetry logging.
Both battery types were purchased new for this helicopter and had undergone several charge/discharge cycles before testing. Their manufacturing dates were unknown, so previous storage-related aging could not be determined.
Internal Resistance
* CNHL: approximately 3.5mΩ/cell
* ManiaX: approximately 1.9–2.1mΩ/cell
Based on these readings, I initially expected ManiaX to perform better under heavy loads. However, the actual flight logs showed some surprising results.
All voltage/current pairs are simultaneous measurements from the VBar logs.
Interestingly, the CNHL packs maintained 19.9V at approximately 150–159A, despite having already discharged around 1,000–1,500mAh.
The ManiaX packs experienced greater voltage sag at similar current levels, even though the selected high-load events occurred relatively early in their discharge cycles.
Low-Load Performance
At moderate loads of approximately 30–50A, ManiaX generally maintained slightly higher voltage, consistent with its lower charger-measured internal resistance.
However, this advantage was less apparent during the highest-current events. State-of-charge differences also affect these comparisons.
Important Test Conditions
The CNHL tests were conducted at approximately 18°C, while the ManiaX tests were performed at approximately 10°C.
These were estimated ambient temperatures, not measured battery temperatures. Lower temperatures can significantly increase voltage sag, so the results cannot establish that CNHL is inherently superior under identical conditions.
The tests were conducted on different dates with different flight profiles.
Weight and Usable Capacity
* CNHL: approximately 710g / 6000mAh
* ManiaX: approximately 820g / 5800mAh
The CNHL is about 110g lighter per pack.
Using my normal discharge limits, both batteries provide nearly identical practical usable capacity of approximately 3,950mAh, targeting around 3.80V per cell after resting.
Final Verdict
Despite its higher measured internal resistance, the CNHL Lightning delivered excellent high-current performance in my actual flight tests.
While ManiaX generally showed slightly better voltage retention under moderate loads, CNHL remained highly competitive during aggressive collective pitch maneuvers.
The temperature difference prevents a definitive conclusion about which battery has intrinsically lower voltage sag. Nevertheless, CNHL’s combination of strong high-load performance, significantly lower weight, and excellent value makes it a very impressive battery.
I’m extremely satisfied with the CNHL Lightning 6000mAh and would definitely buy it again.

Surprisingly Good High-Load Performance for the Price
I’ve been testing the CNHL Lightning 6S 6000mAh LiHV batteries against ManiaX 6S 5800mAh HV packs in my SAB ilGoblin 590, using a Scorpion motor and a Scorpion Tribunus ESC with VBar telemetry logging.
My main focus was voltage sag under heavy collective pitch loads, with peak currents reaching approximately 150–160A.
Interestingly, the CNHL packs measured around 3.5mΩ per cell on my charger, compared to approximately 2mΩ for the ManiaX packs. Based on these readings, I initially expected the ManiaX batteries to maintain voltage better.
However, in some of my high-load flight logs, the CNHL maintained approximately 19.9V at around 150A, while the ManiaX dropped to approximately 19.4–19.8V under similar current loads.
One important limitation is that the tests were performed under different conditions. The ManiaX tests were conducted at approximately 10°C, while the CNHL tests were around 18°C. Battery temperature can significantly influence voltage sag, so this was not a perfectly controlled comparison.
Results also varied between flights, but overall I found the CNHL’s high-load performance very competitive with the more expensive ManiaX packs.
Another significant advantage is weight. My CNHL packs weigh approximately 710g, compared to 820g for the ManiaX — a saving of around 110g per pack.
Despite the slightly different rated capacities, both batteries also provided very similar usable capacity in my setup.
Overall, I’m impressed with the CNHL Lightning 6000mAh. It offers competitive high-current performance, noticeably lower weight, and excellent value for money. I would definitely consider buying more.
