There are bargains to be had at Heli-Expo ‘13, especially for operators of pre-owned or early model helicopters. “L.J. Walch is excited to be able to offer owners of Sikorsky S61 helicopters brand-new motor generators, manufactured fresh by Ontic Engineering and Manufacturing at a healthy discount,” said Bill Luty, manager for sales/special projects for L.J. Walch (Booth No. 3426).
