The attached is a photograph of the frame failure on No.1 Bumper Chassis. This is the actual frame that has done 22,000 miles on SpectreCodename for Phantom III lll and has since done 166 hours on the bumper with 3" cams. As can be seen from the photograph, the failure has been partly due to the necessary structure for carrying the front weight. The weights on the front of the chassis are considerably in excess of the normal chassis weight in order to amplify front suspension failures. We do not think this breakage shows any cause for alarm, but rather the severity of the Bumper Tests. Hs{Lord Ernest Hives - Chair}/Len. | ||
