Jack and Kolbers , I am just starting work on building my tail on my Firefly I have the wings just about done in Fl. but brought the tail section back to Ma. with me, as I could.
My question to you all that have built a Firefly is, when building the Horizontal stabilizer the inst. manual says to cut 2 , 6 inch pieces of 3/4 tube to incert in the trailing edge where the support cable bolts on, then I look at the plans and they show the bolt for that cable in the center of the 6 inch piece 12 1/2 inches for the end then I look at the plans where it bshows the cables etc. and the bolt is at 12 inches ????????That being I look at the 2 pieces of 3/4 inch tubing with a very heavy wall , about 1/8 inch that are machined to fit inside 7/8 tubing and they are 4 inches ? maybe because they are heavy wall they didnt make them 6 inches ???? or perhaps they are for another application and I am supposed to cut 2 , 6inch pieces as it says in the manual ? does anybody know? Of course I started this on Sunday the day before Labor Day so neither Travis or Brian are at work , but life goes on ! Thanks in advance Chris
Chris,
It has been almost ten years, and I don't remember. I checked my drawing set, and it shows on Page 4 that a 4.5 inch spacer is used in the tail post of the vertical stabilizer. Also, on Page 8, I see the 12 inch measurement with my note of "-1/2". I believe I went with 12.5 inches as shown on Page 2. as I had circled the measurement On Page 2 it says to use 6 inch spacers and I believe I did. I wrote notes on my drawings as I tried to figure things out. If I had not recieved the two six inch spacers, I would have made a note of it.
Will be interesting to hear what you find out when you call TNK.

Jack ,thanks for the input, I did get 3 spacers 2 4 inches by <7/8 and 1<1inch like it was intended for the vertical stabilizer they are machined down but they dont fit inside the tubes I dont see why I should have to "split" them after they machined them ? I will call Brian tomorrow, I knew it was a long time since you built your tail but thought you might know I think they changed the assembly but the book hasnt caught up yet . Probably never will the way things are going. Thanks Chris
