RCKen, I can check with my local club here in my town to see if they can use a radio or two, once to twice a year we have a group of boy scouts come to our field to try their hand at model rocketry and as their treat we set them up on buddy boxes. If you have a transmitters and receivers for two planes and two more I believe four channel transmitters that can be used as the buddy boxes I think that will come in pretty handy.
