Here is the BLS 351, just came in today. Same super tight geartrain of the BLS 451, but with 217 in-oz @ 0.13s on 6V its stronger and almost as fast. Should make a superb replacement for the 9351, or 9155 on rudder applications.

Again all metal geartrain with the exception of the 1st gear which is nylon with a metallic pinion.

Unfortunately its -20c here and there is a fair bit of snow....so it will be a while before there is a flight report
