The PML Explorer is a good rocket for a Level 1 project.
What's a Good Level
There are plenty of good choices from a variety of manufacturers. My
recommendation is the much overlooked PML
Explorer, with a 29mm or 38mm motormount. For some baffling reason,
experienced rocketeers forget the "keep it simple" rule and
suggest the PML Small Endeavor
instead. The Small Endeavor's split fin design essentially makes it
a six fin rocket, which is twice the work. The forward fins' internal
fillets and aligning the split fins are an unnecessary challenge for
the novice. The Small Endeavor has absolutely no advantage over the
Explorer and twice the liabilities.
My second choice is the PML Patriot
with the 38mm motormount. It's 4 inch diameter airframe gives the
novice plenty of room to work with. It's really easy to stick a
plastic spoon filled with epoxy inside the fin area to create the
PML's KwikSwitch motormount adapter is great, innovative concept.
However, I would recommend that novices avoid it on their first
project. Again, if you are new to high power rocketry, keep it simple.
