Thats good to know
Is the 7.1 lipo compatable as well ?

Since all the new HL tanks come with a Li-ion battery, lots of folks have run Lipos on them. I still run Li-ion batteries, but I use bigger, higher capacity versions than what come with my tanks. I only use the stock HL batteries when I run out of my aftermarket ones. The HL MFUs can take up to 12V, but I haven't personally pushed one to that voltage. I typically don't like running my electronics at the ragged edge of their capabilities. Tends to lead to things like letting out the "Magic Smoke". Once the smoke comes out...there's no putting it back in (unless you have mad electronics skills).

Maybe what i should have asked do the newer mfu's that run li-on have a LVC (Low Voltage Cutoff) for lipos ?

That's a lot of the big pieces assembled already:



Much easier to install the rear LED's at this point already:



And brass screws for the fancy parts



I intend not to paint the model afterwards. The filament is Bambu Lab PLA Matte Dark Green.

Wow mate thats really good progress on it

More progress: my AFV now has road wheels, drive sprockets & timing belt driven gearboxes, idlers & tensioning systems. It may not look like a lot but trust me, that's a lot of work right there. Lots of trial and error as well. I think I took off the idlers 4 times to correct assembling mistakes: the sequence of things would be what I did wrong the most I'd say.





And a bit of color reference, although it's hard to capture subtle differences in photos.



1 = PLA Matte Green (Bambu Lab)
2 = PETG Forest Green (Bambu Lab)
3 = spray painted Olive Green (RAL 6003)

I printed the sprockets in PETG initially but then decided to go for ASA which I then painted. Same for the idlers but they might just stay black. I refuse to take off those f**** a fifth time

you could just brush paint the idlers ?

I could ... but I'm still mad at them and I'm just too stubborn at this point. I want to move on

Yeh can understand that mate
