I have an Airmaster with warp drive blades. I note that some people have rounded off the corners on the tips of their warp drive blades. Is this just for cosmetic / safety reasons or is there any increase in performance by doing this?

I hope to replace the hose barb banjos on my fuel pressure regulator with AN-4 sized banjos that I have acquired from a local auto racing supply house. They could supply the fittings but no copper washers. Anyone care to comment on the plan? Good building and great flying, Bob Borger Europa Kit #A221 N914XL, XS Mono, Intercooled 914, Airmaster C/S Bob, We evaluated using AN banjos and here are our findings: The Rotax banjo fittings are for use with M10x1x19 banjo bolts per Rotax parts manual. You can buy the 10mm banjos with AN-4 flared attachments from Summit Racing under the Aeroquip or Earl brand. The washers are 10mm "crush washers". You can get them from Lockwood or you can get aluminum ones from Summit. After all the research, we decided against this mod for the following reason. The AN-4 ID is 4.35mm while the OEM banjo ID is 5.85mm. The mod would reduce the ID by over 25%. The effects to the overall performance is unknown but we do not want to find out the hard way. Perhaps you can ask Lockwood when you attend the maintenance course and report back.

These were shiny (I assume stainless steel), chrome-like in appearance with very thin edges - almost sharp. The ones I got from Aircraft Spruce were stainless steel but kind of dull gray steel in appearance with thick edges, maybe 10-20 thou. I use them for my cowl retention and noticed one missing (must have forgotten to tighten it). Does anyone recommend a source?

Perhaps you can ask Lockwood when you attend the maintenance course and report back. I was going to make exactly that measurement tomorrow when I get back to the Europa. That seems significant. As I said, I wasn't going to replace the fittings until after my Rotax 9xx class in December and I had an OK from Lockwood in any case. I will report back after I have spoken with the Lockwood folks. I still need to get up to meet you folks one of these weekends.
