Yeah, but you build your rockets WAY tuffer than I build mine. And if you
would pop the main lower, you wouldn't get so much drift, either!!!!!:-)
Seriously, though.....I use an R-14 on most of my bigger rocket flights, too.
The R-18 that I have is one of the old X form types.... one of the ones Ray
used on his Aries. I used it on my 80 pounder and, while it worked just fine,
the rocket did land hard. I've found it to be quite nice for a 30 to 40
When I made my recommendation, I was assuming a fairly stock build, on the
Bruiser EXP, which includes the fins NOT going thru to the motor tube. If the
fins DO go thru to the motor tube, he could probably land it on an R- 9 with
little problems. I've seen LOC's 7.5 inchers pop a fin off real easily, if
built stock. I've also seen stock ones land just fine, even using the stock
It all depends on two things (three if you count luck). The wind and the
hardness of the ground. If a stock built rocket hooks a fin, it will (probably)
pop right off. If it lands too fast, the bottem of the rocket will (again,
probably) be damaged. On the soft ground, in Geneseo landing hard isn't a
problem. Digging a fin in, is. On ground like Kansas (where the HUGE furrows
dry to a granite like hardness) landing too hard would be more of a problem. Of
course, than there's the wind. While using a bigger chute will bring the rocket
in softer, it will drift MUCH farther. Also (again in places like Kansas) the
high wind will drag a rocket with a big chute along the ground or thru those
afore mentioned furrows and shred it worse than almost any normal landing
In short, I change chute sizes to try to minamize what I precive to be the
biggest problem. Some times (most, actually) I need to get the rocket down with
as little drift as possible. This means coming in fast and landing hard. On all
my newer ones, I haven't had any landing damage either, but I build the back
end strong (read heavy:-). After poping a few of my own fins, I decided this
would be the best compremise.
By the way.....are you planning on doing Kansas again? It looks like a bunch
of us are.
And, since we haven't any "serious" controversies on RMR lately :-) Why don't
we discuss the merrits of using chute bags as opposed to blankets! Than we
could segway into a discussion on the "proper" way to fold a chute, and weather
or not to wrap shroud lines around the chute. Should make for a real lively
discussion:-). Talk to you soon.
