I ordered a remote package from dklm so I will wait until it gets here to sort out the Clark board. If it works out I may give those another shot. I will withhold final judgment on the IBU system until the replacement board gets here as I still need a smaller footprint system for my enigma. At the moment I cannot in good faith recommend them. I appreciate additional options for the hobby but not at the expense of reliability and ease of installation. Tamiya is the gold standard for a reason.
