Magnum .40 questions

Bought a used Magnum .40 on ebay. No instructions. Questions:
1. What would be a good prop to use, mabye a 10X6?
2. Max RPM?
3. How to start. How many turns should needle valve be opened?
Thanks in advance!

Propeller Size Recommendations XLS 40 Engine 8.5 x 6 9 x 6 9 x 7 10 x 5 - use for break-in 10 x 6 10 x 7 11 x 5 11 x 6
Ideally you want a propeller that the engine will turn in the 13,000 - 16,500 R.P.M. range on the ground, yet power the airplane sufficiently.
Starting point for high and low needles is 2.5 turns from closed

Which model is it? Ball bearing or not?
