With the introduction of the Skyripper 29mm motors, I suspect it would be possible to put together a hybrid powered rocket weighing much less than 3.3 lbs.
Am I correct in assuming, however, that such rockets cannot be launched under the LMR notification rules? Either the 125g fuel thing or the "not a model rocket motor" issue would shoot it down? (I don't see the fuel weight info on Skyripper's page, but note that their 29/125 engine carries 125cc of oxidizer alone)
LOL-- do the rules ever change to keep up with the technology? (i.e. the125g fuel restriction is aimed at APCP and other composite fuels)
TIA for any thoughts.
