    Best choice of motor for L1 on a LOC IV?

    Hello everyone, Just ordered a LOC IV and will be attempting a Level 1 flight next month in Lucerne Lake! I want to fly it on an H motor and want to go with the safest and single-use option for this flight. I was thinking Aerotech H100W-14A but not sure if it would handle it well. Especially...

    Aerotech mid power thrust ring

    I recently bought the Aerotech Cheetah and do not want to use the engine hook. Instead, I am using an Estes motor retainer. The Aerotech instructions say to slide the thrust ring till it hits the motor hook’s end. Can I get rid of the thrust ring or do I need to use the motor retainer?

    Recommendations to fix aerotech G force

    My Aerotech G force took a nose dive today due to my fault. I hadn’t flown it in 5 years and forgot it came with a heat dissipating metal sponge and baffle. I loaded dog barf and sent it on it’s merry way with a G74. It went up beautifully but didn’t have enough force to pop open and ate it big...

    38/1320 hardware usage

    There is only one Aerotech reload for the for 38/1320 hardware, the J510. Everyone who has reported, praises the motor. But how many J510s do you burn? Or do you use adapters for 38/1080 and 38/720 reloads to expand the usefulness of the hardware? Or did you buy the case just so you had a full...
