Ebay? ok. I couldn't tell from the pics how old the kit is but if it's one the older ones, there is one modification you may want to consider. The glass inner walls of the air intake tend to buckle in a lot (flex) at high speeds. You may want to consider gluing a small diameter dowel or piece of lite ply between the upper and lower inner walls of the intake to help eliminate this problem. So, if you were looking straight into the air intake, you'd have a piece of wood mounted vertically, joining the top and bottom of the air intake. Just a thought. With regards to the 18"NYROD, my guess is that they suggest you use a nylon rod possibly for your steering linkage to your nose wheel. Check your instruction manual to see where this NYROD is used. Basically, it's a piece of plastic like material within an outer plastic like sleeve that you'd glue in place. Clevises would attach to the ends of the inner rod to attach to your servo and whatever mechanism you're gonna use it for. Personally, I prefer a pull-pull system which uses plastic coated fishing wire. Let me know where the manual indicates to use this nyrod and i'll point you in the right direction. You can also consult Shaun Evans of Yellow Aircraft. He's very cool and most knowledgeable with the Y/A kits. You can also reach him at [email protected]. Keep me posted. Have a good one. Richie
