Good to know, thanks!
I think my current plan is to use up my two H123W motors and then do some
I/J stuff with my PM Spitfire. PM has some good recommendations for J
motors that will work okay without retrofitting reinforcements into the
airframe. At that point, I think it'd be time for something like the
aforementioned Madcow kits on smaller Js with piston eject and then trying
electronic deployment.
Yeah, I'm not too familiar with the devices used for higher-altitude
recovery. My first exposure to HPR was a school event that brought me to
October Skies 2019 with the club's piston eject 3" flying an I and custom
~6" flying an L. Both had a drogue/main pair of chutes. I saw some of the
equipment used and now know the name Jolly Logic, but I feel like I'll need
to do some more research. :)

Those larger Madcow kits John mentioned can be flown single deploy or with
an optional electronics bay. One approach that works nicely is to build it
with the bay but not actually put any electronics in, just put the main
chute in the bottom and leave the top empty, fly it a couple times, get the
L2 done, and then you have a platform to add electronics at your
convenience.
All that being said if you haven’t flown any I motors yet, you should do
that in your L1 rocket, if only as a confidence builder. It also turns out
that the typical L1 rocket can take a smaller J no problem - I’ve flown
both mine and my wife’s with smaller Js just for fun. The main issue is
getting used to recovery from a higher altitude flight (see: chute release,
and maybe invest in a basic tracker sooner rather than later).

Hrm, yeah. I definitely agree that trying electronic deployment for the
first time on a launch with nerfed performance is a good idea. I'm hesitant
to modify my PM Spitfire for this, though... I think I want to keep it
as-is for now.
My current thinking is to get a somewhat larger kit for L2
experimentation, one that can fly with underpowered motors while I'm
learning the ropes and then move to more fun boomsticks later on. Thanks,
John! I'll definitely look into the DX3 or Frenzy

Hi all,
Hope you're all doing well! Sad to have missed DA this year, but I've
been making the best of being stuck in school 😉. Santa Barbara is pretty
great for watching Vandenberg launches, though!
Anyway, I'm curious if any of you have suggestions for L2 kits intended
for electronic deployment. I plan to use my L1 rocket with a J motor for an
L2 cert sometime soon, but it's piston ejection. As I understand, the next
milestone is to fly L2 with a separate ejection system.
I'm starting to think about why my kit options are... Although I'm sure
it'd be a thoroughly rewarding experience to fiberglass a custom airframe,
I don't think I'll have the time to make it work this summer. Are there any
L2 kits that would allow me to skip that step for now?
Can't wait to finally fly my L1 again sometime this summer!
Thanks,
Neil Balch
