Motor Liner burn thru

rabbitcreekrockets · Apr 8, 2014

While taking apart my first G motor after flying it for the first time I discovered what looked like a burn thru in the insulating liner. Is this a common thing? Did I do something wrong.

It was a G64-7W using the RMS29/40-120. Second flight of the day after a successful flight on a F40-7W. Flying an Aerotech Initiator(bonus rocket pick included).

Yup, it happens. No more pictures with snow please, we finally get a few months without it!

Thanks, just wanted to be sure I was going down the right path. That is the river that goes through town, the ice won't break for another 3 weeks or so. It is a nice field to launch from though.

Groovy. Whereabouts?

Try greasing your liner.

Nothing to worry about, it is just the liner doing its job. Mojave greens run hotter then other formulas and almost always burn thru the liner for me.
