Extreme Performance Whistle Rocket Kits

Extreme Performance Whistle Rocket Kits

These whistle rockets were developed with the help of Jim Biersach. We started with a clean slate and the goal of seeing how much performance could be achieved with whistle mix. Starting with an extremely long spindle, we had nothing but chaos at the beginning. Gradually shortening the spindle after each test, we finally settled on a spindle length that gave a bullet-like performance - nothing but straight flight, with no rocket lay-over. Initial take off is like trying to watch a bullet. This is a real winner!

The kit comes with a stainless steel spindle and aluminum base. 4 oz and 8 oz kits come with 2 rammers, while 1, 2, 3, 4, and 6 lb kits come with 3 rammers for proper length and a steel puller. We also recommend that you use a Spindle Puller with this tool.

Jim Biersach recently made a 4 oz. Extreme Whistle rocket using a 3-ton Arbor press. It flew like crazy. Needless to say, he was excited.

I want to thank you for the unbelievably quick turn-around on my orders of discs and 3" case former! Look out New Year's Eve! In all seriousness, it's too bad that all on-line companies of all types don't have your pride of workmanship sense of duty toward your customers.
