Should I get the microAlt 4600 or microAlt 9200?
The main thing to consider when deciding which version to buy is launch site elevation. The microAlt 4600 is suitable for flights to 4600 feet above sea level (MSL), and the microAlt 9200 can go to 9200 feet MSL. If your launch site is in Colorado at 5500 feet MSL, you clearly couldn t use the microAlt 4600, since you would be beyond its range before leaving the ground! In this particular case, the microAlt 9200 would be suitable for flights to 9200 – 5500 , or 3700 feet above ground level (AGL). If you are launching from a field in Massachusetts that is at 300 MSL elevation, the microAlt 4600 could be flown to 4300 AGL and the microAlt 9200 could go to 8900 AGL. Bear in mind that most model rockets (G power or less) are hard pressed to exceed 4000 AGL, and 1000 to 2000 AGL altitudes are more typical.
