The CNHL STUPV2012 is a replacement all-metal main landing gear retract unit for the AviNationRC Super Tucano V2 1600mm RC plane. This powered retract mechanism raises and lowers one of the aircraft's main rear landing gear assemblies and is designed specifically for the revised V2 landing-gear system.
The Super Tucano V2 upgrades the retract system with a silver all-metal construction, providing a more substantial mechanical foundation for the main landing gear. STUPV2012 is the appropriate replacement when the retract mechanism itself is damaged or no longer operating correctly while the separate main gear leg and wheel remain serviceable.
Please note: this SKU is the electronic retract mechanism only. The main landing gear leg, sprung oleo strut and wheel are separate replacement components.

All-Metal Main Gear Retract for the Super Tucano V2
The V2 landing-gear system uses revised metal retract hardware for both the nose gear and the main landing gear. STUPV2012 is the dedicated retract mechanism for the main rear gear position and uses the updated silver all-metal construction seen across the V2 retract system.
This stronger metal-based design is one of the key mechanical changes introduced on the Super Tucano V2 and supports the sprung main landing gear used for takeoff, landing and ground handling.
Main Retract Unit vs Main Landing Gear
STUPV2012 is the electronic retract mechanism mounted inside the aircraft. It is responsible for extending and retracting the main landing gear but does not include the external gear leg, sprung oleo strut or wheel.
If the retract mechanism is still working correctly but the wheel, strut or main gear leg is bent or damaged, you may instead need the separate STUPV2025W replacement main (rear) landing gear.
The Super Tucano V2 uses a revised all-metal retract system. This STUPV2012 main landing gear retract is a V2-specific replacement and should not be treated as interchangeable with the original V1 / Avios Super Tucano retract system.
For main landing gear legs, nose gear components, fuselage sections, wings, propeller parts and other replacement items, browse the Super Tucano V1 & V2 spare parts collection.
Confirm the retract unit is seated squarely and securely in its mounting position.
Connect the retract wiring and connector correctly before testing.
Check that the main landing gear extends and retracts smoothly.
Verify that the retract mechanism does not bind through the full operating range.
Inspect the separate main landing gear leg, wheel and sprung strut before installation.
Cycle the retract several times on the bench before flying.
Check both main gear sides for consistent extension and retraction.
Perform a complete landing-gear inspection after the first landing following replacement.

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.
