I just got a e-mail from Bill Altman, he said he did a geological survey with his T-rex heli yesterday, and he quickly pulled the throttle off, and noticed smoke coming from the heli. He ran over and yanked the battery out and tossed it, and it blew up in mid-air in a fireball.

Good thing it didnt go up in a fireball while still in the heli. Ironic that this happened just a little while after my incident.

I would recommend the following for all you guys.

1. Be aware that in ANY kind of impact with a lipo, it is possible that the casing is ruptured, or that there is a electronic short inside the battery that can, and most likely WILL cause a explosion.

2. Use EXTREME caution around batteries that are puffed up, crushed, smoking, or otherwise damaged as it is very likely that the lipo will burst.

3. If flying where there are flammable materials, it would be highly recommended to have a fire extinguisher available at all times. Turbine pilots do this all the time, so should we.

4. Lipo ruptures can burn at 2000+ degrees, and the fumes are toxic. Use caution.
