I put two more flights on the T-38 this past weekend. The only changes were i added 1 pound of nose weight to help soften the sensitivity a bit (it helped!) and i found one of the left main gear mount rib glue joint had cracked where it bonded it to the upper skin, so that was fixed. I also added 2 1/2 seconds to the gear sequence for the doors to stay open longer.

Flight #4, all of the gear finally went up and it looked amazing! Of course, no one got video of that flight.

Flight #5, the left main got stuck half way up. Performance is still pretty good though and I am getting more comfortable with the model as a whole. It needs some adjustment in the stabs as it has a rolling tendency with more than half elevator deflection, so that is on the to do list for this winter.
Landing is pretty entertaining since it uses about 60-70% power on the landing approach.

Here are two short clips of flight #5:

Looks like your getting CG better. Hopefully your gear retraction is almost solved

i ordered a new set of ER40's for the mains as a last ditch effort.... i'm going to pull the left main back out tomorrow and completely disassemble, clean, lubricate and reassemble to see if that fixes it.

Nice scale size choice for this plane. It has nice presence in the air. Looking forward to seeing the cockpit to finish off "The Look". By the way, what thickness plywood do you use for your projects?

It varies. This one uses either 1/8 or 1/4”. 1/4” for the gear mount structure and horizontal stab bulkhead and 1/8” for things like equipment trays.

I got the printed forward cockpit parts printed a few weeks ago and finally got the time to test fit them to the fuselage. Things fit very nicely, so now i need to get the tooling for the tub and glareshield made up so i can layup the fiberglass pieces for that.

Vey scale, Great Job!

Cockpit details look good. Are those trees as close as they look on video?

the last videos posted? No, they were pretty far out there.


Im prepping materials and planning to lay one or two arfs up this fall to sell, the construction to be done will include painting, canopy/hatch attachment, equipment install and gear door hinging. Will include a 200-240size tailpipe, bypass, kevlar tanks and a complete gear package. Price is comparable to similar sized models. If anyone is interested, send me a PM. These will likely be the only two i sell.

Wow! very nice. the seat and cockpit at that scale really adds to the project. will you attempt any of the crazy canopy hinges?

invertmast

My Feedback: (23)

thank you!

i do plan to torture myself eventually with the canopy hinging. The forward one looks to be relatively simpe, the rear one, not so much.

After removing everything from the other day so i could raise it all 1/2 and inch, The forward cockpit is essentially done. I need to model up a control stick, but i will worry about that once i start doing the rear cockpit after this years flying season.

Jayrockland

I was thinking If you cant make it mechanically functional, worse case scenario you could hinge conventionally and just design the the scale part as a follower mechanism? either way, this project will be way over the top.
