Jolly Logic provides some really neat items for the rocket hobby enthusiast. They have three kinds of small altimeters that can be placed in the payload section of your model rocket and record some neat and interesting flight perimeters. The altimeter three can pair up with your smartphone utilizing an application that can be added to your phone. after a flight, you can pair your phone with it for immediate data and then email it to where you would like to share the data. They also have a parachute release mechanism that does not require any pyrogen for deployment.

I have had fun building some model rocket boost gliders recently. Edmond Aerospace used to make some fun 
and easy to build gliders that were crowd pleasers.
Hood River Hobbies carries Flis Kit model rockets and if they do not have a kit your see there, they can special order it for you. I bought the Nantucket Sound kit from them and had a lot of fun building it. I checked out the Fliskit web site and noticed that they also made a Micro Maxx version, so I bought and built the little light house as well. Flis Kit models are like the traditional kits that Estes and Century used to make back in the 70s and 80s. I will have to launch the bigger lighthouse at the next launch in March of 2016.
