A bit of background: Years ago in my youth I had a go at RC flying. The main thing I learned was that crashing was expensive and potentially dangerous for whoever was under the plane.
Now in semi-retirement, I looked at cars and boats, got the Flysky FS-I6X and a bunch of extra IA6B receivers (they were same price as 3 ch at the time). Have scratch built a couple of boats and quite happy with the I6X, but never tried a wheel transmitter. Lots of people at the lake using them so got the GT5.
Still got an origional tamiya hornet that I could retrofit with brushless/lipo/gyro and see what happens......
