Thank you so much for your response. According to the article, you use the formula of 2 oz x cc in. of engine. So for my 2 cc in OS engine I would install a 4 oz weight on the right wing tip.

The Antitorque Device
Twisting forces can do horrible things to a well-built model

Hi All
I believe the prop size and pitch play a big roll in this torque issue , along with the engine.
I just read the "Antitorque Devise" article. I can see how this could work. In fact, the same reasoning is why the muffler is on the right side of a side exhaust engine, to counter (minimal effect) the torque. I think the antitorque devise makes the torque more manageable by "slowing down" the left pull and not eliminating it.
I personally use throttle control and rudder, but may try this out one day when I use a large scale 3 blade on this 109 that may pull this model off the run way. Can only try it to see..
