If you want details, Initram’s owner, John Wilson has been documenting this conversion from an Atomic 4 on his Blog in great detail… The test run just took place the week ahead of Labor Day, 2010. Once the folding two-blade prop is replaced by a fixed three-blade, John and his father Ian, will be even happier than they are now.
Go here for a wonderful story:
