Hi Guys,

I have finally decided to fly my learjet that i built 10 years ago, i never flew after built it and it got damaged in between the years. When i built it, i modified it extensively also, i added almost all scale features and control surfacs that i could except of extending the fuselage. I have flaps, spoiler/speed brakes, scale ailrons, stall fances, stall strips on the wing, i scaled up the elevators and rudder.
I also installed scale nose gear and 2 bogie main wheels on mail gears with mechanical retracts, I also made working nose and main gear doors but i wont be using those now. With all these features and 5 servos in main wing this jet is going to be on heavy side, not to mention i finished my model in silkspan and automotive paint. When i first completed the model i bought Magnum 65 Gp for it and its been traded since then and now a friend in hobby have 2 OS 50s that he highly talkes about, specially says those engines are power house!. Now my question is that if i could use OS 50 with pipe or w/out pipe on this jet?, would it be enough powerfull for its weight or should i go back to 60sz engine?.....I need serious advice here, dont forget that wing loading of this jet from factory was 29oz sq/in!, but with all this weigth it will be more...And i ahve hears that this jet wants be flied in to land properly....
