final clean up of fins. I covered the edges with a veneer of cardstock 1/16" strips to cover up the balsa edges. One lower fin remaining, to show the difference. Will hide a launch lug in one of the air scoops. That Deep Space Transport just looks too heavy and draggy to work as a mini downscale clone, unless the main body tube is min dia for 13mm engine mount maybe. Not sure if I want to try that one and have it end up too heavy to fly on an A10-4T. I guess that's what they make OpenRocket for, when the mind sim is marginal at best and you need a more exact answer.
