Rockets in build
The following rockets are currently being built.
GP4With the destruction of the D-Region Tomahawk, we needed a new rocket as a general-purpose Level1/2 workhorse, and the GP4 was born. Based on 4-inch Quantum tube, the rocket is designed to be resistant to knocks and general wear and tear, and suitable for a wide range of motors up to 38mm diameter.
This does mean that it isn't as light as it could be, though, so 29mm hybrids are probably off the menu. The fins are well clear of the ground on landing, and of course are the through-wall variety. An altimeter bay is fitted for hybrid flights, but composite motors can also be used.
