Granted, it will take a number of H & I flights before they get a real feel for the power of those motors, if they have confidence in their build, I would say go for it.
However, I would think this is a GREAT motor if you want to "certify with style", are used to hot/top impulse motors (if your biggest motor so far is a G64, you may not be ready)...
I'm just throwing it out there to provide the best chance for a successful L1.
Can a new driver get the first gen Viper when it first came out and drive it home fine?
Yeah... about 60% succeeded.
I've seen a few "don't blink" cert flights and usually the general feeling seems to be "why?" or "that's nuts ". I usually don't hear the results (took too long to find? Broken? Lost?).
Still, if you're up to the challenge and really want to, go for it. I'll still wish you luck and help any way I can.
I'm one who loves challenges and probably have one of the crazier L2 certs attempted (and suceeded), but I also realize that's not for everyone.
For me, L1 cert is best to do whatever is the greatest chance of success since for many, this is the doorway to real HP and this was my route (Sumo on some milder H on a whim).
However, if one falls on their face or the door slams on them and they lose their rocket, they may not be up to do it again. Idk, but I've heard of this before all too often for different cert attempts.
Just my opinion and it's really because I love this hobby and want others to succeed into HP.
At our club's last launch this season two fliers tried to cert before the rain shut us down. One was a LOC Goblin and the other had a custom 4FNC I think. They both chose mild H motors and both succeeded and were super happy. I got videos of both (no need to not blink lol) and it made their day and made my day. I wish this for others too.
(EDIT: Tried to post the two cert flight videos, but no dice. Goblin I added the "We are the Champions" song and the other had the Mission Impossible theme.
