Virtually NIB Hacker A50-16s motor

CHECK THIS OUT! This is the motor that is recommended for popular 50/60 size pattern and 3D planes up to 7 lbs; however it will work great in sport planes up to 10 lbs. I installed this motor into a 70" 3DHS AJ Slick and flew exactly three flights. It just didn't have the vertical power I wanted for this plane. I use the same motor in my 62", 7 lb. pattern plane and it has more than enough power for unlimited verticals.

Asking $100 shipped to you CONUS. Thanks for looking!

Here are the specifics for the motor:

The Hacker A50 Series motors are designed for the very popular .60 size models. Intended as a direct replacement to power your model with quiet and clean electric power. The powerful and efficient 14-pole "Outrunner" Brushless motor design creates massive torque, which will allow you to direct drive larger props without needing a gearbox. This motor features Oversized bearings, curved Neo-magnets, and uses High-efficiency stator design. Additionally you will find a special large concentric bearing located in the rotor to support the rotating mass during extreme 3D maneuvers. A cooling fan is mounted on the motor to provide proper motor cooling for closed cowling or helicopter applications. Features an integrated 8mm threaded shaft and prop adapter for superior reliability.

Is it 50-16, or 50-12? I thought 50-16S has kV of 360 or so.

Thanks for noticing this. It is an A-50 16S, but you are correct, I had the wrong kV posted. I have corrected the kV to read 378 as shown on Hacker Technical data that comes in the box. Thanks again.

Bob,

Absolutely! Sorry for the delay in answering. I check for PM daily, but don't always check on the listing site that often.
