Kenneth, I am in Nashville TN. One of the guys I fly speed limit with used to fly 1/2a in AZ I believe. He sold his 1/2a stuff before moving here. We got to talking and decided to get a couple of Fora's to mess around with. Then last week I found out the Profi's were in and we got two of those. I guess the airplanes are not really Litehawks per say, just similar. My buddy got us some cores from Steve Stewart (spelling?) that we are going to try. I cant tell you exactly what they are but they are longer than Hacker cores. Anyway we are really just tryin stuff out right now and gathering info from people who can help. Thanks for the reply, any other suggestions would be welcome. Mike P.S. I have flown CL for a long time but just got into Speed Limit last spring, so building combat stuff is pretty new to me.
