What XL are you guys talking about there is more than one and why is a XL going to be better than a Feigao 540 10L? I'm only guessing that the 10L is the best Feigao? I don't know what numbers to look at to see what motor has the most speed or power?

Can you explain how you know?

The Warrior 9920 will work with almost any motor?

btw do you guys think that the Maximizers would hold up?
