After watching u tube I chose the Loc 4 to be my level 1cert.rocket.
The LOC-IV flew beautifully with an Aerotech H219T for my L1 cert. Needs minimal ballast to ensure good stability on H and I motors which makes this a very easy kit to build and fly. Something that should be mentioned is that the fins in my kit were smaller than the provided simulation had, so make sure to double check.
Easy and run to build! I put mine up on an Aerotech H100W for my L1 cert flight with no issues. The large apogee deployed parachute put it down really slowly, so make sure you aim into the wind or have a big field.
This 8s an amazing rocket that I fly on G motors regularly. I love this thing. I modified it for electronic apogee ejection. Great solid go to rocket that everybody should have at least 1 of.
