Wow, Fred-
Thanks for all the information. I'm inclined to try to go with a hard tank and a uni-flow setup, if that will work on this little plane. Excuse my ignorance, I'm new to the c/l scene, but having a ball. My OS.40fp that my buddy setup on a uni tank runs so perfectly, never a problem with it. But Eric and others swear by pressure for the 1/2A's, and who am I to argue? My buddy/mentor is an ex combat guy, and he says pressure is fine (but I forgot about the course needle on the Norvel's).
I think some of what I decide will depend on what the front of the plane looks like....
I'll have to bust out the plans and get back to you, but thanks for the offer, and reminder of the needle issue. You've already saved me time, trouble, and money! Thanks so much.
Kind regards,
Chris (who flew his buddies 80mph wing this morning)
