We had yet another one Loop-de-loop today at the MC2 launch.
Ever considered stamp collecting?

We had yet another one Loop-de-loop today at the MC2 launch.
Seems like a personal grudge against it. He has said nothing for weeks as this thread has been pretty dead and first time someone says something positive out of the wood work he comes and spreads more negative comments. I have has 12 flights NO issues or problems. jahall4 please spread the negativity else where and let us enjoy this rocket in peace. You have made you point WELL known but you seem obsessed like a sickness. Its gotten old and tiring. Enough please!!
Just coincidence my man. It's only the 3rd time I have seen one fly and this one was NOT flown by me. For you to interpret something different suggests your own personal bias and sickness. I report what I see to benefit those trying to fly this rocket safely, you trying to make it about something else suggests that you have little interest in the safety of the hobby and should not reply to post you don't like.
Coincidence perhaps... I apologise if I offended.
Accepted or not is your choice of course. Poor choice of word on my part. I did however mean it sincerely. Life is too short. I can only say what I have experienced with my 2 Saturn V 1/200s. I have had no issues any only good results in over 15 flights now on recommended C6-3 motors. This is a great hobby and it is important to report issues with products. I do however feel there are no issues with this one. Maybe a few were improperly assembled in the factory causing issues you have witnessed or bad motors. I have had great success flying mine and look forward to many more flights. Nothing like seeing a scale Saturn V lift off.
Very true but it was addressed with the addendum and if followed no issues should arise.
Never had a issue myself with the C6-3 which is alI I have used. I am curious to try a C12-4 Q-Jet when they are approved for sale here in Canada.
Yes, the adendum does a good job explaining how to avoid an improperly loaded motor, but the flight on the 7th was post addendum, and as I explained at that time, flow by a flyer that a) was aware of the issue and b) may have more decades in the hobby than you and I combined. The C6 is simply not adequate (by calculation and by Estes own guidelines) made even more so by an individual motor who's thrust may be as much as 20% below spec.
The thrust level of the C6-3 is not what will cause an unstable flight.
Sure it can hence 3-5:1 T/W ratio as a min rule of thumb, but yes, at such a low ration thrust alignment is critical and even more so as the margin approaches 0.
Has anyone considered using this?
Seems like a lot of folks thinking this model is under powered with the C6-3
Flight Sketch has a kit to go from the 18mm stock motor to a 24mm motor for this model.
Has anyone tried one yet? Instructions look interesting.
+1. Maidened mine on a D16 Q-Jet. It flew straight as an arrow and promptly drifted out of the park.Absolutely no need.
Perfectly stable flights with C6-3.
If you want faster flights, you use a C12-4.
If you want even faster and higher flights, you use D16-4.
No alterations required.
...man - sorry for your loss.+1. Maidened mine on a D16 Q-Jet. It flew straight as an arrow and promptly drifted out of the park.
Lost it in some scrub brush.
Replacement will fly on a C12 or C6.

Ouch! Pricey model to lose on the first flight. On the other hand, since it is RTF, at least you didn’t lose hours and hours spent building and finishing a kit version.+1. Maidened mine on a D16 Q-Jet. It flew straight as an arrow and promptly drifted out of the park.

Kids had a altitude plastic thing and said on most of the launches I was getting almost 700 feet, to 800.
I have modified that to a better version with a quick lock motor retainer. You don't have to modify any of the original parts (Other than adding nose weight), just replace and go. Download the 3d print files instructions and photos here: Look for the Saturn V Zip file. And enjoy the other videos n stuff!Has anyone considered using this?

Make sure the Qjet igniter is all the way to the front of the motor. Composites burn from the front of the core, if lit from the middle or end they might not build up enough pressure and will stay on the pad and burn.Launched my Saturn V on Saturday for first time on C6-3. Actually flew better than expected I guess it went 200' but seemed higher.
Attempted to fly on D16-6 but malfunctioned. Motor burned for about 10 seconds and after 6 second delay ejected parachute. Rocket never left pad.
2nd attempt on D16 and could not get to ignite. Igniter popped with authority but did not ignite motor.
