Well, on 12th July 1979 some people in Western Australia got pieces of the real Skylab.I was into Skylab before it was cool.
|Recommended Engines||C11-3, D12-3, E12-4, E12-6|
C11 vs D12 will be underwhelming. Lower initial thrust, shorter burnI need to get some to compare - like against a D12 or C6 engine.
If using the 29mm BP motors by estes, build light. They have low thrust for their sizeApparently, I need 29mm motors too!
Yes.I went to the engine prep section on the last page of instructions and noticed for this rocket, to wrap multiple layers of masking tape at the end of the engine 1/4” up from the end. Is this supposed to be the “engine stop”?
thank you so much for the quick reply! I didnt even know there were composite motors I could use. So after doing some research, im not sure if I can use the AeroPack 24/29mm adapter if I already have the Estes 29mm retainer epoxied to the engine tube...or will it work and I just cant use the Estes screw on cap with the areopack adapter? The areopack adapter states i need to use the 29mm aeropack retainer. Needless to say, I am very confused now lol. My original question was answered about wrapping BP engines with tape, but now, like you suggested, I may want to go the composite motor route with this Saturn. Could you explain to me a little more about this method please and what I may have to do to convert my current setup? Sorry for the newbie uneducated questions!Yes.
Although I can't speak for that kit in particular, the technique of wrapping tape around the end of the motor is common for using black powder motors in rockets without engine blocks in them (this is usually called a "thrust ring".) Composite motors (excluding Q-jets) typically have the thrust ring molded into the case.
The purpose of leaving out the thrust ring is that it allows you to more easily use different-length motors, at the cost of needing to do a bit more prep work when using BP motors.
If the Skylab Saturn V is anything like the regular Saturn V, it is better off with a higher-thrust composite motor anyway. I think the Aerotech E30-4 would be a very good one to start with (with 29->24 mm adapter). Others who fly the regular SatV can chime in with more details.
Indeed. The safest motor is the one that gets the rocket off the pad more quickly, maximizing the chances of a vertical flight. Any motor will work fine with the Estes retainer (again, using tape thrust rings with BP motors).IMO, the F15 is the riskier motor.
Looks fantastic !!I just finished my Saturn V Skylab and have a question. All of the other model rockets I have recently built with my kids all have engine blocks in the engine tube assemblies. And while I was admiring the hours and hours of construction and hours of paint on my Saturn, I thought about the engine tube and how there was no engine block supplied or displayed in the instructions! I went to the engine prep section on the last page of instructions and noticed for this rocket, to wrap multiple layers of masking tape at the end of the engine 1/4” up from the end. Is this supposed to be the “engine stop”? Please help as my OCD is kicking in bad! Thanks in advance! And I threw in a picture of my finished product! Cant wait to launch this beast!

All of them.I guess after getting all these supplies for 1 rocket, I may have to buy a few more larger models. Any suggestions? Thanks again everyone!
There are so many choices! Sticking with larger Estes kits there’s the #9719 Super Big Bertha, #9720 Doorknob, #1295 Mean Machine, #7260 Protostar. Going to other vendors of LPR/MPR kits - Aerotech, North Coast Rocketry, Madcow, LOC Precision - all have great kits in the 1.6 - 3” diameter range, too many to list...check out a couple of websites like Apogee.com, eRockets.biz, Siriusrocketry.biz, buyrocketmotors.com... I’m sure others can make some great suggestions as well.Thanks everyone for sharing your great knowledge with me! I found out that I can use my ESTES E Launch controller for igniting composite motors as long as I use ESTES sonic igniters. So I ended up just buying the ESTES Porta Pad E launch pad which comes with a 1/4” launch rod. Bought some E30-4T composite motors, ESTES Sonic Igniters, ESTES 24/29mm engine adapter, and some 1/8” ID 1/4” OD silicon tubing so I can use the 1/8” launch rod on the ESTES E launch pad for the smaller rockets...anyone going to need the ESTES Porta Pad ii Launch pad with the red launch controller? I guess after getting all these supplies for 1 rocket, I may have to buy a few more larger models. Any suggestions? Thanks again everyone!
