Rms 29/40-120

Tons of people ask me what is a Rms 29/40-120. An Rms is a cheaper alternative to single use engines. Instead of buying an engine already built you buy a metal case and make the engine your self. This doesn't mean making the propellant. You buy a reload which has the propellant in a paper tube it also comes with the other parts to make the rest of the engine (ejection charge,delay, etc). Instead of buying a single use engine you just assemble the engine into the casing. The main reason I want to get it is because a reload for a G engine costs $8.00 and a single use G engine costs 22. The Rms can hold E, F, and G engines. This would cover all of our engines we need for mid power rockets. They are cheapest at hobbylinc.com

Previous launches

Naive launch:
this was our very first launch. Most of our rockets were the inside of tinfoil tubes with cardboard fins and rolled paper nose cones. Most of our engines were C11-7s and C6s. Most of our rockets didn't work. Our grand finale was a two stage. There wasn't a butterfly just a D12-0 and a C6-5 taped together. Of course it didn't work and spiraled out of control. Even though our rockets really sucked we had a great time.

Titan launch:
This was our first launch where we had more successes than fails. We ordered from Quest and got body tubes and tips we thought this was so professional. Most of our fins were frame board triangles. All our rockets were minimum diameter and were spray painted red. Most of the engines were C6s and Bs. Our grand finale (the Titan) was a 25mm tube 3o inches long with a D12-0 and a C11-7 taped together the idea was the D would light the C and that would burn through the D. The C11 slid up and set fire to the upper body tube.
Kaelan's rockets weren't minimum diameter. they were long, tall and skinny. All of them didn't have recovery devices. The egg carrying one was fun to watch as it fell to the ground and crashed next to my car.

The July launch:
By far our biggest and best. We all ordered from quest again and Simon and I got a 35mm tube and tip. We made our Goliath rocket its the one below with the golden tip and red fins. Kaelan's big rocket was called the Havoc. Both of them flew on D12-5s. All three of us saved up all the rockets we made in the last 3 months. Simon and I had over 20 and Kaelan had 16 or so. We went out to pony express testing range to shoot them off. It was a great launch.

Hellfire 15

This was my first time seeing high powered rockets. The audio an the camera doesnt say anything about how loud these rockets really are.

Uroc sport launch

We flew the gladiator here. It was a great launch.

The Gladiator

At hellfire the three of us got a 2.6in body tube and tip. We went to hellfire not knowing what it was going to be like. Previously Simon and I decided to make the jump into mid power rockets. Our original plans were to get two bt-60 body tubes and a tip. We would fly it on a F32 (a huge jump for us from the A-D powered rockets we would buy) In the discount rocketry trailer Kaelan and simon were trying to convince me to get it and I was very hesitant. Finaly I agreed to get it. The body tube was 34 in and the tip was about 13. After I bought it I was thrilled. We planned to fly it on a F32 but when Simon and I found out how high it would go (600 feet) we wanted more power. Simon was hesitant to go straight to G power (a long way from the Cs and Ds we were so used to using). We both weren't sure we could handle the power of a G. At about the same time we made the fins out of 1/8 inch plywood. Kaelan did all the designing and his dad cut them out with a saw. The same day we cut slots in the body tube. Kaelan, Simon and I agreed to fly it on a G38 (that seemed to have enough power.) After the fins came the engine mount and parachute. Simon and I looked up how high the rocket would go on a G38 (1000-1200 feet) I asked kaelan what he thought and he wanted even more power. We were looking at a Rms 29/40-120 that looked good it would provide a F engine as a first flight and a G engine as a second flight. The new engine we planned to fly it on was a G71 redline (intense red flame) Simon and I were both hoping to get it for our birthdays but we didn't so we went for plan B to order the one we were looking at. The estimated arrival date was later than the October sport launch that the local club was having. We went and brought the gladiator anyway. There we saw a single use G77 that was looking really good to us. It cost $22 but we decided to split the cost. We were very nervous and excited to fly it but it worked great. The parachute didn't open but it came down without a scratch. Click here to watch the flight.
