Lou,

Thanks for all the valuable info. You answered all the questions I was going to ask next.
Yes I believe I can get the needle valve assembly and the venturii from Tower Hobbies.
I have a Brodak Cardinal that I plan to put the engine in.
Up to this point I've only done a little bit of U-control flying but I'm defenitely hooked. It's a lot of fun.
I'm going to take your advice and seek out some of those Jersey fliers and see if I can learn how to do this right. I have a couple of old Fox 35s but I would like to see if the OS is much different as far as power. Hopefully it will fly well.

Maurice
