I remember going to the GP in Southport years ago. It was a great event. Some of the Losi team came over for it (BK Pops Jnr. etc.)
If they are going to run a GP it would be a worth while event to go to.
For something a little closer.....
There will also be off-road racing in Dublin during the summer. With the new motor way(s), it's only a 2 hr or so drive.
We're in the process of getting a new track ready for the summer.
Have a look at the club site for more details.
