Also the car is VERY light! I built it with only a few option parts and only 1 of them being lighter weight which was the Ti Turnbuckles and weighed in at 1498 and that's with 25 grams under the battery, it is the Reedy 3900 low profile battery though. So if you add just the AE Ti screw kit & light weight body you will easily be able to run a full sized battery and the brass C mount and still be under weight.
