It should fit a Mongoose, yes.

On B6-6....I will have to see what a Quest B6-4 does first. I expect that an Estes B6-6 will be too long a delay. But it's worth a thought.

Considering the thing weighs a little over two ounces without a motor (2.16 ounces in this particular case) it went a little higher on all three motor types I tried than I initially expected. There is something to be said for those nice thin fins.
