Another page of instructions completed.
Exhausts installed, engine installed in chassis, coils added, chassis extended for brakes and suspension.
Getting the engine in and aligned was troublesome. Very tight fit, engine mounts weren't perfectly aligned, and so engine not straight. Draw back of self tap screws for holding parts in place. Once the hole is wrong that's it. Anyway, I think we're there but won't know for sure until the wheels are on.
Plenty of remedial paint work required for reset joints in the chassis - another drawback of white metal frames.
Step 2 was installing the exhaust headers. Didn't get a photo before the engine went in the frame.

Step 3 was installing engine in the chassis. As said a very tight fit. The photo above shows the engine about 1mm out of alignment. I needed the second stage frame to pull in back in line. Though I have learnt a lot about the order of things. For example, despite instructions, don't install engine mounts before it goes into the frame. If I build another, I think it would be a way lot quicker.



Next step was gearbox and exhaust pipes


Last step on pg2 is stage 2 of the chassis for rear body work and suspension and wheel mounts. The unpainted piece is to help keep it square and part of the third stage of the chassis.


I think once the chassis is complete the build should go a little faster.

cheers
Michael

Hi Michael,

Your progress sure looks good, and thanks for posting the series of images.

Your challenges along the way sound familiar. Thinking about this a bit, in the context of my experience building MFH kits at a smaller scale, and your comment about the engine alignment being out by about 1mm made me wonder. In a regular kit this slight misalignment might not matter, here though, you just can't tell.

Maybe the combination of slightly out of aligned motor mounts, wrestling the engine in, and the hit-or-miss challenge with the self tapping screws, could also lead to slight torquing of the white metal cage or some part of it?

The torquing speculation/question comes to mind because at least on the smaller builds, I found it was hard to see if or where things were slightly bent. Meaning if something, or some combination of parts were slightly bent, an error could "grow" without you (or me!) being aware that the potential problem even exists.

On my 908 build, it turned out that the "torquing" didn't affect the car sitting flat on all four tires, but it did result in headaches getting the body to sit flush, and I could not identify precisely what the problem was.

I noticed you were able to install the diagonals over the top of the engine and they look to be straight! congrats on that! Maybe the chassis is indeed all squared up!

So - we are all counting on you to solve this challenge and to tell us how you did it! haha - Keep on building!

Cheers,

Nick

Hi Michael. With respect. You picked up one of the most complex Hiro Kits and you do it justice. The engine is a piece of art, hope with some weathering, it will look like the 1/1 scale.
Keep them coming.

I'm just blown away

The installed engine/transaxle into the chassis is beyond words. Like I said in the GB post, if one didn't know that this was a model, they'd swear that it's a picture from a real restoration. It's that good.

Absolutely stunning Michael! I've just gone back over and re-read this thread from the start a couple of times and I keep picking up new details that just look so real.

Keep up the great work, and keep the updates coming!

Thanks Nick.
It's the down the track that I worry about.
A good way to describe the chassis is a six sided box. Only the front facing section of the chassis, which is more substantial with the members being square and thicker than the rest which is round, came out of the box flat. Every side had to be straightened, the drawback I guess of white metal. This was especially so with the rear section which holds the engine mounts. It took me a while to figure out how that should look let alone fit.
The more I worked on it I just decide that MFH had not provided the right size for some pieces. The top diagonal bracing struts, where just not long enough. One is brass rod, the other had an adjustable extension pin put in so I could adjust the length to fit once the engine was in place. Then I filled it in and painted it.
Another example is the second stage chassis on the right. The lower diagonal had to be slightly curved to get around the transaxle. The engine is now sitting straight in the frame so I think from a design perspective it was never going to fit. It may have repercussions for the storage boxes in the next phase.

cheers

Cheers Robert.
The weathering of the engine is giving me plenty of pause for thought. I will probably start lightly and get some feedback. This car had a pretty short life and it's hard to find colour photos of the engines after use from the original cars.

Joel,
Coming from a Porsche fan I will take that as the highest form of compliment. The kit does take a fair amount of the credit and it does look good once you have wrestled it in to place

Finally, finally, finally...
It is two weeks since I posted this photo


What a colossal stuff up on my part.

It took me way to long to figure out that I attached the chassis cross member in the wrong slots. The side bars should have been spread about 1cm wider each side. The mistake was simple to make because MFH had only put slight dimples to indicate the attachment points (which had to be drilled out as usual) and the existing holes looked just right. So much time wasted trying to understand why things didn't fit before I discovered the mistake.

As you'll see a fair amount of damage done to paint work and attachment points that will need to be fixed. Anyway the engine section is complete. In these steps I finally correctly added the third stage of the chassis, the suspension and drive parts, and the requisite storage. If you don't know, LeMans cars had to have a spare wheel and storage, hence the boxes.








You may have noticed the red is quite bright. I think I will need to weather the engine area. I had been debating whether I should but it may also help disguise the mess I have made of the chassis paint work.
So the cockpit is next. More tubular framework
Still, a whole new world to explore.

cheers
Michael

Some extraordinary works going on here. Bravo. Takes a lot of courage to pick up a Hiro Kit. You're doing great!
The year 2021 will be dedicated to my Hiro Kits. Going to build the Monaco GP MacLaren Mp 4/4 cars. Training and race version Senna used 1988. Best cars ever designed IMHO.
Looking forward to your next update.

As Nick said, it's really neat work and it's hard to pick up where the rectification works were made.

Jan,
That's going to be one duel epic build for sure. I'm completely in agreement with your that the McLaren MP4/4 were the best of the best, or darn close to it.

It will be a challenge Joel and Damien. Have the kits for about 5 years now. Made a start, but put it away because the mindset wasn't ok the finish such project. So now, first finishing my recent builds, campaigns and continue improving my work / hobby room, I will start my builds. In preparation I will start a " research & building thread" somewhere round September / October I guess and have good year of building.
Now back to this fantastic Porsche Build, otherwise I'm hijacking it.

No problem Robert. It would be great to see another MFH build here and the McLaren MP4/4 is a good a F1 car as any.
Thanks for your kind comments. I understand completely your comments about mindset and it would certainly help that you are keen to build the McLarens. I think if I had not invested so most energy and research into this build I may have shelved it to come back to but I am determined to see it done.

cheers

Thanks Nick, I learned to ditch the macro and go with the wide angle. All sorts of sins can be hidden that way
As you know a builder always knows the flaws in his build and they will always be glaringly obvious to him or her and invisible to all others.

Too kind! There is more to come at the rear once I get the cockpit attached as the fuel tanks and pumps are hung off the sides.

Well here we are at the front.
Some good news. MFH have cast the floor of the chassis into the resin. Given it's triangulation that is a big plus.


I started to test fit the frame above. It was almost Tamiya-esque, a mere hour to convince these five pieces, after some questioning of their parentage, that they could fit together. Or maybe I'm just getting better at it.



Hopefully I have avoided the hubris curse because there is plenty more to go in.

That's a neat looking piece of resin casting! Good work on the tube frame continues, and I'm very pleased to see that the language didn't cause the parts to curl up. I'm fairly certain that it's come close a few times at my bench

Cheers, D
