MT410 Build -- Lots of Upgrades and Stuff

[devnull]

Nice build! I have some custom made Kydex mud guards if you are interested. They are wider than the ones Tekno makes and they don't interfere with suspension motion.

Due to living in a city and not really being anywhere near a track mud guards won't really be needed at this point. I do appreciate the offer -- thanks!

I might be following up on them in the future, as I'm sure I'll be buying another truck at one point or another, one I plan on being able to run in dirt/mud. This one, with all the electronics, isn't a good candidate for that.

I did the exact same thing. lol

Yeah, when you're working on a build and you have to stop (well, not really, as there are other things that can be done in the meantime) due to running out of diff fluid, well, it's frustrating. I have plenty of that and just about everything else reasonably imaginable now for maintenance so I'm hoping that won't happen again.

Something I forgot to mention about the first run I described is that it was on 4S. I charged a 6S battery and was going to run it on the second run but never got the chance.

Once the cage mount broke, I wasn't too worried about it and kept going. I should bring some zip ties along the next time as I could have secured it with that, but the rear cage mount kept it in place for the most part.

The truck didn't really seem like it was going to wheelie on 4S. It was well behaved. Tracked straight and seemed stable at speed. I set it up with somewhere around 1 deg toe in front/rear. I'd rather have the rear at 0, but I wasn't going to change it as I didn't care about it that much.

I have a setup kit and at one point will set it up properly with that.

And the post mortem.

I printed that mount several months ago, and feel that I've improved my printing abilities since then, although I'm not sure I'd have been able to avoid this destruction. There does appear to be poor layer adhesion. I'm not sure what the infill was when I printed this part, guessing, I'd say 25%.

I've been kicking around some ideas for the cage mounts. Aside from the 3D printing I want to use, I want a quick removal process. A cage is great to have but they definitely make access more difficult. I'm thinking of a design where the cage will pivot/rotate in the rear, with a quick release in the front. Or maybe quick release front and rear and completely remove it. Not sure what I'll do yet.

For now, I'll just print the existing design in TPU filament to see how that holds up.

I'll also try 6S. If that's not insane enough, the motor/ESC I'm using can handle far more voltage than that truck normally uses.

A Graupner X-8E is on the way as well.

My MT410 was stored away in a Pelican case for roughly five years when I decided I should use it. I've moved to an area where there are more places to use it.

Got it out today after buying a Radiomaster MT12 to use with it. I have a Graupner X-8E but just never had any luck with getting it to bind with with the receiver. I started looking around online to see what sort of a presence Graupner has and I decided to get away from that brand as while some items can be found online, there doesn't seem to be a web site for Graupner any more.

There's a tennis court sized inline skate hockey court near where I lived. I took my MT410 there to run it around and get acclimated to it. It runs great! I was surprised at how well it handles. Only used it on 4S, and honestly that's probably plenty for what I'll be doing. If I went full throttle there was no way I was going to be able to stop it before it hit the barriers on the rink. This is a seriously fast truck. I thought I'd be dealing with traction rolls, but that wasn't the case.

So speaking of those barriers, I did hit them a few times (hard). Didn't notice any damage, so I kept going. I stopped the truck and found the ESC had broken off its mount.

I printed a mount for the MGM ESC back in '19 - and really wish I'd used something other than PLA. Sure, it's strong, but it's brittle.

This is how it looks when it's mounted.

The holes? Those used to be much smaller. There are screws that thread into the ESC that used to be located there.

I propped the ESC up so the screws are visible.

My 3D printer is out of commission for the time being, so I can't just print another one with a more appropriate filament.

I'll figure out something that will work.

Zip ties and some industrial 3M double sided tape are your friend.
