RE: 4 Ch electric foam Cessna (for beginners)
A good foam cessna is a different story. I have an E-Flite cessna 182 with hitec servos, 25A ESC and brushless 370 motor. The functional struts help with the wing but I didn't trust the wing bolt and added a fender washer to keep the bolt from ripping through.
Even though the E-Flite is better I still would not recommend it for a beginner.
