I am finishing to assemble a GP Pitts, following the recommendations of GP, I bought one US 41cc, however this is my first gasoline engine and I don't know how to installing it, someone would be able to indicate me where can I find information on how to install it

http://www.greatplanes.com/manuals/gpma1218-manual.pdf

Look at pages 24 and 25.

I have the engine installed in the airplane, however I do not know how to connect the ignition killer switch and how the hoses of gasoline are connected and where should be installed the servo that controls the engine.

Do you have a friend with experience with these larger engines? if so, get help now! if not........go to the Great Planes website and read the "tech warning" on gas engines and cabane strut BEFORE flying this plane. Several factors will come into play for your success. While balancing your prop be sure to dull it down, sharp edges!......this size engine will cut off more than a finger!
You'll need a tachometer to check engine rpm while running in the engine prior to flight. Simply "thinking" it is pushing enough wind will not work with these larger engines and heavier planes. My main concern when anyone moves into larger planes is the torque these large props/engines produce. Dogging the small planes around is easy........do it with a gasser and someone could be wearing it! example: coming in for a landing approach at low idle and decide to go around for a better line-up on the runway. the plane is at a low airspeed and low throttle then the pilot suddenly sticks full throttle! the plane WILL torque out of control and someone could get killed. also, how practiced are you at using the rudder? it is a major part of flying big birds safely. have fun and be safe!

i have a gp pitts too i also buoght a us 41 but heard i flys it ok if
fly it scale like. but i am looking for a little more "umph" i'm considering a fuji bt-50sa or zdz-50. pricie motors but i think one of these will give it the performance this plane is capable of.

fishbone,

i had my pitts for 2 months before i decided which engine to install. finally, i decided on the BME 50 and believe me, this engine has the more than enough power.......awesome vertical and will hang at half throttle or just a tick or two above half. if you have not purchased another engine, maybe you could check into the BME.

hope i was some help
