Well the thing is, Yes its a Phoenix Strega .This plane is used, I got it off of Craigs. I want to upgrade to a four cycle but since there is a OS40 on it I just want to get it up there. I will definately go with a bigger engine soon.
My biggest concern is landing because it will be a lot faster than what I am used to but Im sure I can manage that too. It came with a 11x6 and 11x10 props. So I was planning to use 11X6 first. RX battery is 4.8 volts I dont remember the Mah, its powering 5, 3001 Futaba Servos and a Chinese Micro receiver its on fm 72mhz and 250cc fuel tank.

How much flight time should I expect on full throttle or what is safe? 4 mins maybe? and what is the range on fm 72? My 2.4 system is hooked up to my foam plane and I dont want to remove it from that one because I have only one 2.4G receiver.

If you guys say I must use 2.4 G then of course I will. I really dont feel like crashing this one. Thanks for the advise I will look up for OS40La reviews and Phoenix Strega reviews so I can get a better idea of what I am dealing with.
