The HOR's are great planes! I don'dt know what the GNAT is.

One thing to worry about when flying the HOR is what your opponents are flying. If y'all are flying HOR's, no problem. But, if you are competing against some more advanced designs- you'll find that you will be outclassed in terms of flying speed, performance, and imortantly- durability. I've seen a lot of foam wing based models tear up HOR's, and not even flinch. As far as speed and performance, I think the foam wings give better aerodynamic performance. I remember my HOR's tended to bleed a lot of airspeed when turning hard.

have fun- Minnesota flying. I bet you really have to open the needle valves for those sub-zero days??
