FAQ

How do I join the club?

Membership in ORG costs $30 per year for adults or $5 a year if you’re under 18. Dues are payable when joining. You can join the club at any scheduled launch (or at the AGM, usually held in late October, early November.) Guests are free and your first visit is also free. Just bring your rockets and motors, we have all the launch equipment required.

When is your next launch?

We generally fly every two weeks on Sundays subject to weather conditions. It is important to either join our Facebook Group or our Yahoo mailing list in order to receive a Go or No Go call in the morning on the day for our scheduled launches which listed are on our Calendar

How to get there?

As we are visitors that have been granted access to a secure installation to enjoy our hobby we have a controlled access procedure to follow to get to our launch site on launch days. Please READ and follow the information for Launches Entrance . Please note that you need to be on time to access the range since it is in a restricted and gated area. If you are late, Range Control will NOT grant you access.

Can I arrive later?

No. The Connaught Range and Primary Training Center (CRPTC) is an active military facility. Our launch field is in a gated area with locked gate. If you are late, Range Control will NOT grant you access. Please note that once at our launch site, we can’t see the entry gate. Also all flyers and spectators need to attend the MANDATORY safety briefing before the start of the launches.

At what time are you done? When can I leave?

We have the location until 16:00. We fly until people are done, normally mid-afternoon. You are free to leave at any time. There is a button inside the perimeter to open the gate to leave. Please respect the speed limit on the base.

Can I use the field by myself at other times?

No. Our field is the grenade range at the Connaught Range and Primary Training Center (CRPTC). It is primarly used by the military and the RCMP. The club is fortunate to have access to the facility for free on a regular basis. You can only access it during one of our scheduled launch.

Is your club still active?

Please rest assure that our club is active. This web site is maintained by volunteers, so it is not updated frequently. The best way to see what we are up to is to have a look at our Yahoo discussion group or our Facebook group: Ottawa Rocketry Group

Can I fly home made motors at an ORG launch?

No. You need to use commercial motors at our launches. We do not host Tripoli Research launches. We are not aware of any Canadian clubs holding Tripoli Research launches. Some Tripoli clubs in the US hold Research launches. Please note that you need to have a valid Tripoli level 2 certification to launch non commercial motors at a Tripoli Research launch.

I want to make my own motors. Can you help me?

No. The Ottawa Rocketry Group doesn’t encourage or support the manufacturing of solid rocket motors by amateur rocketeers. Accidents can happen even if you are a professional, see PEPCON disaster and CTI fire.

The following information is from one of our member who has a PhD in Chemistry:

“Many rocketeers at some time consider making their own motors. “Experimental” motors built by experienced high-power rocketry enthusiasts are becoming increasingly popular in the US. The two essential elements to be considered are SAFETY and LEGALITY.

Rocket propellant chemistries necessarily involve unstable and energetic compositions designed to burn in a way that maximizes the production of hot gases. Accidents with propellant compositions and the materials used to formulate them have resulted in serious injuries and death. While cured APCP (ammonium perchlorate composite propellant) is quite stable, safe to handle, and burns rather than explodes when ignited, intermediate mixtures of finely divided dry powdered components can be very hazardous. Many intermediate compositions burn with breathtaking speed so that there is no opportunity to retreat. Casual experimentation with formulations can generate compositions that can detonate upon ignition. The magnitude of the hazard is directly proportional to the amount of material being processed and to the proximity of the process to people and property. The risk that the material ignites unintentionally is inversely proportional to the extent to which sound practices are used throughout. This risk can never be reduced to zero, even when managed by experts.

In Canada, the manufacturing of rocket motors is governed by the Explosives Act and is generally prohibited. Recent changes to the Act allow for the manufacturing of high power motors for personal use by individuals holding a Manufacturing Certificate for this purpose. Application for a certificate can be made to Natural Resources Canada, Explosives Regulatory Division.

On the PRACTICAL side, making useful motors necessitates being able to measure their performance (thrust curve) and make them reproducibly. The wide range of commercially available high-quality motors with well-defined performance characteristics makes this the best approach for most rocketeers. In general, low risk approaches to manufacturing motors require significant investment in equipment and dedication of space so that making motors to save money is not a winning proposition. If you do decide to pursue an interest in experimental motors, make sure you start with a solid understanding of the materials and hazards involved and the practices required to best minimize risk. Insurability of losses in the event of an accident, even with a manufacturing certificate, is unclear.”
