Yes, good decision on your part Andrew.
So, how did the RSO evaluation of the rocket go?
Any discussion you'd like to share?

And, I never brought my rocket to the RSO, it just sat in the car.
Thanks,
Due to some fin concerns that I have, I'm going to try to build another one. When I finish that one, I'll compare both versions.
I'm still sticking to the F10 idea.
Sims at 6200', but I expect it to hit more like 5K. If I can make it this year, I may try to fly it at MWP.
Thanks,
No I243WH?
I guess the foot-long case is kind of a pain...
Vinyl Wrap + Record Attempt?
I am willing to bet a steak dinner the extra weight of the vinyl wrap will cost you more altitude than the smoother finish it may provide would gain you.
Its possible the extra weight might cost altitude IF the rocket is over the optimum weight, otherwise the wrap might be a good way to get a smoother finish than the builder would normally do as not everyone is willing to do a polished paint finish.
There is an optimal mass. Think about throwing a feather and how far it goes. Your simulator can tell you the optimum mass and then you add extra to get it where it needs to be.
I had a rocket that was going to break a waiver. I added mass, up to about 1.5kg extra, and the altitude was still going up. I wasn't going to add any more than that stupid amount for a demo flight. Waiver got increased anyway
Fair point. I made the mistake in assuming that the rocket weight had already been optimized for max altitude (because that is what I would have done). I don't think most people who build a rocket for a record attempt come up with the idea to wrap the bird after it has been built. I would like to think that most record attempts are very well thought out before any building begins. Perhaps I am wrong.Its possible the extra weight might cost altitude IF the rocket is over the optimum weight, otherwise the wrap might be a good way to get a smoother finish than the builder would normally do as not everyone is willing to do a polished paint finish.
Go to Rocket Optimization in OpenRocket. It does all the math for you and will give you the optimal nose weight for a given motor.Yeah, the rocket is pretty light. The booster is about 1 1/2 OZ. The nose cone (without electronics) weighs around 2 OZ. So, total weight about 3 - 4 OZ, not including the finish on it.
I don't want to buy the vinyl wrap if it's going to take off altitude, I'm trying to add altitude.
I have a friend who flew an F10 in a stupidly light rocket, don't think it even made it to 4K, and he suggested me to add more weight to my MD rocket, as it might add more altitude.
Thanks,
Well, it looks like I'm going to be getting the vinyl wrap ordered from StickerShock this week!
The construction of the rocket is pretty much done.. :w:
Thanks,
Well, the mailman came today...With my vinyl from Stickershock23!! :w:

I ordered some other things for other projects along with the vinyl wrap.
I ordered one sheet of vinyl wrap and received 3 sheets!
I also ordered some decals for my rocket rocket project, "whoppins"
As a bonus I also received an American flag sticker as well!
I put the vinyl wrap on the rocket and it looks pretty good, no bumps or bubbles. It's a little uneven & misaligned in some areas, but for the most part it looks sweet!
I haven't put the heat gun to it, but will do that probably tonight.
Thanks,
what about the fins?
Got the nc wrapped. Now I just need to figure out what to do with the fins.
Looking forward to the flight!
Thanks,
