Hi all, and thanks for the many kudos.
I'll address the cooling issue at the end of the personal responses.
Shawn: I'm using 1/32 ply doublers, but I'm fairly certain that 1/64 ply would suffice. Yeah, it's dangerous for us to get together on the phone; our conversations are wide ranging and long!
I really enjoyed our chat the other day, and yes, I love the new Taylor. I live less than two miles from the Martin Guitar factory and yet bought a Taylor. I tried the Martins, and they are very nice, but the Taylor is just so darn easy to play! I'll send you a photo of it later on today.
Crist: Wow! Such a compliment from you on mounting profile motors is humbling. I know that you've done a bunch of them and they all looked and worked great.
Jose: I'm happy to hear that my etchings and illustrations have helped you. We've known and corresponded with each other by mail and internet for many years. Here's hoping we get the chance to meet in person before too long.
Cooling: There are several ways to address cooling here. As mentioned, a Tru-Turn Turboflow spinner could be employed. Or, you could use a smaller diameter spinner and have an annular inlet that would allow air flow into the cooling slots. I have found on the profile nacelles on my test bed twin - which are done in this exact same manner - that cooling in a profile model is just not required. The motors on the twin come down COLD! Not luke warm, but cold!
There must be a lot of "spillage" around the back of the nose cone area that hits the motor and keeps it cool. I'll let everyone know if this is not the case with the RD-1E.
Thanks again - Bob
