I appreciate the replies.
All -4 owners know who Dave is. He's the -4 guru. I know his are flat, but he has many many mods to go with it that, honestly, I'm never going to do. I do love his plane.
vlittle, thanks for that tip. I bought, not built, so I didn't know that could be an issue. I'll pull the existing ones off and check.
Wood....8 kts??? ****....that's a huge difference for just a wrf. Were flight conditions the same?
My whole purpose is to outrun the current RV Blue SARL champ. He flies an -8, has work into it, and is about 12 mph faster than I am. If I can make another 13 mph...I'll be happy. Also, mine is not a fastback, and I love flying it too much to be grounded long enough to convert it. And, I heard the canopies are nonexistent now anyways.
Again....thanks for the input. And, they DO look fast. So, I'll probably make a set and try them out. If it is slower, I'll put the "pretty" ones back on. Lol. I'm all about that speed.
