 Setting up your plane to fly correctly....

(not necessarily for trainers)

#1- build and balance, not forgetting laterally.

#2- set up all control surfaces as mechanically neutral or equal as possible.

#3- take the plane up high and then point it down without throttle. If set up correctly the plane should come straight down. Considering the counter balance on the elevator and rudder,
your chances of getting them even are very good, so we move on to the ailerons. If when coming down the plane favors the canopy or looks like it is going to pull out, the ailerons are too
low in comparison to the incidence of the wing. Raise the aileron attitude. If on the way down it goes to the wheels, the ailerons are too high. You must make equal adjustments up or
down on both sides until the plane comes straight down. Doing so a little at a time.

#4- fly the plane inverted and upright to determine the proper CG. When done correctly it should fly hands free in either attitude. This is not to determine the CG for 3D or anything else.
Its the true CG of the plane relevant to your set up and weight distribution.

#5- now that the plane is set up as neutral as possible, from straight and level, add full power into an up line without any other control input. With the top of the plane facing you, watch
where it goes. The rest is simple, but time consuming, as it is trial and error. If the plane goes to the left you need right thrust and vice versa. Once sorted out, pull another up line, this
time looking at the side of the plane, if it favors the wheels or falls forward in a climb, you need up thrust and again, vice versa if it pulls to the canopy.

#6- with all this done, you should be able to go from level flight, at the slower end of cruising speed to full throttle without the plane pulling up, down, left or right. 
Very time consuming, yet completely rewarding if done right. You will see the difference in a plane of any type that is set up properly.

Find the CG of a Model plane

Getting the correct CG setup for your model is very important. Usually you can use the directions supplied by the manufacturer but if you don't know
them you can still set up your plane. Click the link below for some helpful tips.
