Waiting for my orders from bricklink and I feel like a dog sitting waiting for the master to come home.

So, more time to fiddle and tweak with what I have to hand, then.

I have given back the shorter driveshafts. Instead, I've redesigned the transmission frame with some didumos level form locking. You can actually notice the gears spin more freely in this setup. I think it's because 5 liftarms stacked doesn't quite make 5L, but if you lock it like this, the distances between the gears are exactly right.

Apologies that the pictures are maybe hard to decipher, it's largely made of darkside bricks and nearly everything is black. Those are black 5x11 frames on their sides, form-locking 5x7 frames sandwiched together. Those sideways frames then give a good solid mount for the wishbones, and somewhere solid to put the ends of all the axles for the 24&8 tooth gears. All with way fewer small connectors and less freeplay.

There are 92907 connectors holding the top frame on, they are really solid like that. This also helps give a tighter spacing for the shocks and rear cowl.

I'm hoping the crank handles in the bottom won't be necessary once the cockpit is built up, but if so then I'll need to find a neater way to brace that section.

The rear bodywork mounts had to be redesigned, but it's all come out nice and sturdy. Bit simpler as I don't need the tilting spoiler.

I test fitted the rear cowl, it just needed the lower rear panels swapped for 21/22 panels to clear so as to the top legs of the sideways frames.

I used some different pieces for the exhausts, as I didn't like that they were only lodged on there. These ones have a 5.5L axle through, so can't fall off.

 

Really really looking forward to finishing and driving it now!

I would love some instructions for this. I've been staring at these pictures for hours, trying to get it done the same way, but I just can't :(

I think I'll stick to the original instructions and just make it like that.

Indeed, building from pictures is hard, but not impossible. I built the whole virtual model and PDF instructions entirely from the pictures in this flickr album.

I've been tinkering with the model more this afternoon.

I only just realised that the O-ring I added on the drive shaft is acting as an elastomer and making the suspension stiffer (very/too stiff).

This revelation came to me while I was fitting a rear diff lock, which I was doing because it had turned a 12t bevel gear from the differential into a 10t bevel gear - also known as a Jesus gear.

True but it gets a fair bit trickier when you're trying to build from pictures where every pin type and 2L axle is just black
