project 3905 e maxx

[redshift]

I was gonna get back to this thread earlier... sorry!

Ok yeah, same deal with the oil treatment, very small amounts. I just recommend that because it's available anywhere, and cheap.

You are quite correct about the bad mesh on the Traxxas ring/pinion. And this has still not been addressed. Same goes for the spiders. It's a shame they refuse to make improvements where they KNOW they need to. But then they don't make their money from RTR stuff do they... As far as shimming the rear, I have, but it seems to make no difference. Maybe amounts to minutes lol. So I just consider those expendable. I've considered going with an all metal trans, but it hasn't been an issue. I know about letting off when you shift.... just not that one time I don't really do much crawling, but first is just perfect for some things (like when you blow 2nd). As for the Mutation, that was started before I really knew about brushless at all. I didn't anticipate what it would become, past brushed. And the timing with brushless worked great for me as I was able to do a reliable setup and not go thru all the experimentation with different power systems. I say reliable electrically

I've considered going with the 1/8 diffs, but there are a few things that would pretty much necessitate a full redesign, so it may or may not happen.
But who else can say they've gotten 4 years of fun from the same RC?

And yeah BattleBots/Robot Wars did inspire me somewhat, and a self-righting device would be the cats ass!

There is a lot I'd like to do with it, but if I did I'm afraid there wouldn't be enough 3906 left to call it such. The 'train was adequate for brushed power (barely) with some CVDs, and I did go thru a few sets of plastic idlers, but really I had no idea what MILD brushless power had in store for it.

Your machine work looks very good, and I am extra impressed you're using conventional machines- I have a CNC allergy. They make unbelievable stuff, and I work around them, but I am oldschool. And there are still lots of things that cannot be made by CNC. I let the pros do the programming, I'll have the part made before they have their program imported :)

I have a diverse background, but no experience in gearcutting. Nice to have a few who are experts on such things, besides the Monster himself of course!

Looks like a good playground there too

hi all/redshift...will look into a splash fed box when i get my alloy casing , sounds like the best idea..
so what wheel shafts do you use on your maxx? mip's

i can see why you dont want to change over to bigger diffs, shame tho as it will turn out much better than before.. i found this with my work.. if you get it wrong you will get it right next time . i can say ive had several years of good running with my e maxx and its just getting better now brushless is available.

thanks for compliments on the work, when i first machined a cog the calculations looked confusing and i was not really sure what i was doing was right, like any job i suppose, now ive cut a few its easy. bearing in mind its just a copy job not a gear train from scratch. try it if you have the machinery, get the o.d right then its all down to cutting depth and correct indexing.

the beach is great.. they get a bullbozer down there and build up the sand to keep the water off the road when the wind gets strong in the winter. theres a quater mile streach of it see ya all...
