Yea, you're probably right. I forgot about Carrolton.
JT's is on Camp Bowie. If you go down I35 W to Ft Worth, you will take 820 west around the western side of Ft. Worth. Just south (less than .5 mile) of the 820/I30 interchange is Camp Bowie BLVD. Take Camp Bowie about 1.5 miles East and JT's is on the North Side of the road. He has a website with some stuff, but not really an online store. You can google JTs hobbies in Fort Worth.
While you are down there, you might as well take a plane and drive on down to fly with the Thunderbirds for a day. They are in Benbrook, just a few miles south of JT's. Very nice place to fly and good people. Lot's of turbines and other high dollar planes out there. JT (owner) flies turbines and is in fact a top gun first place winner from a couple of years back.
you can also google the fort worth thunderbird RC club and find out more information on that.
Would be well worth your trip, and they always welcome AMA guests....
