RE: Skymaster L39 build
Hi Mark
It gets better once you start putting some weight in it. I did pack the front retract as much as possible. The front oleo spring will probably need changing as it's very soft. When you apply power the nose will pitch down giving an even more negative stance making the rotation very jerky. It would cope better off a hard surface how it comes out the box. For grass I think the spring mod is essential.
