I need to do this too.I have a router and table, but no jig for “dead-on balls-accurate” cuts. I would be interested in the answer too.

What do you think for the fin tab servo control???http://www.futaba-rc.com/gyros/futm0830.htmlhttp://www.futaba-rc.com/gyros/futm0807.htmlI am hopeful…A retired designer/engineer contractor for NASA…also a model train buff I met here at Caboose hobbies suggested this……

There are several RC airplane products that have GPS-based “return to home” functions that work with the aircraft servos. Getting the mechanical part right is the hard part for rockets. I’m starting to lean toward a deployed wing + low… Read more»

When fin allignment is not perfect, the wind is a bit strong, and you want to keep the nose up during the coast phase……..There has to be some pirated IC plans for enhanced flight control systems…some where…with all the miniaturization/mass/microgyro… Read more»

Tthat is a neat idea!. I can easily imagine hinged payload doors similar to the STS. The ejection charge is set off, the doors open, and the parasail comes out. The shape of the sail could be altered, as the… Read more»

An all-mechanical solution would be cool in a retro way.My own project that may come up to the front burner sometime this season is a GPS-based, self-returning rocket. I have a cheap RC paraglider canopy on order that should be… Read more»

Back around 1971, I took a large Centuri Little Joe II, made for an Estes “D” motor, made a payload bay extending from the nose cone into the body tube. I mounted a 4″ diameter toy gyroscope in it with… Read more»

I’ve been thinking about this for a while as well. I have some micro servos that I’ve been playing around with for a gimbaled motor system.Warren as you point out, you would need a lot of flights to characterize this…. Read more»

Sparkfun has a 9DOF board – 3axis accelerometer, 3 axis rate gyros and 3 axis Magnetic (compass). That plus an Arduino or other small micro-controller and servo-controlled fin tabs might make a dandy little project. The only weakness is the… Read more»
