Thanks for the input guys!

I think I've decided to keep both engines and the Goldberg cub. I may try the .91 at first, with the idea that the extra power may help get me out of trouble more easily. Depending on how that works out, I'll put the .61 on later and see if that gives more "scale" flight characteristics. The fact is, it will be a while before it's really an issue. I've got to get the Hobbistar 60 in the air first!

Thanks,
