Melf, I have had a spar break due to extra wing loading of a nicad pack of 8.9oz.

There was also 2 bolts in joining point but it fractured at the end of the wing, also there was a small nick in the solite I had noticed previously, and after was a large tear, it may have been extra loading as well.

I don't think this was from the impact as the half wing seperated 100ft in the air and just floated down.

I've never had a problem with the wing using kan and he cells doing high speed snap rolls ect.

On the next build I might extend the leading edge through the fuse and pin it and also use a thicker ply spar joiner.

But as I mentioned before I've never had a problem with other battery's and as standard It's very strong.
