Understand your concern...but you know 250 is not bad. Issue is will all 3 chutes deployed and I for one always consider changing out the 2 chutes on the body for just 1 chute.....either the 24 incher or a larger one. BobbyG23 did a built thread last year and after crashing on an E12 ..he tried a E30 and like the result. Check out his build thread.....search Saturn V build thread.OK OK I mis-spoke I know CG is above CP.. I got it. I've been busy with life but let me answer a few questions. I figured out the CP with the cardboard cut out I have not ventured into the rocksim but now I know I will have to. So if I have a proper CP and it is below the CG and I put in the engines Estes said should work and the sale of the rocket is based on it it will fly. I did not overweight mine I did not slop paint on it I did not attach heavy metal objects to it but it would not fly until I experimented with larger engines then Estes called for...That's my point..... I balanced the rocket to acquire the CG with everything loaded on the rocket like it was going to fly. I was not using heavier motors then suggested and yet it was underpowered.
I understand about the F24 Aerotech motor and you load it I got that and have one but not to that stage yet. I don't want to get into it but someone mentioned about cg being in front of cp by one body diameter tube size if you do that on a Saturn V you have to add a lot of weight into the nose to make it stable and now how is that to have been flown out of the box with the suggested engines. Kits other then Estes provide a cg if built as shown, Estes gives no advice or any info on cg or stability???? I'm on some other thread about my two versions of Saturn V and the amount of weight you need to make it stable by the information you have provided, rocksim or no rocksim now its so heavy trying to get off the pad and reaching 250 feet and this is on an Aerotech engine. Ok one area I need more understanding cause trying to read about the aerotech engines the different blue,white,black.. and all the numbers given and how one article talks about power to get a heavy rocket off the pad but it does not have p-ower to accelerate, or this color will accelerate or for heavy weight, so ok what numbers are you using to get a more powerful engine(one that will liftoff the rocket and accelerate to a safe altitude with ample room for the delay to happen and then the chute to come out and not make a hail Mary landing????? They have numbers in 8 different categories and weight of max liftoff??? so how do you look at all the numbers and say this has enough total power to launch this rocket. I used a E30-4T and it got the Saturn V to 250feet, but I wanted more room and so I tried a F44-4W and a F32-4T but these did not increase the altitude what so ever so I might as well use a E30 Aerotech so what did I read wrong and how do you pull out the real number of these engines other then by experimenting...I'll take any advice. Ok enough for now
