yea a 15 minute main will require a large pack, but if you switched to a higher volatge setup such as 5o 6s on a 1409 you might be able to take a sub 7 pound car and squeek 15mins at race pace on a 340 (+/- 10) gram lipo, I run a 420 gram lipo in my 808 and joshs mp9 and both make 15mins and are both way over powered.
My ideas if you wanted to meet your target wegiht You can shorten you battery leads by flipping your lipo around with the wires to the rear. You can use lighter tires and wheel setup (buggy holeshots will bring the rtr weight down on the scale). you can do a little drilling and milling on the battery tray. you could loose the rx box and run the rx on the chassis right there. You could use the stock shock towers as templates and cut your own carbonfiber towers. you could go further with a carbon top plate.
It doesnt take long to get 150gr + the 150 from a differnt lipo might even save weight buy changing to a 1409.... just some thoughts...
