Re: Quest C6-3 Motors - Any good?

Think I’ve only flow their B motors, used to get them in packs of 6. Never had any issues, the diameter is a little less than Esties and I suspect a little lighter.

Re: Derek's Level 2 Build

My CAD skills are still a bit ordinary. I sometimes have ideas in my head that I can't translate into CAD designs, but I am slowly improving. Sounds like where I am at. I drive SolidWorks like a Neanderthal I think, but a bit of head-scratching gets me where I need to go in the end :) . Arg! You gu...

Re: Derek's Level 2 Build

Looks like it will do nicely for a cert flight. If you add fibre glass it will put the weight up, might want to plan on bigger motors.

Re: School Rocketry Club - Ejection System

As OTT said the easiest way is to use motor ejection. If you really want use an electronic mechanism then Air Commander has a bunch of information on doing this in a number of different ways, but it is based around using a typical water rocket body. While you can use a timer for deployment, I would ...

Re: Boat tail fin can

Hi All I've started on a 4" vehicle design that includes a boat tail for base drag minimisation. The addition of a boat tail makes significant improvements to the simulated altitude and the motor this vehicle is based around allows for a nice boat tail implementation. The current overall desig...

Re: SpaceX details its plans for landing 3 Falcon Heavy boosters

That came pretty close to landing. To me it looked like it hovered maybe 30 meters off the deck and veered off away from the ship.
