Received a replacement tri-gear mount L02-12 today.
Started fitting it to the motor mount. The bolt spacing into the mount is correct, but there was interference into the triagular portion of the motor mount. I needed to do a lot of cutting and grinding to get the parts together. I still need to drill and bolt the triangular portion of the mount.
Trial fitted the components to the fuselage. Some more messaging will be required to get everything fitted close enough to be bolted up.
