Hitec,
I just flew my Lazy Tiger today with a 40LA engine. Flies great and will do great vertical. Plus, I didn't need to put any additional weight anywhere and it still glides in for landings. I've got an 11X5 Master Airscrew prop on it but don't have an RPM yet. I really like this plane. Had several guys at the field asking about it. If you're good with throttle control, the 46 LA is the same case as the 40 but like someone already said, watch your prop size. I put a little larger wheel on it and as long as the field isn't bumpy or you have a paved runway, you'll be fine. I walk mine to the runway and place it on the smoothest section I can find since we've got grass. I've got an Evolution trainer three-bladed prop I'd like to try once I get a little more fuel through it. Hoping it will look just a little more realistic than the dual prop and it's about a 1/4 inch shorter on the blades.
Hope you like your Lazy Tiger as much as l like mine.
Andy
