Shorty Packs a way to reduce weight

As it is My Alcyon II weighs in about 1490g with a PT and IP saddle packs. The IP Saddle packs weigh at 280g. The turnigy saddle packs weigh at 260g. I just discovered shorty packs which are 97mm long, 47mm wide and 25mm high. that means they are the same dimensions as one saddle pack except they are longer They also weigh at 200g only. Last night i did a mock up shorty pack placement on the car and checked the balance. It was enlightening, i still get good 50-50 LR balance, and the FR balance is only biased towards the rear by 31g. And the cars running weight is brought down to 1383g  even with PT at the front ! That is amazing ! The less Mah on the batts shouldnt affect performance much, but the weight decrease should help the car use up less tires and also use less turbo. I am in the process of negotiating a 3 shorty pack lipo deal and if it goes through, i will have them to test on my kawada. i will probably have to use much softer springs to compensate for the weight loss. I can actaully place some weights at the front bumper to bring the car up to legal wight of 1400g and laso bring the weight bias FR to perfectly 50-50 !
