How about 2 more radars a 3 pack of 10 minute radars and a 6 pack of 5 minute radars. there are plenty of times im in a group that is forming and the 15 is too long. I'd love to be able to run a 5 minute radar. i would probably run those more since im rarely flying solo for a full 15 minutes.
I don't use any radars at all, but I can see how this would be very usefull for people who do. +1 for this idea.
