I have got a few standard engine based rockets in the last year that have a thin walled blue paper tube for the motor mount.
This tube is the most useless POS parts in the entire history of useless POS parts. Each time I have flown a rocket with this blue tube mount, after the second or third flight, the motor and hook begins to travel about a half inch. Of the three I have had this problem on, two of them have big rips in them...no doubt caused by the kick of the ejection charge pushing the motor down against the hook....the third one was scorched badly just below the thrust block and burnt through giving a large hole for the end of the hook to slide through.
I now have a box with about 10 Semroc BT-20J tubes in it just in case I get a kit with this crappy blue motor tube.
Granted, Estes customer service rules all and has replaced the rocket on all three occasions....but why even include such a craptastic part in the first place?
Anyone else had problems with this crappy blue tubed motor mount?
