When the plane needs to be trimmed, at what speed should it be done. Does half throttle cover full throttle or do I end up trimming the entire flight.

Thanks
Greg

I fly mostly at half throttle so my planes are trimmed for half throttle. When I do go faster the plane goes up so I just correct it with the sticks. It just depends on how you fly.

I always start trimming a speed the average speed the plane is stable at... not to fast not to slow. Slow enouph that I can remove my thumbs to set trim without worrying about the plane.

once the plane can fly straight and level hands off then it's a matter of a click here and a click there to fine tune the elevator at the speed I like flying at.

If I have to hold the elevator stick to adjust for speed I would much rather input up elevator instead of down to compensate for throttle adjustments.

the speed i trim at depends on what speeds i generally fly that model at, for most its done at full throttle.

Hi

If the trim change is out a lot with different throttle settings you could mix a little elevator with the throttle , starting at a very low percentage and gradually increase until its always in trim, genrally it will be near enouph on all throttle settings to easily compensate.

No matter what speed you trim the plane at it's going to change when you change speed. That's just the way planes fly. If you trim at half throttle for level flight then when you increase the speed you are going to have more air flowing over the wing producing more lift, so the plane is going to climb. And just the opposite is true when you decrease speed. It's part of being a pilot, you adjust. Trying to compensate with mixes or other solutions is just a crutch to rely on. Most pilots either adjust with elevator, or simply change their trim settings for different speeds. A pilot should be constantly adjusting the plane during a flight anyway as conditions change. For most planes out there the mere fact of the fuel level lowering in the tank will cause the trim to change on a plane. If most planes are balanced properly then they will be nose heavy at take off (because you balanced it with an empty tank), if you trim the plane out with the tank full then as the tank drains the plane will start to become more balanced and the trim will no longer hold level flight.

Trim for the speed you are flying at right then. When you add or remove power your elev trim will change. When you climb or dive your speed will change and so will your trim. These last 2 are brief changes and not worth changing trim over. Any temporary change, just use the stick and don't worry about the trim too much. When you prepare to land, you may want to retrim if there is a significant change needed otherwise, just fly.

I was told to trim at full speed that way when you fly at a lower speed you just add in up el. with the sticks, we as RC'er are more ok with using up el. as to down el.

That's true for elevator, but if you're pulling a roll at low speed you could be rolling rapidly at high speed.

When you maiden a model try a very short hop first. Correct aileron if it tracks straight but rolls on lift-off. Correct rudder if it taxis straight but then veers sharply and rolls when the wheels break away from earth. Once you have that trimmed, work on the elevator in flight.
