High-performance 55A ESC, compatible with 10-13V, for radio-controlled models. Used in helicopters such as Protos and TREX. Instruction manual is not included, but I have attached images of the manual, so please refer to them. The power cord has been extended, and the plug is still attached; consider it a bonus. Can be switched to glider or airplane mode. Jumper pins are not included. - Model Name: Jazz 55-10-32 - Current: 55A - Voltage Range: 10-13V - Model Name: Jazz 55-10-12 Thank you for viewing.
