RE: E-flite tensor 4d
I liked mine OK at 10 ounces, two seasons ago. When they hit $25, I bought another. With light equipment, my new one hit 8 and 1/8 ounces. Now that's a slow flying plane...
I also left off all the little rods and such from the core, and just did the lower wing like it was a shockflyer. I even dumped out of a roller, right on the wing tip. No damage.
