I recently bought the AM5 to get me to visit remote sites for imaging. I went with the TC40 as its has been purposely designed and built for supporting the AM3/AM5 for such a reason. I can report that it supports an Esprit 120 and accessories weighting in at 14.5Kgs easily. Just remember to or accommodate for possible balance issues when using a large weighted telescope east and west of the pier or mount head. Safety first as you don't want to damage or lose a prized telescope. So, weight the mount down using a suitable weight in the accessory tray. Fantastic support and delivery from FLO as is to be expected.
