Three new rockets




These are the latest three rockets from art applewhite, and probably my last build for this year. The shiny metallic one is a 29mm cone rocket. It breaks apart for recovery. Two helix style rockets were also built. I need to make a special launch pad for them: they launch from a 1 inch long rod, and need a very stable pad that is just at ground level. One is 18mm and the other is 24mm.

Here is a video of a HUGE monocopter rocket.

fantastic! Alien spaceship testing?

Mono-copters are sweet!

where did you get the designs for that small one? How do you know if the air foil is shaped correctly for enough lift, or how much mass is need to shift the center of mass over to the lunch lung

That's one reason why they are so cool and wild since it is a pain to sim them out i do believe.

Great questions Brian.

These are both kits, so they were designed for me by Art Applewhite. You can buy them online (just google his name) and they are quite cheap.

The balance is key: the length of the wing, counter weights, and the motor mount are very important. The wing is tilted slightly, obviously it makes lift in the same direction as the motor, with some spin. The motor is also tilted a bit to give more lift, but mostly spin.

I have not yet drilled a hole for the launch rod, but it will be in the wooden square near the base of the wing on both.

These kits were not so hard to make, particularly the 24mm one (helix). Give it a shot. Dont forget to get a paper model from art also, like a 18mm cone or ufo style rocket.

Science never fails to amaze me ...

What a waste of a rocket motor :P

DTH these rockets def. do burn lots of fuel for very little altitude.

I have a similar reaction to the guys who can afford O, P, and Q motors... and simply put them in huge rockets that go a few thousand feet. That must be great fun, but comon if you have motors that could get 100,000 feet alone, and probably space if combined... how could you not go for speed and altitude?

I have the same Art Applewhite Cone. I fly it from time to time but seem to rely on my Art Applewhite saucer most often. The break away recovery of the cone is ok and the cones definitely get higher altitudes than the saucer. I just enjoy the slow majestic take offs of the saucers. Either way all of Art's stuff is really great.
