Shell was from Banggood.com £4.82 inc postage!!! http://www.banggood.com/HOBIBA-18-2_4G-Brushless-Off-Road-Car-Canopy-VR-08001-A-p-972591.html main difference is the side rails need work as shell is slimmer than the 7 TQ original, front need slight trimming around shock tower. Is there any slimmer rails that fit the 7 as I heated and formed the original ones to fit. I am using a Turnigy TGY-615BL Brushless servo 12Kg /0.08sec is anyone else using one of these (very good speed and centering) .
