So I tried my bungee system without success today.

The model rose about 1/2 a metre before cartwheeling in (can't see any major damage yet).

I measured the bungee tension as 13kg - twice the model weight.

This didn't seem anywhere near enough to get the glider up to launch speed.

Does anyone have any suggestions for a bungee tension / model weight ratio!

Thanks,

Phill

Nice!

What tension do you have on the bungee?

Thanks,
