Prop savers are okay up to about 100 or 150 watts, your mileage may vary. But on my 200W system a prop saver is just unthinkable. I use a bolt on prop adapter. The motor is bolted on backwards and...

That's still a bit curious because it should have said 20Wh. It's unusual to have the Wh rating provided on a pack label.
