denders Posted October 14, 2023 Author Share Posted October 14, 2023 Thanks, guys, for the offers/suggestions. I found an Engines and Things HA-109 in stock at Kitlinx and thought I would see how that looks. As Thierry suggested, there isn't much visible in the cowling past the propeller spinner. I know it's not exactly the correct engine model, but it's seven cylinders. It looks like it's cast metal, so I'll see what it looks like when it comes.

All the ones I saw from them were made of a metallic grey coloured resin. Troy Molitor 1 Link to comment Share on other sites More sharing options...

I thought it mentioned E&T closed up. Link to comment Share on other sites More sharing options...

I thought it mentioned E&T closed up. Yeah, they closed up at the end of last year IIRC, and had a closing down sale. I bought a few items myself, and at the time, there was mention of the masters being up for sale. Given the age and general crudity of the parts by today's standards, I can't see there being much interest. It won't be long before most of these engines are available as either 3D prints or STL files in multiple scales, and probably from multiple vendors. And based on what I've seen so far in that space (3D-printed engines), they'll blow old-school resin parts away. Kev Link to comment Share on other sites More sharing options...
denders Posted October 15, 2023 Author Share Posted October 15, 2023 Yeah, I actually saw a blender 3D model of an Ha112 when I started searching for information the other day, but I didn't look at it further, as in was someone selling 3D prints of it. But really, in this case there isn't much visible, so I'm going to stay the route I'm on. R Palimaka, Loic and LSP_Kevin 3 Link to comment Share on other sites More sharing options...
denders Posted October 23, 2023 Author Share Posted October 23, 2023 Well, this came in the mail today. It looks very nice. But.............. There's no way it fits inside the fuselage parts without cutting off, minimum, all the rocker covers. Looks like I need to get a Ki-44 kit to use it in. I guess I should start a 3D model and print it. Time to pull out what info I have, take some measurements, and get to work.

Loic Posted October 23, 2023 Share Posted October 23, 2023 Sorry to read last news... what is the diameter of your engine ? Do you know if the hasegawa ki43 / a6m would fit? Link to comment Share on other sites More sharing options...
Troy Molitor Posted October 23, 2023 Share Posted October 23, 2023 Dave, I can send you a Hasegawa Ki-44 engine if you can cast one for yourself and an extra one for me? Tennessee volunteer at work here? LOL. I just obtained the Razor back Ki-100 Alleycat conversion. Loving your efforts going on here. Link to comment Share on other sites More sharing options...
denders Posted October 24, 2023 Author Share Posted October 24, 2023 Troy, thanks, but the problem is that the E&T engine is the type used in the Ki-44 and it's too large in diameter for the Ki-100. So, I imagine the engine from the Ki-44 kit will be too large too. I've actually spent a good part of today working on a 3D model of an engine to try printing. And I've been looking at how to get the 2nd row of cylinders represented and still have an easy way to mount the engine in the AlleyCat fuselage. This unfortunately is the only good photo that I have of the Ha-112-II engine. (MMP "Japanese Aero-Engines" by Goodwin and Starkings) I've since noticed what Loic was mentioning about the pushrods for the second row of cylinders. Anyone have some other decent photos? I'd like to have a better idea of how the gearbox looked too. D Bellis, LSP_Kevin and MikeMaben 3 Link to comment Share on other sites More sharing options...
denders Posted October 24, 2023 Author Share Posted October 24, 2023 I've been blessed with some additional engine information, so I'll see what I can model up that's reasonable and try printing it. Troy, if it matters, I've also had it pointed out that the wing was moved forward 80mm on the real aircraft, but AlleyCat doesn't seem to have accounted for it. That's about 2.5mm in 32nd scale.

Troy Molitor Posted October 26, 2023 Share Posted October 26, 2023 2.5mm (scale) noted Dave, Many thanks. Looking forward to you showing us the way forward. I'm also curious to your engine solution. Never ending but seems doable. Link to comment Share on other sites More sharing options...
denders Posted October 26, 2023 Author Share Posted October 26, 2023 Wellllll...... this is where it's at, atm. It's not a thing of beauty and there won't be much visible inside the engine cowling with that spinner that was used on the Ki-100. It's not rally accurate as far as the cylinder head go. It does show the 'different' arrangement of the pushrods. Note, btw, the wireway for the plug wires is in the back of the engine. The wires come through between the cylinders to connect to the spark plugs. I haven't looked at it, maybe there isn't a wireway and it's just a bowl of spaghetti from the distributor. I've not printed anything like this yet. I still need to model something for the governor. I need to break it down into printable pieces, like the cylinders. I'm thinking that the fins on the cylinders in theory have an acceptable thickness, but I'm not sure yet how they'll actually turn out. I'm figuring on having to redo the cooling fins. This is much more (depth) than the AlleyCat piece, so I'll have to work on being able to mount it too. The indent in the front of the gearbox is just there as a 'starter' for drilling a hole for the prop shaft.
