I have bought an old Flite line Sneeker kit but have decided to not use the the wood in the kit and scratch build it. All the wood is cut and ready to build now. I do have a question about this kit. What bellcrank do you use? This kit recommends a 3” metal one and my LHS only had a Perfect 3 3/8” BC number P223. Will this work? The plan also shows 1/8” tubing at the leadouts. Any suggestions on what to use there? I bought the Sullivans braided lead out kit and was thinking of using the yellow tubing for this but not sure it will work. I appreciate any advice, Tim

That is a possibility and I did I watch the video on installing one but I would like to jerk this one close to the original design as possible. It is going to be somewhat difficult to do for a plane that was designed in 1962 and kitted the next year. Hardware for these planes have gone through many changes and my experience, as a kid, was limited to .049-.09. Looking back, I am surprised that my planes actually flew with my crude glue and building techniques! Lol Tim

I'll mail you a 3" fox bellcrank if you want. I don't use them for planes I actually fly. I haven't had one fail, I just like the phenolic or nylon better.

Perfect bellcranks I've seen lately brag about their alloy on the package, so it may be improved.
.027" is plenty of leadout wire diameter. A 3 3/16" bellcrank is better than 3" if it fits.
Squished 3/16" brass tube has less friction and more gluing surface than 1/8" tube. Don't use aluminum tube.
If you fly by current rules you'll need .018" lines, last time I looked. The Sneeker was probably designed for .015" lines, so you'll want to locate the leadouts 1/2" farther aft than the location on the plans.
