Sorry didn't mean to offend you. :disappoin

Lets look at what is happening when you take off.

If you juice the throttle then a whole bunch of things are going to happen all at ounce. Torque, P-Factor, the blast of the prop wind hitting the left side of the rudder ( this side of the pond) and several other things happen very quickly. Normally, the plane will want to turn left so you give it right rudder. It's natural to correct this and more than likely it will be over corrected and now the plane is heading to the right very fast. Most people panic and over correct with left and then your really getting into a bad situation. Next up elevator is attempted just to get the plane in the air and again probably over controlled. Now your more than likely flying very slow approaching a stall ( loss of heading elevator control going south and ailerons loosing effectiveness. BAD!

Try this:

First make sure the plane will roll straight down the runway. Next make sure that your steering will only allow you to turn in about a fifteen foot circle if smaller you have to much control on the nose wheel and you should adjust it.

OK, Taking off easy right!

Taxi out to the center of the runway and if possible stand behind the model ( slow day at the field or early before the troops show up) with the model on the center line add power until it starts to move. Right away you will see what direction the model is going to pull - left or right. Correct to stay on the center line holding the rudder input and gradually add full power. You should be able to see the model kind of bounce along the ground and that is when you add only enough elevator to raise the nose. I like to point the nose at the horizon or a landmark like a small hill to climb out. Continue using the rudder to maintain heading toward the point you have picked out as your takeoff reference.

You shouldn't have to make more than 2 corrections and if you have to make more then cut the throttle taxi back and start over again.

You can really impress your fellow club members with a natural takeoff such as this.

Above all play it safe and have fun.
