sheesh man, Glad you are ok!
Maybe it's a good thing Las Vegas is nothing but a huge desert or we might have got to see you on the evening news. "Exploding lipo battery falls from model plane and burns down half the state...." What with these severe draught and fire conditions all over.?
Just good that you and plane survived to fly another day. Also, helping to keep you LHS in business.

It would be interesting to know the details that lead up to your Lipo failure.

What Mah was the pack? What was the amp draw of the power system? Was the pack damaged in a previous flight/incident?

If you read the threads on Lipo fires, most of the time it can be attributed to some kind of user error or oversight.

The 'Wattage' (Kolkam) 1500 is 7C dis = 10.5A discharge.

I have several different sizes of the Wattage packs, including the 1500 and they all have delivered within the rated "C" for me.

The "C" of the new 'Impulse' packs is quite impressive. Only time will tell if they deliver as rated.
