It's a bit hard to tell but it appears you were able to keep the cylinder head and plug inside the cowl, is that correct? If so, does that engine have a large bore and short stroke compared to say a DA85? All the DA85 installations I've seen have required a good size prop shaft extension in order to keep the engine mostly within the cowl.

Hi Paul- Yes it is a Hyde Mount, I had Merle make it up from templates I supplied.
Wayne- The cylinder head just peeks out the bottom, almost flush.
Nick- The cockpit is a mixture 50/50 of store bought and home made components.

Guys,
I finally have a working mock up for my canopy. Tried to replicate the North American version as best I could. I have a need to remove canopy before flight and this accomplishes that task with 3 clicks. The locking mechanism will not turn loose. The canopy frame is combination of fiberglass/carbon layers and is light, rigid and strong. I will use 5" pneumatic cylinder for retract/close. Excuse the ragged look of pics, but should look better on my stang build. When mounts are not locked the little hole on side does show red.
The last pic is the wood plug I used to vacuum bag the fiberglass for frame.

Thanks to Peter, I got mine finished. Front rails are done as well. What a pain in the behind this is! Looks cool though. The firgelli actuator is slick. Well worth the $70.
Has anyone happened to save a tracing of the cross brace with the holes in it? Love to get a copy of it!

Thanks rdefrei2,
Lots of trial and many errors to get everything working smoothly, but It finally slides open/close smothly. I will be using a removable cockpit tub to give access to critical areas, once wing is mounted, wiring receivers etc. The locking mechanism is similar to old style card door locks and removing canopy is a snap.

Post measurement between canopy rails and I will attempt to draw a template and post 1 to 1 scale. I made mine using .025 aluminum pounded onto wooden and used pop rivets to attach to inside of canopy rail.

Don't have a piture at this stage shall post one later but what I am going to use as a driver is a motor and extended shaft used for electric main gear with a controller
I got mine from INTERAIRCO Aussie

Thanks Chisep51, I will get measurements.
Here is my cockpit completed. I made it removable. I don't think you can ever finish one of these, too many little things to make it look more scale. This is my first attempt at making one. Thank god for iflytaillies! I am not a competitor, so there are some things I took for granted in placement and size of things. The head rest is a block of balsa, when I primered it, some cracks formed, thought it looked good, left them in...

Nice job Doc,
I like the removable cockpit idea. It's a heck of a lot easier to have access to wiring exhaust etc. from top side after wings are installed. I used spring loaded locks (the kind you use for cowls etc) for the rear and cam Locks for attaching the front. I plan to try to redesign my original cockpit tub to eliminate so much air getting under canopy during flight. A lot of air is passing through the fuse at speed. About finishing one of these birds, "I don't think you ever finish, you just stop working on it".

Here is the view from underneath. I put tabs on the wood afterwards to keep it from sliding forward/backwards and laterally. Waiting on my Kolm engine before I can do much more. The Kolm comes with a ducting kit and a servo tray that goes behind the new firewall. I'm using the robbe 2018 for power, I think its probably overkill, but I love the sbus wiring, makes for a very clean install.

Rdefrei2 and others,
I apologize for not responding to Private Messages in the past as I didn't know about PMs until Rdefrei2 made this post. I am trying to use the PM section and will answer all old messages, I promise.

Got a tracking number this morning! yes, the 135 with 270 degree timing. keleo scale exhaust. Hans makes a baffle kit specifically for the carf. Electric start as well. I'll be honest, I am a corsair and FW 190 fan, never really been into mustangs, but after seeing video of the Kolm, I had to have one. Greg Wright happened to be selling his right about that time, so it worked out. As soon as I get the motor and mounting kit, I should make good progress. I have the taylor made decals for this plane, and it will be painted with liquid metal… I will post pics of the motor as soon as it arrives! Its not going to be super scale, just a cool sounding plane with a nice paint job...

LBJ,
You been watching Dave Platt's Vids to. Sorry, I was not trying to take away from Dave, just had a "senior moment" forgot his name.
Doc I echo, post pics, I am not beyond changing engine mounts, would like to hear what you think about the KOLM. I was going to go back to my trusty 3W inline 80 which is somewhat anemic on verticals.
Can some one tell me how to post pics in a reply PM? It wants to just list the URL and the pic is on my computer.

Hello guys,
Hello guys,
Thought I would post some pics of my Stang coming along with the Kolm installation and my reduction. I havnt posted much hear because it takes so much time just working on these things!
I am currently installing Kolm's latest V3 135cc which has become a 155cc, yes 155cc! Hans has made some great changes and now Nikasil coates his aluminum cylinders, which allows him to not use the steel sleeve thus increasing displacement. I can not speak to the performance of this specific engine just yet, as its new and I have yet to test with it. But, I own a V2 IL-135 and did all my PSRU testing with it. It is actually for sale at this moment, so if any one is interested send me a PM. I also own a EZ67cc that powers my 96" Aeroworks Yak, and have tested a customers IL-150 with my reduction as well.
All of the Kolm engines I have tested with start very easy, run super smooth, consistent, and have excellent power characteristics. If I am being totally honest, the only negetive I can mention is that they are on the heavy side, but in a warbird, thats not such a bad thing, right?
Im sure I do not have to mention the sound.....
My mustang should have flown this last fall, but time constraints around the new engine delivery kept this from happening. So this winter the ground tests will be run with a 29 x 28 4 blade prop, then come spring I hope we will be flying. All my propellers come from Mario Seidel from Seidel-props in Germany. My composite duct work will allow the air to enter through the scale radiator inlet, flow forward along the left half of the fues, the 70mm EDF forces this cool air over the engine, then the expanded hot air is drawn back through the other half of the fues while helping cool the exhaust that is an all aluminum 2 into 1 design, mounted in this same area. The hot air exits trough a large duct out the scale radiator dump.
This cooling idea has been proven many times by our friends in Europe, so im very confident it will work in most climates. The airframe is approaching 50lbs because of all the extras, but im not worried about the wing loading at all, and I cant wait to see a 29" 4 blade spinning at a mere 3,000 rpm's in flight. Power on landings and fly it like real heavy metal deserves!
Like I mentioned, the V2 IL-135 is for sale if any one is interested, just shoot me a PM.
Hope this helps guys, feel free to ask questions, cheers!
