Okay. I am building a plane from scratch designs (will post about it when i complete it) and I am planning on having a booster rocket to well to boost it. The only issue i have is with my igniter system. What im curious about is, would I be able to use a relay wired to an extra channel on my reciver? If so, what relay would be best?  (voltage,amperes,etc) Thanks, Bud

How to make (or where to buy) spring loaded fins for a model rocket? Answered

I think it would look really cool if I could launch model rockets from some sort of tube or underground silo. The only problem is that the fins get in the way of securely packing the rocket in the tube. I would like to know if there are plans for spring loaded fins or if there is a place where I could buy a set of spring loaded fins.

Need advice on making a proposed rocket I've devised different to the ones seen on here, before I waste materials?

I was thinking of making a rocket and using the fuses in a party popper as the propulsion, I was going to set up 4 gutted poppers with just the fuses on a 600ml/1 or 2 lt bottle and use a string fuse attached to the popper fuses at equal distrance running into a centre fuse/string to light it and get clear.I would use skewers or something to make it launch straight up.I would have the bottom of the popper housing/film cannister against the ground/launch pad. Has anyone tried this? Would the popper/poppers just simply blow up the thing I put them in and not work? Would I be better of doing the film cannister cannon thing instead of poppers.?

The Ultimate Water-Powered Rocket!

NASA and the Air Force Office of Scientific Research (AFOSR) have launched a water-powered rocket 1300 feet into the atmosphere!The rocket was actually propelled by a frozen mixture of "nanoscale aluminium" (isn't that "dust"?) and water, pumped in at the consistency of toothpaste and then frozen in place. The propellant is known as ALICE (aluminium and ice - convenient, eh?)Earlier this month, the collaborative team, Drs. Steven F. Son and Tim Pourpoint of Purdue, Rich Yetter and Grant Risha of Penn State, Vigor Yang of Georgia Tech, Harold Bell and Frank Bauer of NASA, and Mitat Birkan and Thomas Russell of AFOSR watched as the rocket soared high into the sky, to 1300 feet near Purdue University.ALICE is generating excitement among the researchers because it has the potential to replace some liquid or solid propellants. It is a promising propellant energetically. Theoretically, when it is optimized, it could have a higher performance than a conventional propellant. In addition, because of the abundance and easy handling of the raw materials, ALICE could potentially become the propellant of choice for missions leaving other planets, since it could be (relatively) easy to manufacture from local raw materials and far easier to store than cryogenic fuels.

Cheap Two Stage rocket

If you were to take two model rocket motors and remove the secoundary charge (that pushes out the payload) from one and possibly fill the rest of the cartrage with homemade propellant. if you put one cartrage ontop the other and secured it with a little tape, would that work as a two stage rocket. does anyone think that the flame would travel into the secound cartrage and the pressure would blow out the first cartridge. Just wondering if anyone tried this before and is still alive and happy.
