What kind of banana head does a model airplane use? Hot topics and purchasing guides across the Internet
Recently, the discussion surrounding the "banana head" has become increasingly popular in the community of aircraft model enthusiasts, especially the selection of battery and motor connection solutions. This article combines the hot content on the Internet in the past 10 days to sort out the core data and purchasing suggestions for model airplane banana heads to help players make quick decisions.
1. Comparison of popular banana head types
| Type | Diameter(mm) | Maximum current(A) | Applicable scenarios | heat index |
|---|---|---|---|---|
| 2mm banana head | 2.0 | 15-20 | Micro drone/indoor model aircraft | ★★★ |
| 3.5mm banana head | 3.5 | 30-40 | FPV flying machine/small and medium fixed wing | ★★★★★ |
| 4mm banana head | 4.0 | 60-80 | Large multi-rotor/gasoline powered | ★★★★ |
| XT60 compatible head | special | 60+ | High voltage battery pack modification | ★★★ |
2. Current focus of controversy
1.3.5mm vs 4mm debate: The actual measurement by the "veteran aircraft model driver" of UP station B shows that the temperature rise of the 3.5mm head is 12°C higher than that of the 4mm head when the current is sustained at 40A, but the weight is reduced by 30%, triggering heated discussions among traversing machine players.
2.Coating material selection: A popular Douyin video compared gold/silver/nickel plating and found that the silver plating has the lowest contact resistance (0.2mΩ), but the wear resistance of nickel plating is increased by 3 times, making it a new favorite among racing players.
3. Mainstream brand ratings in 2023
| brand | price range | Plug and unplug life | Spark-proof design | User recommendation rate |
|---|---|---|---|---|
| AMASS | ¥15-30/pair | 500+ times | Yes | 92% |
| XTAR | ¥8-20/pair | 300 times | None | 85% |
| Gens ace | ¥25-50/pair | 800+ times | Yes | 88% |
4. Purchase decision tree
1.Current demand takes priority: Select specifications based on motor peak current. It is recommended to reserve 20% margin.
2.Space limitation considerations: A 2mm head is optional for the mini model, but it needs to be combined with a silicone wire to reduce weight.
3.Maintenance cost calculation: For high-frequency disassembly scenarios, it is recommended to choose the gold-plated version. Although the unit price is high, the lifespan is longer.
5. Expert advice
"Blue Sky Craftsman", the technical moderator of the model aircraft forum, proposed:"The new trend in 2023 is a mixed use solution - 4mm is used on the motor end to ensure power supply, and XT60 is used on the battery end to prevent misinsertion.". This solution received 12,000 likes on Tieba and was actually tested to reduce the failure rate of the connection system by 40%.
