Isaac's "New" Hobby

Several of Isaac's coworkers are really into remote control airplanes. They design their own planes, cut the foam on a special machine, and order in the parts. On breaks during work, the guys will all go outside and fly their airplanes around the building and have competitions who can keep their airplane up the longest with the engine shut off. Isaac has been working really hard on his plane over the last month designing, measuring, weighing, and planning out each step. He finally put the finishing touches on it and took it on its maiden flight a few weeks ago. It flew beautifully and he couldn't stop smiling. Since that first flight, he has continued to make minor adjustments, and he has been able to take it to work, the park, and even fly it right outside in the back yard. Each time he flies, he can't seem to get enough and his smile gets bigger and bigger. I would say that it is his new hobby, but considering that anything to do with airplanes has always been a hobby of his, we will just have to say it is his recent hobby, and I have enjoyed watching him get so excited over each step of the process. Here he is with his finished (for now) product.
