I was hoping that someone from Sierra Giant Scale would be there, but no dice. Oh, well, the homebuilt set of working gear is beginning to look more and more attractive. I'm looking at what should work best for the damper and plunger setup.

C’mon Bill, just do-it and git’r’done

All kidding aside, with your building talents, I have no doubt that you will be able to build a really nice gear.
The gear that SuperCubMan put together looks pretty darn nice.

On a different note: I have started a build thread for my Citabria Pro.

http://www.rcuniverse.com/forum/m_7426963/tm.htm . This will be my first practice build in preparation for the WACO. Not to mention the first time I have ever put my work out there for everyone to see

. I will be trying out several building ideas along the way to see how they work for me. Not to mention, I’ll try to apply what I have learned on this thread into building. The thread is in it’s infancy right now. But, I would like to have you guys drop in on the thread now and again and keep me pointed in the right direction

. Just for the record, this thread (WACO Brotherhood) will remain in my daily routine.

Hello all

Bill Thanks for all the great Top Gun pictures you posted. I wish I had more time to talk with you I really enjoyed meeting Janelle she’s a fine lady.
I also meet Mike Barbee a first class person all the pictures in the world can’t compare with seeing his Waco close up the craftsmanship in this aircraft is unbelievable.
So here’s where I’m at I hope I done this right. To mount the bottom wing and check the dihedral I first leveled up a peace of 4” aluminum on my table then I leveled the fuselage with the wing over the aluminum checking the wing tips I was within a 1/16 in then setting the dihedral gage on the wing it was almost dead on 0 deg. I hope this is good please let me know what you think. Then I’ll start on the top side.

Well I made my first attempt at doing a wing fairing

, but for some reason it just doesn't look right. I was looking at a picture of a 1934 YMF-5 NC14067 and it looks close, but not sure. I was trying to do the wing fairing like the one on NC14081, but failed badly[)]. Here is a couple of pics that way one of you guys can let me know if I need to make any adjustments to it, at the moment it is just rough sanded to shape haven't done any smooth sanding yet. I figured that I would post these pics before I started the other side.

Dan,

Does your kit call for zero on the bottom wing? Look again. Your method is good, but I'm sure that you missed the incidence call out.

Rick,

On mine, I build the fairing from the bottom of the wing, back to the transition point, and then fill the top to blend. Looks like you tried to use the top of the wing and that's the reason that the fairing looks as though something is missing. I think that if you add a filler piece to the bottom, and then continue the upper section until they blend together, you will like the look much better.

I checked my plans and they show top & bottom wing at 0 deg incidence and the stabilizer to be 2 deg positive. If I have to change the wing now would be the time to do it I don’t have my wing fairing built yet.
I hope I don’t have a set of bad plans.

Dave,

I believe you need to extend the fuselage side of the fairing back almost back to the bulkhead just to the rear of where you ended it now. The bottom stringer appears to be correct, just a bit short to give it the long and lean look of the early fairings. From the photos I have looked at on the NWC site, the fairing seems to end slightly behind the wing trailing edge. Take a look at the NWC photos of N 86Y (pic 30), N 14051, N 14082 (all on page 2) and 14134 and 14132 (pics 64 & 68) on page 3.

I can understand the problem trying to do the newer style fairing as seen on NC 14081. They end 1 stringer above the corner and have a much greater reflex on the underside and look heavy and thick in comparision.

An additional thought on your rudder question from last week. The original U/YMF-3s had a slightly shorter and smaller rudder/fin originally. My understanding is that most had them replaced with the larger "-5" rudder/fin.

Dan,

I haven't looked at the plan for some time. I just checked, and if you are on zero to the datum line (crutch) you are good to go.
