Thanks for the replies! I had read somewhere that the DX3 was a good L1 rocket. Without engines, its 44 oz, 1250g. I had planned to build it and test it myself with sub 80 "G" engines. Hadn't even considered the 1500g limit. There are two versions, one with an ebay and one without. But the kits are both a about 1250g mass. The smallest 38mm engine, loaded, will likely weigh more than half a pound (220g)* which may put me over 1500g. So my understanding is that I can build it, and can use it with an H engine in the presense of 2 certifiers to gain the L1. After which I can fly it with any engine up to "I". For safety reasons, I will want to run the thing with a G before I use an H. So before I certify I have to find a large area (no probs - I live near many farms some of which are 600 acres) and have someone with an L1 present if I want to test it with a G engine. This may cost me a lunch!
I'm kind of surprised that there's nothing closer to philly. Maybe a function of needing a large area without many trees?
*Does anybody know of a table for specifications of (for example) aerotech or Cesaroni engines? The Aerotech website doesn't list masses for (for example) the RMS-38 reusable engine. Thx,
