Most of them appear to be control line models but I found this photo of the radio control model. From the larger writing on the box ( which I can just make out ) it says it uses the Cox 0.049 engine and a two channel radio. I would suggest this is not going to be much use today for anyone to learn to fly r/c given what is now on the market. I'm guessing this came out in the 60's or 70's but that is just based on the c/l models. I think it unlikely anyone on here will have personal experience of flying one ( but you might get lucky ). Based on what the c/l ones now can go for, and pending the condition of yours and completeness of the contents, you may have an item of fair value to a collector ( if you are thinking of selling ).
