Still on the fat-bastard side of heavy (12-13lbs fully loaded), it really doesnt bother me as I have no one to race but myself... and dogs sometimes...
The Gmaxx arms will indeed work with most towers, but to get the most benefit from the geometry its best to use them with the gmaxx towers- I tried FLM towers and Nova rc low profile towers and it just didnt feel right, or look right either. You should be able to get the arms seperately if you look in the spare parts section on the Gorilla website.
The plan tomorrow is to take my truck down the woods and do some FOFF style driving up steep gravelly and muddy banks, see how this thing handles on something other than grass for a change. We (sister's boyfriend, his friend and myself) will film it hopefully, should be lots of fun.
