>for home built rockets.The highest on a scratch-built: 2600 feet on a 6 inch diameter, 10 foot long, 22 pound lift-off weight, 4.5x upscale of an old Estes kit called the Interceptor. It flew on a cluster of 3 I284 reloadable motors.
Highest on a kit: 3500 feet in a Rocket R&D ARCAS (4inch dia, 8 feet long, 8 pounds liftoff weight) on a J350 reload.
There aren't records specifically for scratch-builds. Most records are based on motor class. I'm not sure exactly where you can check for a list of records, but you can start at the NAR website at http://www.nar.org or at the Tripoli Rocketry Association site at http://www.tra.org
The best you can probably hope for using Estes motors is around 1500-2000 feet, single stage, but that's usually in a scratch-built rocket using exotic materials such as vellum, G10 fiberglass, mylar, vacuformed plastic nose cones, etc.
A company call Vaughn Brothers has a series of rockets called Extreme that are minimum diameter rockets for different size motors. I think the smallest is the VB Extreme 13, that uses 13mm Estes mini motors. The largest is the VB Extreme 54. It uses 54mm diameter motors such as the L750, K550, and K1100. I believe on a K550, it will reach over 13,000 feet. Other rockets have been built by other people that can routinely break 20,000 feet and even tickle the 30,000 foot mark.
