From last years list, AndyL has 4, JimP has 2 and if the one in Cadders' car is mine, I also have 2. But with so many cars going we going to need some more as a group. Could noobs with any speak up. otherwise, Ebay is the place. Look for any without docking stations as the batteries can be easily removed and recharged with a standard AAA NiMH charger. Which I will have with me. Avoid binetone ones! But make sure you get 446MHz ones. TG
