Quick Question on Model Rocket Engine prices in Australia

Just paid $23 for a 3 pack of Estes C 6-2 size @ Willetton in Perth. They are cheaper at

Fat fingers - correction - about $19 at Stanbridges.

No wonder you pay so much -- the C6-2 must be a special order item...

In addition, we would be providing 90sec per metre green visco safety fuse in addition to electrical igniters.

This is sanctioned by NAR, TRA or the Australian counterpart?

FRAK!

I will never complain about engine prices again!

Sorry, I wouldn't have a clue what engine types others are using.

The engines I purchased are the first I've ever bought. Took our sons & our home made rocket (PVC conduit, stuck on fins & balsa nose) out this morning for its inaugural launch. Excellent fun, guesstimate 150+ metre height. After four engines we called it a day and went home to glue the fins back on.......

After the fun & success we had I'm real glad we didn't fork out Au$50+ on a prefabbed rocket.

Randy - not sure if it matters but the $23 for 3 engines is in Australian dollars, roughly eqiv to US $16/$17.

I forgot to note that I was talking Oz $. rob

Still, that's about 3-4 times normal price here. Sheesh! Is it the shipping or the tarrifs?

About 9 years ago and before 9-11 and all the ATF garbage, I sent a boat load of stuff to Tom Matley at New South Wales Rocketry Association - kits and A-C motors, D's were a little more, seems like the local price there was about double at that time. It did take about 30 days to get it all there. I used regular mail.

Almost seems y'all could order and ship from the U.S. for less.

If only it were that easy these days :) These days, you have about an

It's the DG shipping (if you can find anyone to ship them!). We were going to order AT RMS motors direct from the US but it turns out we would only save about $5AU per motor once shipping was included.

Depends ;-) From $15 to $2000

In australia? Hmm, hard to say, but I would guess there are about 30 or so people using Aerotech motors and around a thousand or so using estes type motors.

Since most (if not all) motors come from Dawn Trading (hobby wholesaler) just about any hobby shop can get them. I am buying from Toyworld at the moment.

Don't bother. There's that many on the shelves, I doubt you could be competative.

On estes motors? No. Definitely not. Aerotech? For sure. There has been a supply problem (I think that may have been resolved). If you can do aerotech motors cheaper than dawn trading...I paid $32 for a G64 (they were $29 last year!).

Hmmm - I wouldn't....2 reasons: 1: It's not approved for rocketry use because it's dangerous for model rockets - once it starts burning, you can stop it safely. 2: I think you will find it is illegal in many states without the required permits (that WILL be the case here in WA). Dont do it - it's too dangerous and people who play with estes motors are mostly clueless as it is (like our PVC rocket friend here).

Most people will be using B4, B6, C5 and C6 motors.

We dont have an 'NAR', It's not permitted with TRA and you will need a pyrotechnics permit in mostr states to posses this stuff.

Good job you still have a son. Do you have any idea what could have happened with your PCV rocket? You are lucky no one has hurt. Just because something looks like a rocket, doesn't mean it will fly.

You should check out some video of when rockets go wrong... But if you must build your own rockets, at least take 5 mins to learn about rocket stability and max lift off weight for motors - it could save yours or your son's life.

Do Australian rocketry a favour - don't include this stuff. It's too dangerous for rockets. If something goes wrong (and it does happen) and you have to abort the launch (been there, done that) you are in trouble if you use fuse. As I said, most people using estes motors are mostly casual flyers and they take enough risks as it is.

keep reminding everyone: model rocket motors are NOT explosives!!! yeah, they burn fast, but they do NOT explode!

Cliff,

While they contain fuel and oxidizer and are class HD1.whatever they are explosives. Some just deflagrate rather than detonate. BP can detonate under the wrong (or right depending on your view) conditions or stimulii.
