To pearl 414

Im glad to hear that you will keep working on this plane as they are wonderful to fly. If you not keen on a bigger saito .72 then maybe the .61 or .56. If not saito then an OS .56 alpha or .70 ultimate.

I would try without the perry pump first and see how you go. Mine does not have the pump and it runs fine. A littie hint though when you are starting the engine leave the glow starter on for 5 to 6 seconds before turning the engine over. I find it starts easier that way. If all else fails install the perry pump.

I find that prop selection is critical and i spend a fair amount of time on this while setting the plane up. Sometimes i get it right the first time and other times i may change the prop 2 or 3 times till i feel comfortable with how it flies. Along with prop selection setting the travel rates on the control surfaces is critical. The travel rate on mine is set at 85% of the total servo travel with dual rate being 125% of this travel rate. Still have another 15% i can open up the travel on but this is enough at the moment.
