I've got a sig hog bipe comming. On several posts there has been mention of runnning full lengths stringers to take the square shape out of the fuselage, makeing it more rounded. How is this down? Small formers on the sides, sheeted and blended or what? Want to pu a round cowl on the front and don't want it looking out of place or stuck on. Also, seveeral places make cowls such as Stan's fiberglass etc. Which one to order for a round cowl to enclose a Saito 100? Thanks for the help, Tom.
