I may not have roughed them up enough.I used finer sand paper.With my wood fins (on some of my rockets) where the root meetsthe motor tube. I cut shallow grooves every inch or so, for moreglue to attach to the…   Read more»

I’ve bought the farm with fins that had PL attached. The PL was still attached to the fins after. I did rough the G10 up with 60 grit sandpaper though.Edward

I have a 4″ fin can/booster that survived impact from 8000’+ – built with West Systems. It has flown since multiple times with a new forward airframe and nose.

I use it on all my birds. I have used PL Premium Polyurethane on PML kits on the inside fillets with great results, as you’re bonding urethane (a.k.a. water-pipe) with it.On the other hand, I have crashed some fiberglass birds…   Read more»

The structural adhesive is very thick. It helps if the environment you are working in is at least room temperature. (in a semi-heated garage in winter it is like molasses). Thickening it with West System silica makes for some very…   Read more»

What I prefer to do is use regular laminating Aeropoxy and put some colloidal silica in it to make the consistency like Vaseline. I think it’s just as strong (though I’m not 100% sure about that), I can tailor the…   Read more»

way geeky set of posts… way awesome motor. What I’d like to see is something like a 4″ version of the motor Dr. J is building for us…. bet it would beat 330K.W

Bear,I want one of your Yagi’s. Will Arrow Antennas ship? I’d like one of your exact antennas with the exception of a ten foot lead.Do you have an address and phone number?

Wish I could be there

Thanks Ken!

Thanks Ken!

Signed up for towing round trip.

That is indeed a lot of rocket for less than $200. It is THE WAY to go if you want to do an economical L3 (my biased opinion). After many scratch-built L1 and L2-class projects, I ended up building a…   Read more»

Got it.Some one sould scoop up the other one.A real value.Thanks Mr. W.

I will take one.

Great rocket. I purchased one of these from John and I am building it now for my L3 bird. If you are working in this direction, IMHO, it is a great choice that can be suitable for L2 and L3…   Read more»

Kari gives me a case of the vapors every time I see her. 😉

Wow that got me all excited again, looking forward to it!Sure was fun to be there in person too!!Got to meet Kari at LDRS!! by slh56ca, on Flickr

Somebody needs to tell these guys about AltusMetrum, or for that matter any reasonably high frequency GPS logger. Has to be a way to certify and doesn’t require someone to stand in front of a flying guillotine.Neat stuff for sure.It…   Read more»
