I have an OS 46 in that Kyosho Breitling Cap232. Its about 5 years old now. Anyway, I have a climb prop on it, a 11X5. Aerobatics are alot of straight up and straight down. My Cap goes up for ever. People are always asking me, " What have you got in that thing ? ". The performance is simlpy great. Same with my T28, it has the OS Max 61 bearing. Folks can't believe it. I really like thier 50's also. I say the best 40 ever made is an OS Max 50 !!! The metals are quality and they last for years. Parts are everywhere for them and easy to get. They have really great support techs also. All my engines start by snapping my fingers on the spinner, amazing to see ! I saw that on discovery Wings. I can recommend OS Max to anyone. Others might match thier specs, but they don't match thier metalurgy or support. That 46 will serve you for years and years and will be plenty hot enough for some sporty planes. Welcome to the hobby and good luck with that Kadet. I like those too.
