are you doing any Large MR or HPR? level 1 or what?
biggest I've flown is a G motor,about 2.5lbs of rocket,all scratch-built.
(I'm not certified)
I'm not certified either. I have only slightly more than zero money. I'm
flying my fleet of re-built rockets until they're broken beyond repair* or
lost. Only occasionally do I spring for a pack of black powder motors:
mostly I fly with a saved-up selection of 24 and 29mm RMS reloads.
Additionally, there is really no location we can fly anything very big in
easy driving distance (central Oklahoma). Some folks drive about 100 miles
to Sayre,OK to fly "big" stuff. People *have* flown G/H/I (and bigger)
stuff on local fields, but it's really a bad idea.
Quote: is R.M.R still flooded with spam?
Not right now. The little boy pumping out the sporgeries has decided to
give it a break (or got filtered/shut down by his ISP). There is a lot of
nonsense bickering and name calling though.
* One of my biggest rockets is called "Fat Bastard". It started out as an
Estes "Fat Boy". That crashed, and was rebuilt using plywood centering
rings. *That* crashed and was rebuilt using ply centering rings punched
out to 24mm and ply fins. THAT crashed and was rebuilt using a full-length
24" BT-60 body tube and a 24" "payload" section and fiberglass re-enforcing
around aft end of body tube. The next crash/rebuild should be
iinteresting...hmmm...carbon fiber? |
