RE: T-28 True 1/5 Scale
Franz, appreciate the Greek history lesson which I really enjoyed reading again and the ton of memories that came flooiding back into my mind from my readings during my early college days, but I am not able to make the connection with the greek adventure and a navy aircraft trainer. Can you take it any further? Smile. Chic

RE: T-28 True 1/5 Scale
Good afternoon everyone, back on the # 2 T-28. I have been working on the wing, and am to the point I will need the landing gear anytime. I've been doing a number of different things, working on a scale cockpit kit, trying in get correct pull on the canopies,(did 6 with on good one), canopy fiberglass framing, so not a lot of visual work, but lots of little things. 5th kit just shipped. Will have to get a new laser cutter on board as the fellow that was so helpful in design and cutting has decided not to get back into the laser cutting business.
I don't know if i mentioned, this second build will be a D model basically and will be done up as a ground attack aircraft with camo upper and grey/white under surfaces, oh yea I have also been working on the under wing pylons and gun tubs.
Here are a few pics of the #2 wing build.
pic 1 is complete windscreen fb frame
pic 2 left wing completely framed up
pic 3 scale wing seperation
pic 4 anti rotation pins and wing seperation
pic 5 flap to aerl. split
pic 6 inboard flap split
Next up I will be installing the aerl. servo mount, flap hinges.
thanks for looking

RE: T-28 True 1/5 Scale
I didn't go into any detail on the canopy problems, maybe someone out there can tell me what i am doing wrong.
Female plug is made of plaster, seems to work pretty good. Using PETG .040.
The first pull looked pretty good with a few minute air bubbles, however this was to be used, after sanding imperfections out, as a cap over the plaster plug and new canopies pulled over that.
Sanded that down, cleaned, and tried the next pull, came out very good. (Thankfully as I had an oder for a kit)
Next one looked good until it started to cool, a ripple developed along the top about 1/3 the length toward the rear. when I pulled if off the mold I found that the petg cap on the plaster had also developed the same ridge. We thought that the cap may have tried to pull up.
Went through the first process again, only this time we left a lip on the base of the first pull and stapled it down to the base of the plaster mold, sanded etc.
Next pull did exavtly the same, forming the ridge as it cooled.
Are we trapping heat? Was the plaster not completely cured? Any ideas, this is way to expensive to keep up at this rate.
Any help on this would be greatly appreciated

RE: T-28 True 1/5 Scale
JohnnyO, rec'd the kit, can not thank you enough for a great looking product. The size and quality of work on that cowl and the canopy pieces is impressive. I'm sooooo happy with your product, I do not know what to do with myself. The T-28B is number 3 in the build que. I have the Bird Dog (DAWG) and the TBF/TBM Avenger (both in RCU Warbirds) to finish first. My T-28B will be done in the Drone Controller color scheme. Will certainly post the build here on RCU when started. Chic

RE: T-28 True 1/5 Scale
Ron, Probably will leave it as just T28-D on the documentation packet, but then again maybe not. Thanks for the heads up.
Chic, Wait tell I have the main canopy fb frame done, should be soon, I finished up the mold today, just need to lay up a frame and make sure everything fits,

well chic, I have been busy with on the build of #2, but it has been on the cockpit stuff, takes a ton of time when you just work on it every so often, I will post pic's of when Iam at on the cockpit and airframe. the fuse is pretty much ready for glass and detail, the wing is frame up ready to sheet, flaps are hinged, aerlirons are hinged, servo mounts are in etc.. however I am still waiting on the prototype gear from Schindin before I can really go much fruther on the wing. I will also up date the build pics on my webpage. www.scalercstuff.com

JohnnyO, take your time. You have produced a quality kit and a complete T-28 cockpit will certainly make this kit even more impressive especially to the scale judges even from a distance. Make sure you have me on your list for the canopy and fiberglass frame when available. This will be my second model to take to the NATS one day. Thanks for your hard work JohnnyO. Chic

thanks Chic, I don't know if I need to add the carbon to the fiberglass canopy frame, just thought it might need a bit of strength in those areas. I do one without, see how it comes out. I have some molds for the cockpit pieces such as side panel and glare shields (top of both front and rear dashs) the side panels are styreen vacume formed and the others are fiberglass. I could draw up the basic parts as they are light ply and balsa, not hard to make at all.

Been awhile, but I'm back with some updates on Trojan #2. Been working on the cockpit and wing structure. First set of pictures are of the progress on the cockpit, still a lot of stuff to make. then we have the wing structure. I am sheeting the trailing edge up past the hinge locations to the wing trailing edge spar. This allows for work on servo bays and retracts at a later date. Speaking of retracts, I am going with electric on this one, Lenny at Schindin Machine is still working on them I believe, but I do have another option in the works for those of you waiting for gear for this bird.
