Description
Overview
Adaptor leads converting XT and XT60 connectors to TRX (4.2mm), Mini Tamiya (6.2mm) and HXT 4.0mm plugs. This covers the older battery and charger connectors still found on many RC cars and aircraft.
Specifications
- XT-family end: XT or XT60, male or female
- Other end: TRX (4.2mm), Mini Tamiya (6.2mm) or HXT 4.0mm, male or female
- Variants: XT M/F to TRX, XT60 M/F to TRX, XT M/F to Mini Tamiya, XT60 M/F to Mini Tamiya, XT M/F to HXT 4.0mm, XT60 M/F to HXT 4.0mm
- Contacts: plated
- Wiring: red / black
Purpose
Older RC models and their batteries often still use Tamiya or HXT connectors, while modern packs come with XT60. This adaptor bridges the generations so an old model can run on a new pack, or a new charger can charge an old battery, without re-wiring either side.
Applications
- Running modern XT60 LiPo packs in older RC cars and aircraft
- Charging legacy Tamiya or HXT batteries on a modern charger
- Adapting chargers and ESCs with mismatched connectors
- Bench testing mixed-connector setups
How to Use
- Identify the connector on each side, including the gender, before ordering.
- Note that Mini Tamiya and Tamiya are different sizes — 6.2mm Mini Tamiya is not the same as the larger Tamiya plug.
- Observe polarity; Tamiya-style plugs are not keyed against reversal, so check red/black carefully.
- Keep current within the rating of the weakest connector — Tamiya plugs are the limiting element in most chains.
- Push fully home and check for warmth after the first run.
