Old G80-4s not good...

[stardust]

A heads up!!!...the old type AT G80-4s. Out of three I used, 2 of them exploded the tail cones of my V2s. I have let NAR know. Joe Hinton with Giant Leap facilitated an exchange of all 20 of the remaining motors I had with Aerotech. Giant Leap is great. Yes, plastic molded case type.

Friends, don't let friends, fly with G80-4 motors!

Are these the plastic molded case model? Those have been known to have problems. The older old G80s were fine, the molded case 100Ns model was bad, and the new 137Ns model is fine.

Are we talking about Blue Thunders?

Correct. The forward closures of the AT 100 Ns G80s had a tendency to leak (melt) shortly after ignition. I cleaned out the guts of a Mirage that way.
