Need help with my G3-build

[JoFreak]

Thank's for the ebay link!
Have to think about it though, because it's blue
And I definately will get one of the GH 3905 servo savers.
I really don't like the "on servo"-servo savers.

By the way, forgott this:
Flextec answered, they recieved my bent upper a-arm last week and promised to send a new one on it's way in that same week
Great service, still sad though that they stopped production...

Thanks Neil, I shall give the GH a try this summer. I still don't trust the GPM =P

JoFreak, you could always strip off the blue anodizing. Glad to hear flextek took care of you also. Always such a relief when companies do the right thing!

[JoFreak]

Yeah I know that I could strip the anodizing from any part, but I don't like doing that kind of work
Regardles of that, guess what arrived today after just 48 days "on the road"?
Yeeeeees exactly, the GH steering from tower
I'm slightly puzzled though, not only didn't I have to pay any customs fees, but customs didn't even look at it

Better late than never

[JoFreak]

That's what I use to say.
But I really would like to know where it has been all that time.

As for the g3, I'm thinking about designing some specialized parts for the chassis.
Thinking about a diffrent upper rear plate, so that I can go lower with the motor and have a nice spot to put the MMM on.
I'm also planning a ne lower plate, that for one has a sealed underbody, to keep the dirt away. And furthermore for the lower plate: an integrated mounting plate to put the CD mount on, so I can get an even lower CoG. A possibility to mount some buggy or truggy dirt guards at the sides of the chassis. And the possibility to integrate custom battery trays, so that the batteries stop flying arround after a crash like they used to until now.
Maybe even a mutation of the shock towers and mounts as found with the gorilla suspension.
Aditional I'm thinking about a possibility to suport the rear of the motor against the chassis, but no real idea on that until now.
I'll see what my brain has in store for me when exams are over. Then I wil have the time to sit in front of my CAD program for hours and think of something... Apart from the times when I have to work to earn money to spend on RC parts

[JoFreak]

Little update, I got a new flextek a-arm this week!
But they didn't put a set of new bushings in it, so now I'm 1 bushing short, to mount the a-arm. Now I have to order a spare package of bushings from flextek and have to wait approximately another 2 weeks minimum

And now a short story of what happened to me today...
Doesn't really have to do with the g-maxx, but who cares:
I ordered a MMM/2650 set from tower in December, shipping per UPS.
I got that package about in the middle of December, paid 54,23€ taxes and so on.
Today I got a letter in the mail, with an invoice that there still was money to pay.

0,01€ (one euro cent) thats what it said

[suicideneil]

Good old Customs & excise eh?

They've had my MMM & pinions for a week now, still 'awaiting customs charging'... ¬_¬

Hows your build going? I was looking forward to a bash vid!

[JoFreak]

I tried a vid on page 6, didn't seem like too many of you were interested

Apart from that, the build is doing nicely.
I'm makin major changes at the moment, ditched the schulze 18.97kw and the bigmaxximum for a castle 1518 1Y and a mamba monster.
Also swapped the 2x2S hardcases against 2x3S turnigys.
Upgraded the servo and the steering, but I'm pretty shure I mentioned all of that somewhere in this thread...

As of this moment I wait for mike to answer my e-mail (disturbingly for sever about the custom battery trays I designed with CAD. Those should be a perfect fit to the G3 lower chassis plate and prevent the LiPos from flying around after crashes.
Up till now nothing happened, but up till now those were hardcase LiPos flying arround...

Furthermore I have to see when I find the time to bring the motor/CD mount to a friend of mine, to modify it so the slipperential (46T mod1) will fit into the mount and all together into the chassis.
And more importantly, modify it in a way that the motor will not collide with the heads of the screws that hold the top plate of the mount so I can use pinions in a size that won't make my truck hit warp 10 and travel through time

Could need some suggestions on how to support the rear end of the motor against the chassis though.

[suicideneil]

Hmm, to support the rear of the motor I'd go with a simple bar underneath the rear, with a concave curve to the upper surface- just like the revo motor mount conversion Mike sells. You could make the height adjustable with simple shims/ washers underneath it either end where it screws to the chassis, or something allong those lines.

[JoFreak]

That's what I had in mind.
Maybe get one of the Lehner motor clamps and use that together with some shims.
But it seems Lehner decided to improve the website and erase all the dimensions from their motors...
There is not much I hate more on the internet then unnecessarry site relaunches that make everything worse

So right now I have no idea what clamp would fit the castle 1518, if any.

[ZippyBasher]

Hey Jo, was wondering if you can tell me how the GH steering is working out for you... I was thinking of getting one... the Stock 3905 steering gets very sloppy quite quickly. even with the dual saver mod...

I want to try one of these out but dont want to blow my money on some crappy cast alu. that will get sloppy just as quick. Any advice is greatly appreciated. Thank you Sir.

[JoFreak]

I'm sorry. I didn't get a chance to drive it with the GH steering yet.
It definately feels high quality, not crappy at all and has less play in it than the traxxas stock steering.
As of now, I would buy it again and/but can't wait to try it out!

[JoFreak]

I'M BACK!
sort of...

It's update-time:
Since I never made a picture of the truck with body and wheels, here is one:

The body looks like that because I can't paint and because I drove it for about 5mins without tapeing it, so a lot of paint got blasted off by stones.

Without the body:


Now there is more space between the motor and the rear diff drive cup:

Also in this picture: my ingenious cable routing...

There's one of the 3 modifications that were necessary to get the castle motor and a mod1 46T spur in there. Mike was right (of course), countersunk holes wouldn't look right in that spot. But then it's form follows funktion and not the other way round:

Other modifications were: 3/10th mm deep pocket in the mountingplate to clear the 46T spur. And 3/10th mm removed by milling where the mountingplate touches the x-braces, so the diff sits higher and the spur clears the x-braces.

New servo, Hitec 5955TG held in place with full force servo clamps:


And that's about it...


Hope you guys like it, looking forward to your comments and suggestions on what could be done better

[Kcaz25]

I love it, now as I did then! You build a truck quite well sir. Do you now wish that you would have painted the inside of the body? lol
