My vote is for the Nav lights! You've gone to all this work so far, why not a little more!

I have not had as much time to work on the T-34 lately, but I am still plodding along.
Decided to change the flap control system. I just did not really like the "Y" thingy. Looked cheesy. I built a bellcrank style, control that is quite a bit more positive.

The word that comes to mind is "robust". I like it!

vis-a-vis lighting - nav lights are not normally run in the daytime - when you will be doing scale flight. I will be painting in unlighted colored wingtip nav lights, but I am going with all (3) strobes, which ARE often run in the daytime for collision avoidance.

Yeah, went outside and watched them for a while yesterday. Most, but not all had 3 white strobes going. Did not see any with nav lites. When they were close to the field, the landing lites were on, on some birds. I think I will just use s set of strobes, that are on all the time. Found a guy who can do a set of three random flashing white LEDs, that plug into the receiver, and come when the model is turned on. Draw almost no power, and only $15 a set.
Just had to see what it would look like this morning. Nice sized model, not small, but not too big. Sure is a lot of cockpit room to fill.

Terry,
I found a good source for T34-C cockpit details: http://www.airnorthwest.net/specops/t34c/P-307.pdf.
You can download the illustrations you get interested on.
Enjoy!

Terry:

Back about post 21 or so, I see that you have the wingtips on your wings. I haven't worked much with vacuum formed plastic. Can you give me some hints as follows:

1. What do you do to prep the plastic? Do you roughen the surface where it attached to the rib?
2. What do you like for adhesive? Do you epoxy them on or use something else?
3. What is your preferred primer for the V.F. material?

Thanks!

Terry,

If you want a good illustration of the layout of both cockpits including the instrument panels, I still have my old NATOPS manual. I could
scan the pages and send it by e-mail.

fliir,
1. What do you do to prep the plastic? Do you roughen the surface where it attached to the rib?
I just use some 60 grit paper to roughen the glue surface.

2. What do you like for adhesive? Do you epoxy them on or use something else?
I have used epoxy, Goop, RC 56 canopy glue, and thick C/A in the past.

3. What is your preferred primer for the V.F. material?
I just use whatever I am priming the model with.

Installed the retract rails and started sheeting the bottoms of the wings. Slow but sure.

Been working on the retract doors today. The gear doors that come with kit a very nice heavy plastic parts that look nice. And they have the correct contours molded in them.
I cut out the doors and cleaned up all the edges. I located the exact locations before sheeting to be sure I would not screw anything up. So now it was just a matter of laying the doors down and tracing around them, then cutting the sheeting.

Next, I installed all the hinges on the doors, as set out in the manual. They are just tacked with C/A and some screws for now, so I can disassemble them later. I had to change the way the inner doors were actuated, as they were designed to work off the mechanical retract servo. I have just added a control horn and a 1" travel air cylinder. I will use a UP-2 control valve from Ultra Precision, or a pair control valves, with a door controller, to actuate the gear and doors. the inner doors work like a Mustang, with doors being closed when gear are down. The outer doors are actuated by a piece of tubing that slides on the wire attached to the strut. Right now, I have clamped it on with a hose clamp, but will make a brass strap to hold it later.

Finished the gear doors on the opposite wing this week and started on some of the finish work.
I shaped the leading edge and added the L/E cuffs the blend to the fuse.

Also worked on the gap fillers for the ailerons. This was done by sanding a groove in the T/E with a special tool I built, then laying a piece of 1/32 ply in the groove. Really simple setup that is very strong.

Did you consider any other hinge and actuator system for the ailerons?

I would prefer one aileron per servo, but I want to retain scale hinge lines and concealed linkages...

I thought about using seperate servos on each aileron, but I really wanted to try the scale system. Every other model I have built in the last 10 years, or so, uses 2 servos in the wings.

Looking pretty good.
The model I am replicating, does not have the corregations on the stab. I have seen a lot of "C"s that do, but all the planes I have seen, at the nearby base do not. However, they do have the corregations on the rudder & fin. Not sure what the deal is.[&:]
