1/72 Broplan ATR 72 500 to ATR 42 300 vac. kit

Recommended Posts

Thanks!

Gaz, no I don’t. I make a 2 part mould knowing the bottom 1/2 will (most probably) be sacrificed to bubble damage but is necessary without a pressure pot. Once the bottom 1/2 cures I pour the top 1/2 then turn the mould over and remove the bottom 1/2 discard it and pour a new mould but with the whole issue now inverted the new mould becomes a new top 1/2 again, but with no bubbles on the master now.

I’ve also made some tricky moulds by using disposable brushes and brushing the silicon rubber material on to the master, allowing it to cure then putting that item in a box and pouring the mould silicon on to the cured rubber, as it will bond to cured stuff with no problem. The main point being to have the part situated during curing so that any bubbles rise away from the master, I don’t care if the mould has air, just not in contact with the master.

thanks for looking and taking time to ask the question

I've finally got the engines glued onto the model. These pictures have them glued in place and being faired in with Tamiya putty. The props aren't attached yet but pressed into place. The landing gear sponson (belly pod is also having it's final attachment points refined as closely as I can get.

Looks like you're doing a great job on this bird. I simply cannot believe all of the flash on those parts! That's alot of work to remove all of that in itself. My hat goes off to you.

Thanks!

Ya...that flash!...I'll watch my complaining next time I'm working on a mainstream injected kit with a bit of flash here or there.

I've started adding the kit supplied photo-etch...hahahahahaha yaaaa right! The photo-etch I'm adding to the model here is left over from Kitty Hawks 1/32 OV 10 Bronco,  more grilles will be added above the ones shown on the top of the sponson (I think for the A/C turbine??) I've also begun fitting the main L/G legs and will add a bit more detailing inside the gear well later...maybe.

After laying on my back on the hangar floor for about fifteen minutes trying to determine what color the gear bay is I settled on white with an overcoat of clear yellow and a dirty brown wash. The brown wash is my interpretation of the anti-corrosive? spray all over the place in there. As well, the rear wall of the bay has a black rubbery coating on it (gravel guard?) anyway, here's where I'm at tonight.

The sponson before opening it up to add the bottom vents, which if I'm going to be honest about, I was going to put in place before adding the sponson but forgot...or I got in too big of a rush.

I fit the upper vents tonight and glued in the gear legs, everything seems to line up not too badly (oddly enough)

beside a model wearing the colour scheme this one will (eventually) be wearing, if I ever get it done.

I have to extend the tail cone, make it round in section (it was ovalish) and add a clear dome

I've always liked the looks of the ATR - it's such a sleek looking machine. Great job on what looks to be quite a challenging kit. Are you going to sell your engines as AM parts? You'd get a few takers I reckon

Wow - I’d somehow missed this. Knowing BroPlan kits and what you started with, this is an impressive display of modelling talent!

Thanks Tom

I was inspired to get back to work on this almost 2 year old stalled project by seeing your B-52 build to be honest.

I doubt I'll be making the engines commercially available, I cant see a market for them other than the 2 of us building this kit...well me and another fellow has ordered one at this time, I agreed to send him engines and flap actuators but He's probably the only other one who'll use them. I made molds so I could build a couple of these models and make life slightly easier for myself by not having to build 4-6 vacuformed engines...

I added a new tail from Milliput, a simple thing that took more than just a couple of hours to fair in and refine and add the tail light (a nose from a 1/48 missile) 

Milliput in place

sanded to shape and filled imperfections

finally sanded smooth and tail light added. It's only on with crystal clear in case I need to remove it for painting or some other silly reason.

I have been following along with this build, I really quite like the ATR-72 and your conversion is very inspiring.  Love your casting and clean tidy work.  Is the kit still available...or any other kit in 72nd .

 

Keep up the great work!

Thank you Anthony

Yes the kit(s) are available through Aviation Megastore I was really holding out for the Scratchaeronautics kit as it was looking like it would be a nice kit (in resin) but having shut the doors and folded, it left me with the model (s) I have here in my stash, I have another one of these 72-500 kits...That reminds me, I bought 2 kits because I knew I'd bugger something up never having built a vacuform kit before and wanted spares. Finding myself thinking I'm "over the hump" I am looking at components I built earlier wanting to fix or refine things. Case in point the landing gear sponson. In my build it looks symmetrical through the long axis where it attaches to the fuselage (it looks clunky to me) It should narrow and taper towards the front and rear and have a airfoil shape viewed from the side. I knew this when I built it and thought I could live with it, in fact I was quite happy with it until the rest of the model started coming together so nicely. My boggle is, how do I fix it? I'm not against removing it (very likely destroying it in the process) to refine the shape...just not sure how to do it with all those compound curves.

Here's a picture of what I'm talking about.

The real aircraft:

I may have to live with it and attempt building my own on the next attempt

I've decided I've got nothing to lose by trying, using the"spare" ATR kit to base the work around, I've begun building my own landing gear sponson. I took a couple of pictures of where it sits as of today (a double rye in a short glass is helping) It's not perfect but looking better than the one I built from the kit with the more aerodynamic shape

(I may have done something wrong with the kit part to have the sides look so much like a canoe)

I'll build this piece up with epoxy and sand it smooth (scribe and detail etc etc) but I'm thinking I like this version better than the kit one...now to finish it and see if I have the nerve to break the existing one off my build or just chalk it up as a learning experience and do a better job on the next one... 

Yes, I'll make resin copies if I get it perfect

Suffering an ATR Mojo failure and needing a break, I've started cutting plastic on the 1:24 Hellcat. It'll be OOB in gloss dark blue with kit markings, although those markings will be painted on. It's a big bugger!
