No… not imo.
2 5.5w motors are more inefficient than 1 11w motor. Don’t use them on drivetrains… I’ve tried (both as a 55w and 77w drive).
Stick as many 11w motors on your robot if possible. The rest of your robot won’t matter at all if the other team’s 66w drive can just push you across the field and bully you away from scoring.
Especially since your robot is heavy, you’ll be a slug around the field. You can’t score because 1) you’re too slow to accelerate towards balls, 2) you’re too slow to accelerate to goals, 3) you won’t be able to push opponents away from your goals, and 4) the opponents will just see you and play ping-pong with your robot. Remember, with a 22w drive, they have THREE TIMES as much torque.
