I am building a large scale model airplane, and I am in need of help with a circuit for the strobe lights. I want to make them wide angle white LED's. I have some electronics experience, but very little with timers and LED's. I am able to make one work, but the pattern on the full scale airplane is different. There are 3 lights involved. I need the wing tips to flash first 3 times at about a 3-4 hz rate, then I need the tail to flash 3 times at the same rate. There needs to be somewhere between .5 - 1 second between the wings and tail. Please help if able. Thanks.
