Eventually I'd like to try a similar body to the M410 on my FF17.

Finally I can hold the prototype parts in my hands:










I hope I find time to start the build tomorrow

Still a lot to do, but the first personal success is already there





Drilling aluminium is a pain. I was really lucky hitting four of five marks
The plastic of the bulkheads is very good. The threads seem strong enough for this project.

Quite possibly my favorite thread on RCTech.

Get yourself an optical centre-punch and a centre-drill. I used that approach for years with a simple pillar drill and found it surprisingly accurate.

Everyone uses a regular senter punch but i doubt anyone removes the lip that forms around the sentering mark. For proper accuracy you should do that.

Thanks guys. Next time I will get the right tools.

Well now finally the moment I (we) have waited for, the full assembled chassis:













Now a direct head to head comparison to the FF-03:







And for the grand finale, the full KR-MF chassis:

Great job wtcc! How is your bumpsteer? The more I look at your servo saver, the more I wonder if you couldn't get rid of it altogether. With the steering turnbuckles anchored so far from the center of the servo, it seems possible that the servo saver is going to become too soft. Plus, using a solid servo arm would maybe allow you to lower the pickup points by 2 or 3mm, thus putting the steering turnbuckles closer to horizontal. Car looks stunning in any case.

P.S. Aluminium screws to attach the motor, seriously? Ok, you're the engineer ;-)

Thank you all

@heretic: The Ackermann is still f***** up. I adress it later with additional cfk plates on the steering hub. That is why my bumpsteer is set like this I will take a look at the softness of the saver next time. Until now I haven't focussed on this subject. This is the T4 x-hard servosaver. Maybe it is strong enough for my lw car? I will check Which solid servo arm in an at least equal length can you recommend?
Motor: Aluminium for life Seriously: I use aluminium screws on my F1 and 4wd cars and somehow haven't had bad experiences with it. Maybe I was just lucky...

The last two days I have done something no RC enthusiast should do: A list with all items he purchased that also includes prices. I made sure my wife didn't see me making it
The list includes all parts the car consists of. I left out prices for my parts, because except for the chassis and the top deck I milled them from carbon I had laying around. For the guys in Europe I can establish contact to Christian Donath if wanted.



Oh, and I was not motivated to calculate the total
