Probably not. The instructions should tell you the correct throws, and then you put the pushrods into the holes that give you the right throws. If you are using a computer radio, then you can set it up for max throw, and then limit it via your radio.

As a starting point, I usually go about 3/4 out on the servo horn and 1/2 way on the control surface horn, but set it up for the recommended throws per your plane's manual.

Good luck

You set it up initially for high rates by making "mechanical" adjustments as close as possible. "Mechanical" means moving pushrod connections in/out as needed to get the desired throws. After getting as close as possible this way you can fine tune with the TX End Point Adjustments. Next adjust low rates as instructed in the manual for the radio system.

You can switch between high and low rates at any time but be a little careful until you get used to the way the plane flies in both settings. Have a little altitude before switching. Best to take off and land in low rates usually and also get the feel of a new plane in this setting. When comfortable at low rates get to a safe altitude (50+ feet should be enough) and switch over. Carefully feel out the plane again and ALWAYS remember to give yourself some extra altitude when trying something new.

when you say high rates is that the setting for sharper or quicker response from the sticks and lower rates is a little more slower or not as sharp.......... and when you switch do you switch with one of the toggle switches?

High rates=large surface deflections.
Low rates=less surface deflection

Hi/Lo is controlled by the D/R toggle switches (2). The Aileron D/R switch is on the upper right corner and the Elevator D/R is on the upper left corner. They are labeled Elevator D/R and Aileron D/R.

You need to bury yourself in that manual and read.

You probably would be far better off setting things up for mild control at first, and get used to the way it flys with the minimum amount of throw.. especially considering that this is only your first plane after your trainer (second plane). I even set up my aerobatic planes with minimum throw and keep them that way for at least the first several flights.. to get used to the way it flys and to see how much more deflection I can handle.

Then, you can set up minimum throw as low rate, then dial in small amounts of change for high rates until you are happy with what you have. It just isn't worth it to take a chance on having a plane that has a .5 second roll rate for the first few flights.. you will definitely find that you will be behind the curve all the time and struggling to fly it straight and level.

We had a guy at our club with a Sig Something Extra that he bought from someone after it was built. It had several flights on it by the original owner, but the new owner had never flown it. So, he fueled it up and took off. He never looked at the throws on the ailerons and elevators, which was his second mistake.... his first was attempting to fly this thing after just recently solo'ing on a trainer.

He managed to get it in the air, but it was obvious that he was really struggling with it, not able to do anything with it except trying to correct from a previous maneuver. I asked him if he had trimmed it yet, and he said that he was not even able to fly it, let alone trim it... and asked me if I could take over.. which I did. I flew it a bit and found it to have a roll rate that was beyond belief.. with a very VERY sensitive aileron and elevator setup. It did not have exponential dialed in at all either, which may have helped him.

Anyway, I managed to get it on the ground for him in one piece and we went to work with setting up his plane to make it flyable.. for him at least.

After we did that, he was a very happy camper.. the plane flew just great.. but at a considerably reduced throw in all control surfaces plus a little expo dialed in.

Moral to the story.. for a new flyer, new plane, and a capable plane, use the minimum for a while and get used to flying it that way and slowly add more throw as you see the need/want for more.

CGr.
