I agree about the search feature. We have discussed this airplane a lot. There a lot of threads here in the fun fly forum about why motor, what servos.

As I said before and I will say it again. use a YS 63. Way to much motor, But isn't nice to have the that much power.

A YS 91 would be way to heavy, and way to much power. If you use a YS 91 on it get ready to buy you another top cap because you will pull the plane apart.
