Hello Everyone,
My son and I have recently built the US Rockets "Two the Limit" kit (18oz). Its a 29mm 2-stage rocket that is setup for direct staging. My concern is that the kit was originally designed to use the US Rockets F20 motors which are not available. This leaves me with either the Estes E16 or F15 motors. I've used OpenRocket to simulate the flight of the rocket using two F15 motors and am concerned. The F15's take a while to build to maximum thrust and looks like it will be fairly slow off the rail.
Does anyone have experience with these kits/F15 motors? Any thoughts?
Thanks
