What size gmade did you get for the front? The instructions call for 81mm eye to eye but gmade only has 75mm or 85mm obviously both would work but you'd have varying amounts of up or down travel, more down with 85mm and more up with 75mm

[@rcprinter]

I went with the 75s and I like them.

If I'm not mistaken, the designer of the MK ultra also made a mod to install a Lexan Body of a Rally Porsche, I was wondering if other bodies can be installed, like a Tamiya rally body, for example, a Subaru Impreza. it would be a really cool mod.

I think this is what you were referring to: cults3d.com/en/3d-model/various/team-bluegroove-1-9-porsche-959-accessories-and-mk-ultra-adapters I'm not sure what else might work with these posts but you should give it a go and send pics or it didn't happen! You could also ask over on rcgroups and the designer (lynxman) might answer you here: www.rcgroups.com/forums/showthread.php?2952626-MKUltra-A-free-3D-Printable-4WD-1-10-scale-buggy

What shocks did you upgrade to?

[@rcprinter]

GMADE XD Diaphragms. Love em.

[@multimargejta123]

What is the top speed with this motor?

[@rcprinter]

Sorry I'm not sure. Would also depend greatly on your spur/pinion/layshaft setup.

[@77LaKoS77]

Aren't the belts also available in 8mm? Because on the Discord is a device for print, because you can cut the 8mm belt in two ... from one, get two! 😉 And for the motorplate, i have a .step file from it, so you can include the spacer to the motorplate. When you are interested, let me know, so i can share it with you. 👍🏻😉

[@rcprinter]

Hey that's a great idea! I've been talking with our supplier from China that makes most of the belts we carry in our store and they say the actual belt profile for the schumacher ones I was running previously and that you can buy online is STD. As Lynxman says it probably doesn't matter much HTD, GT2, STD at this scale with 3D printed parts but given the choice I'll probably order STD for the store so that it matches.

[@JoseRamos-su3ep]

Can’t you just put the pinion in backwards?

[@rcprinter]

yeah I totally realized that afterwards... that'd be WAY easier than printing a shim... and yet I always do a shim lol.

[@JoseRamos-su3ep]

Right on!

[@sixtolavalle343]

why is it called MK ultra ?

[@rcprinter]

That's a great question I can't answer. ... ask lynxman on rcgroups forums.

Running on grass is pretty tough on the electronics, too much drag. Watch those temps

[@rcprinter]

Thanks for the tips!

[@Poulpc]

just an idea, but it looks like there's enough room to redesign to fit the 6 mm belt

[@rcprinter]

definitely a possibility

[@radiocontrolcardevelopment7329]

Thanks for tthe video! Do you have a link to the belts?

www.aliexpress.com/item/10000059382581.html - 396mm - 6mm www.aliexpress.com/item/10000059382196.html - 360mm - 6mm Again, though I'd try and find some 4mm ones if I were you.

How big of a bed do you need to print this car?

[@rcprinter]

Pascal says 200x200 is minimum. I printed on a Prusa MK3s
