Mine with full electrics installed with no weight at all added came in at 1526g with a full size servo... I know the 2wd weight limit under BRCA rules is 1474 and so I'm happy to leave it at that... I ran it at Coventry astro track on Sunday with no weight added and for its first outing I was more than pleased with the performance - My final time would have been good for a B or a C final within the 4wd's
