More of a philosophical question than one of physics. You could easily exceed 20,000 feet with a long-burn K and a 54mm MD rocket. I personally didn't/wouldn't do that for a cert flight, but YMMV.What's the highest altitude you've heard of for a Level 2 Certification Flight?
Nooooo this thing is gone??My L2 went about 3800ft (OpenRock Sim) with my Warlock on a K535W DMS, was super awesome until the chute release didnt release

Shew! That's an awesome rocket, glad it made it through alright.Actually the damage isnt too bad, fell pretty horizontal and didnt even pop a fin, i had fiberglassed the airframe so just needs some minor patching and paint touch up, she will fly again
I'm working on a L2050 Min diameter project that should be going to Xprs in 2021. Im simming about 51k. Though I'm debating on going with the M1378, even though it is an L3,aerodynamic stresses are smaller, and more altitude.To answer the thread title:
My L2 flight specs are in my sig, 4000'. 4" madcow super DX3 "lead sled". I used a 38mm Loki J320 red motor. I have a build thread that lays out the project.

As for the original post:
I bought the MC 54mm MD Tomach a while back and someone used that for there L2 on a CTI 6xl L motor to 24,000'.
As for max altitude for a L2 motor, that would be a 54mm MD carbon fiber bird on the Loki 54mm L2050 white motor with tailcone. I have a sim file for this setup in OR to 42,000' and plan to make a run at the Tripoli L altitude record with that motor in 2022. I will be flying the smaller 54mm Loki L1040 red motor next year to 28,000'-30,000' to test my ability.

My first attempt at level 2 hit 7,000 feet in about 2 seconds. If ya gonna push it...Hit the button!

Do you mean 20 seconds? If you got to 7,000' in two seconds, you would be coasting for a really long time afterwards...My first attempt at level 2 hit 7,000 feet in about 2 seconds. If ya gonna push it...Hit the button!

After 2 seconds it was gone so other than a sim... I have absoultley no clue. it just went very very very fast. ODo you mean 20 seconds? If you got to 7,000' in two seconds, you would be coasting for a really long time afterwards...
Not to mention that’s over Mach 3Do you mean 20 seconds? If you got to 7,000' in two seconds, you would be coasting for a really long time afterwards...
I managed to set an N record on my L3 cert flight back in 2006 (34K). That record didn't hold up for long, but to the best of my knowledge, it was the highest certification flight for about a decade until it got smashed in 2017 (a flight to 64K). Anyone wanting to set an L3 certification altitude record is going to really have to work for it.I've heard a few times of people wanting to set a record on their L3, but can't say I know of any set on an L2 flight.
