These RC retractable landing gear, can be used in a scratch built RC airplane or as a replacement part in an existing model.
This video shows us much more than just the JP Hobby retracts. The 90mm EDF unit as well as the matching ESC are shown. But there are excellent shots of the retracts as well.
