Well it's not all AV, but it sure makes for a cool video!

not only illegal, against all FCC rules, but downright dumb.out of control, fire?? and, no, not cool

SAVS

I'm still laughing! I think it would only be illegal if he had a camera on board and was selling the pictures

Motions

Not sure how this is considered illegal or what the FCC has to do with it at all but is was pretty funny. Not the smartest thing to do but when are smart videos funny?

Does the FCC cover Alberta Canada or do they not have TV there yet ? [sm=spinnyeyes.gif]

I conducted rocket assisted takeoff #5 with the Aerobird Xtreme today. I configured the camera for an onboard aft facing shot to showcase the rocket engines as they propel the aircraft through the air. For this launch I used four "C6-5" engines configured for pure forward thrust ignited just as the aircraft was ready to rotate for takeoff.

Enjoy!

De-Luxe!!!

I wonder how many rocket engines you can get on it and still remain in control???

How do you supress the parachute charge at the end of the burn???

Cheers, e-PSF

The most engines I've mounted so far is four "C6" Estes engines. If I really wanted, I could probably mount three more, but it makes more sense to just upgrade to a more powerful engine. I'm waiting on a nice day to try my next configuration which will be two "D12"
engines, which should be equal to the [link=http://www.youtube.com/watch?v=hkmW-dz3a_Y]four "C6" launch[/link]
The parachute charge is supressed by making it easier for the charge to exit out of the nozzle rather than the front. I do this by simply wrapping the front of the engine with electrical tape to form a sturdy plug. Of course an easier solution is to purchase booster engines that have no parachute charge.

I loved your videos! Can you tell us precisely how/where you mounted the rocket engines and how you ignited them?

kd7ost

It's not illegal in the United States either. AMA (Academy of Model Aeronautics) rules even allow for rocket assist take off and or JATO.
Read rule 8. http://www.modelaircraft.org/PDF-files/105.pdf

The FCC is the Federal Communications Commission. I don’t think he provided any information that would lead us to believe he’s operating on an illegal frequency in the United States where the FCC operates.

There are models you can buy in the hobby shop from Estes and other companies. They are RC rocket planes and are not against any law.

Cool videos.

Thanks!

As for how, a little knowledge of electronics and aerodynamics coupled with some trial and error...
Is that exact enough for you?

Seriously, you will need a radio system with one spare channel and a remote controlled relay like this one [link=http://www.dimensionengineering.com/BattleSwitch.htm]Battleswitch[/link] to ignite the rockets.
I found it was best to mount the rockets at a 45 degrees down angle at approximately the aircraft's centre of gravity. Where and how to mount the rockets exactly will depend greatly on the particular aircraft. I used tyewraps and carbon rods.

...anyone try them with an aero ace?

Gigaah

Probably don't need a remote control relay. just and extra servo on an extra channel. glue one wire the the servo arm. glue the other to ..somewhere..and just make it so when you move that channel it connects the two wires. bingo! gheto radio control relay.

Lucas!

Yup as stated before this is legal. It also does not break NAR (National Association of Rocketry) rules or AMA (you know that one) rules. I belive according to AMA rules you can use up to a "G" engine. And I have no idea how you got that it was against FCC rules. And fire.... ? there was snow all over the ground

Looked like he did it about as safe as possible.
- Remote ignition
- Open Field
- Facing away from him
- Nothing that could catch fire (snow)


Very nice!

More questions regarding setup... did you use the Xport chanel for your rocket ignition? If so, how did you get that to work?

Riverman

I didn't use the X-port as I upgraded to a 6 channel system that affords me the benefit of several spare channels

Cheers

Hey man.. Awesome video. I'm still laughing. If I didnt love my stryker so much, I would be planning an evil plot such as this. More videos!! And if you manage to catch the snow on fire..... Please post the vid! lol

Riverman

Thanks!

I've been on a rocket assisted flight hiatus but as soon as I do some more vids I'll deffinately post 'em!

Cheers
