you could try this
1. revers c-130 right to the far end of carrier till your tires are just about to go over the edge
2.flaps set to 30
3.throttle up to full power then release brakes push down on stick until last minute then just let it go after c-130 leaves the deck give a little pull on the stick just enough to get nose up and not to lose to much speed

i did this 5 times and i got it airborn 3 times
