I don't know about the Projecti, but the F-27C Stryker RTF is an advanced park flyer. I doubt you would be able to keep it in the air for more than a few seconds.

Buy a simple trainer kit, spend 40 - 60 hours building it, when ever it flys your heart will leap, you dont need speed to give you a thrill.

I still glow with pride every time a plane I built takes off, and I am always nervous when I take them down to land.
