I'm afraid this will become a bit of a heated conversation and you will need to weed through the responses. That being said, I will venture my take on this.

Being a Stick I have noticed that many variations don't have any right thrust. During your take off run there are forces that will pull the airplane to the left. 2-3 degrees of right thrust will greatly help this situation.

Most guys set their rudder throw in such a manner that allows them to taxi with a reasonably small turn radius. If a dual rate and/or expo is not used that throw is too sensitive for nice takeoffs. The pilot tends to over control and ground loops the airplane.

You mention that it is a 30cc sized Stick so I will assume a 30cc size gas engine eith a Walbro carb. The issue with a Walbro is the throttle curve is very non linear. The typical setup has the power coming on quite suddenly. The way to tame this is to fabricate a new throttle arm of about 1.5" on length. If there is an offset in angle you can correct the eith the new arm as well. Once the new arm is attached, go into your TX and adjust your throttle servo travel to 110-120% for both high and low. Once that is done mechanically set up your throttle so that you get idle at low stick and 85% carb opening at full stick. That last 15% opening does not add any additional power. You can fine tune these with the throttle end points but do not go below 100% throw on either high or low and keep the two as close to the same value as possible.


The end result of all this will be that your power will come on more gradually, it will not pull the nose to the left as much if at all and you will not be fighting the rudder. Trust me when I tell you that if you do these simple modifications your takeoffs will become virtually effortless.


Keep in mind that this assumes that both your wheels rotate freely and don't have any weird angles. Don't buy into the toe in or tie out stuff, it makes no difference on our models.
