which one is better the HET f-16 or the HET f-18. i want the HET f-18 more but it is about $50 cheaper than the f-16. i don't know why it is more expensive? The HET f-16 has a fiberglass fuselage and one motor while the HET f-18 has lite-ply and balsa fuselage and one motor. Is fiberglass better to have as a fuselage? if i accidentally crash which would be more durable. When i land on dirt or grass which would be better the fiberglass or the lite-ply and balsa (oracover-ultracote covering)? which is more durable oracover or ultracote. plz help me i need to decide
