Rather than pontificate I will simply post this where the TSA and a security expert trade their views on the overall effectiveness of TSA prior to this ruling:...

I was told this was for retention. You can use a Kaplow clip type retainer that has a hook style retainer with the holes - without them it's hard. I have the older Pro54 closure which does not have...

RockSIM works also. RASAero as well...

You can also go to www.rocketreviews.com and see if the CP/CG is listed in their resources.
Cardboard Cutout method is another way - not very good but...

The 81mm (Hammerhead) has not been common for a while. The 54mm is a lot longer but easier to manage for most airframes.

I wish you had a blog where you could detail the "service" you have gotten switching carriers. I hope the new carrier is better once you have all this resolved.

Don't forget ROCC? I think you are still attending our launch on 3/16 - correct?

Update - Ken's phone trouble is still not resolved however he now has an alternate phone number: 202-241-0157
Ken mentioned he was trying to post this new number to the website but when I checked...

Was the less than 9v measured with load or without? A 9v should measure higher than 9v when unloaded - anything measuring below 9v without load might be pretty spent. Had this combination of low...

I just updated the thread title as it occured to me that not everyone knows Ken owns Performance Hobbies.

Wednesday or Thursday of this week (Today is March 2nd) Ken Allen attempted to swtich his phone service and had problems. As of Friday this was still not resolved and he had no other phone to fall...

What is your home field like? That L2 shot sounds like it will be waaaaaay up there. Do you plan to have tracking gear in the rocket?


What does this part mean? Are you just saying you are...

Another option for future builds is to look in the wire section for the clamping u-bolt shaped things they use on stranded wire. If you remove the U shaped clamp and just use a couple of flat...

The big problem with this is akin to my qualms over the explanations for quantum mechanics. "Observation" like "decision" is something without clearly defined parameters. Furthermore, there is a...

Add spin tabs - essentially add small wedges on the back ends of each fin - this increases rotational energy and stability at the expense of altitude.

Paint with Flecstone (spelling?) - textured...

I had that happen with a rocket recently same brands. I also had it happen on a pinewood derby car - luckily I was able to fix it in both cases. By sanding!

Nu Finish may be in my future. I've...

I would HATE it if we had that TV or if god forbid a neighbor did. I have already had enough of the noise from the outdoor speakers people feel compelled to use without any inkling of how far they...

Oh well... if it was lower I might but I can buy the sheet as you mentioned and pick it up for less than half again that amount. I was hoping I was closer from a postage perspective. Dang.

There are some awesome clamp on versions in that list.

Would you find out what this will cost to 28227 and let me know?

If you already tied it at the initial point tying it now isn't going to weaken it much. I would either tie two loops and use a quick link if there is any value to being able to remove the extra line...

I keep looking for the LIKE button!

If it were me - I would have said, length, diameter, manufacturer and very close average thrust... and aren't they both black powder?

I am glad someone else pointed it out. In this case the difference in meaning is funny. A Duel deployment could mean that the two chutes fight... it could also mean a drag race type contest with...

Chris - I'm a customer of Ken Allen's in person at my home field. But I have purchased from you in person in Manchester TN before and would gladly do business with you if I needed something that Ken...

I have friends who have flown Transolve's for years without issues. The Adept may be more reliable but if you use a reliable switch and you test your setup a few times carefully you should be OK.

In a pinch you can use a couple of 6v lantern batteries tied together in series. However these are not rechargable and will cost more in the long run.

Great idea - expanding on this - you can get a case that allows you to use the Hard Drive as a USB external hard drive.

This has to be one of the best out there. Also if you want after you get the CD built you can use the CD to build a USB bootable drive also. You'll need someone...

Are you saying your fins are too far back? That would increase stability not decrease it. I may be misunderstanding what you are saying.

They make devices that work pretty well for joining this stuff - they are used in industry for a completely different purpose but I have seen them used once or twice on short rails to make them...
