The engines in class I &II are about the same. Nelson is one exception. The Nelson 40 is king of class I and the 36 version of the 40 is on top of profile. As for class II the good old Rossi 60 is hard to beat. I think if you were flying something with a slider then you are good to go. Use your old engines and fly on.   Mike

The Rossi 60, any version would work for class II, but would not be usable in the Brobak Skyraider. Profile carrier has a maximum engine size of .36. I recommend you get a Thundertiger .36 pro for the Skyraider and get involved in carrier using that combination. Later on you could build something from plans for the Rossi. Tom Wilk has a CD for sale with all the carrier plans ever published. Print out what you want to build enlarge them and build! His web site is    www.cpinternet.com/~tawilk36   

 OK Any 60 is too heavy for that airplane regardless of what you are going to use it for. Find a .29 or .35 for it and it will fly great! Fly on

Yes I have seen them used!

when i originally made this post i was considering getting back into carrier again.i always loved building and designing my own models. the first model i designed was a 36 in. guardian which eventually became the sterling guardian.i also published 2 designs in flying models. the profile kingfisher and the 15 seagull.when i quit i was just burned out.i flew stunt for awhile then my hands started shaking.i stopped building but i still could fly.when i retired my wife talked me into going to a doctor.he diagnosed my problem as essetual tremors and a touch of partinson desies.when i describer that i wanted to build a class2 carrier ship to the doctor and how much it pulled he advised against it.he said that i would shake for a week after i flew it,so i have decided to sell my wallick ops 65.bob zambelly posted it on ebay for me.it has about 45 min of running time on it.the best highspeed time i got on it was 16.8.it idles reliably.the ebay no is120098329536.i will be happy to answer any questions.  stephen dinerman
