Which L1 bird will fly best on G engines?

The LOC EZI-65 flies well on a G80 with short delay (4 sec).  My brother went
on to certify L1 on his- the H180 -6 is a little short unless you are going
into the wind, the H180 a tad long, but it is an excellent rocket..

Have you considered the Binder Design Thug?  It's in the ballpark for
the diameter you're seeking, builds nice and strong, and gives a great
performance on a G64 or G80.  On an H128 it's a decent certification
bird...meaning that you can still see the whole flight.  Mine comes in
at exactly 32 oz, without the motor or recovery wadding (and *with* a
few ounces of noseweight).

As a point of reference, 5 members of our NAR Section built and
certified on Thugs early last year...5 launches, 5 certs, and lots of
really nice flights since then.

I don't know if it's still available with the 38mm motor mount option,
but the thing should be a screamer on an H242.  Even the H238 (29mm)
should kick it pretty good!

Gary,

Go to  http://webhome.idirect.com/~andrewi/Evolution.htm and check out the ARG
EV-3. It's 4"x46.75" and I figure it weighs about 30 oz. finished. I got mine
at ARG (in person) and I had Andy do a 38mm motor mount and cut the TTW fins as
such.

He's got one in the shop (the same one shown on their web page, too) he says
he's flown about 20 times.

BTW, the prices are in Canadian dollars; $99.95 Cdn is about $65 US. Nice kits,
worth the money. Moreover, nice guys, deserve the business...

One more point on the Thug -- if you add a third centering ring, you can
build the entire model with yellow glue and it'll stand up to any 29 mm
motor made; mine has had two fins sheared off longitudinally, with both
failing in the plywood outboard of the fillet; it's also lawn darted
hard enough to irrecoverably embed the nose cone in the ground, without
any sign of damage to the motor mount or fin can.  I cut off the tube,
installed a coupler, grafted on a fresh length of tube, and installed a
new nose cone -- total time, about an hour plus glue drying, and my Thug
was ready to rock and roll again!

These birds are hell for stout -- but be prepared to calculate CP and
add nose weight to maintain stability margin; mine needed about 90 g of
lead in the nose to be stable with an H128 (and no epoxy in the tail,
though it does have my UMRS).

Oh, and they only go about 400 m on an H128-M, so your cert flight is
easy to see...  B)

I L2 certified with a THOY Falcon. It would certainly fly on an H, but for a
G I'd leave out the payload section. Same deal for the EZI-65 or any other
similar rocket.

My first choice for an L1 rocket is still the LOC IV.

Which to fit into the given format would be:

LOC IV                                47.5", 29 oz

I used an NCR Phantom 4000, stealing all Kaplows good ideas for modifing
the LOC IV and applying them to the Phantom. At the time of certification
it was about 28oz empty, 50.5" and flew nicely on F62-4's as well as H128-S's.
It's now about 39oz, 60" and should still fly on F62-4's to about 500ft or
about 1000ft on the H128.

Get a JB Javelin. It's what I used for L1 (with an H124-10). Flies great
on F40's, F52's, G64's, G33's, G35's, H124's, H180's, etc...

I would go with a Loc Vulcanite.  I just ordered mine and it is light enough
that you can ever glass it and launch it on G's.  Then after L1 on an H128,
you can make it an altitude rocket and fly it to 4000 feet on an large I.
If you don't want to launch on G's, I would DEFINATELY recommend a Public
Enemy psycho.  Looks awesome.  I have mine and it is waiting for a motor

Thanks Kevin
