screw it flt 2 CATO 10272018.pf2 Description
This was a sad day. Launch was perfect & then at 2000 feet - BAM! CATO. Everyone loved it except me haha. Happened so fast, these pics only show the rocket in flight & then debris & recovery. Fin can trashed. It was a AT M1780 motor. I will rebuild it some day.
Another observation I made was that the main was deployed at really high speed & it was completely undamaged. Rocketman makes a killer parachute!
Have contacted AT for warranty info. Hopefully I get new motor & case soon!
By the way, this field is AWESOME, way bigger than GRITS. Nobody lost a rocket or put one in the trees & the wind was really blowing, 15 MPH on the ground & 40 MPH at 10,000 feet!

The AV bay, payload, motor retainer, all recovery & about 12" of booster (fin can survived). The fins, MMT, centering rings all shattered,

This is all that survived the fin can.

Oh man, that sucks! Any idea what caused the motor to cato?
Think it just over pressurized from grains collapsing at forward section. At least that's what the experts on site told me.

Were your grains bonded? I think the M1780 is one that AT advised to bond.
