I finally bought a Cap and hope to use my 3w24 for power. I assumed the firewall was not attached, but it definitely is on mine. Now I am faced with cutting at least three quarters of an inch off the engine box and attempting to locate the 3W on the thurst line. Ouch! where is the thrust line? I read several articles stating that right thrust is not necessary with computer radios where it is prefered to mix in some right rudder with high throttle. I have many decisions to make here and could use some help for the experienced Cap builders on this thread. Thanks, Looper
