Here is a Little cheater method I have used to counter Engine thrust and high speed climb, If you have a programable radio set upa mix between the throttle and elevator so you get a slight down elevator as you increase throttle, the same will work for engine torque as well, The will be a slight delay for the high speed mix untill the airplane comes up to speed.

When using down thrust or the mixer to counter a high speed climb be ready for a fairly sharp climb When you chop the throttle, the airplane will still be at speed .

If you want to know more about the use of wing angles and down thrust ask the Free Flight Guys, They use it exclusively to control climb and glide.
