I need a micro servo for retracts that would be the same size as the HiTec HS-82mg. Would like to have metal gears. Thanks

I have (2) of these in a Cherokeeish plane for the retracts. One For the main gear and 1 for the nose gear. They are GWS micro retracts. You did not say what size your retracts are.
