Something is seriously wrong if a G62 can't take a 17 lb plane up unlimited. Must be using a pusher prop. I would never buy a gas engine if that were the case. An OS 160FX can take a 14 lb plane straight up. There are many folks with 20+ lb Stingers on 62's that are unlimited.
In this ARF dominated time, I can understand but won't accept someone buying a heavier engine just because the plane needs nose weight. Folks just need to learn to build. All the posts said the Lanier Cap kit comes out tail heavy so I modified it. Now it will probably balance with a DA 50. Would be nice but I'll use the G62 I have and put the radio gear in the tail. Hope it will hover my 16 lb plane.
