I don`t want togo against Sig,but I doubt if a LT 40 will go fast enough to give you trouble.That is if you don`t over power it. No doubt you will be using c.a. type hinges, they should be tight enough.Use 6 for elev. 3 for rudder and 8 for ail. Have built 2 from kits and 2 ARF`s all flew great. An LA 40 is a good power plant for this plane. Have a lot of good memorys of Greenville@ Donaldson AirForce base.Plus my wife is from there.She is up stairs now with her nose to the window,tears in her eyes watching it snow. good Luck AMA14958
