Upgrading my 3906

[SnoopMaxx]

I am saving for a MMM
but until then I use brushed motors

New photos later

[SnoopMaxx]

I made a 775 motor mount that centres the motor and I got Mod1 15-16-17T pinions and 49-52-54T spur gears
And I ordered new harder shock springs

That's cool! Looks like a puller truck....keep up the good work!

[JERRY2KONE]

That is one strange looking Maxx. So how are you making your own driveshafts? And what body is that? I have never seen an R?C 1/10 scale that long before.

[SnoopMaxx]

I don´t think it´s 10th scale more like 1/8 scale

I get my inspiration from full size Icelandic Formula Off-Road and Finish R/C Foff Racing

Take a look at these photos and videos

Son of a biznatch, thats what I've wanted to build for my whole R/C life- those Icelandic trucks are awesome, always loved the mentalist attitude and driving.

As it is, I'd like to make a cage like that for my Gmaxx chassis, prefer it to a shell really.

Assume work SnoopMaxx, do you have any pics of the new transmission/motor mount, its obscured in those pics?

[SnoopMaxx]

Neil Tha´t not my Foff
It´s just to illustrate where I get my inspiration from

Here is the new motor mount I made

Sorry you will have to wait a little longer

All will be reviled soon

The motor mount in Nightfall


Motor mount in Red Devil


From what I can see they use RCM mounts

And my new Mount for the 775 motor


extended driveshaft made from a piece of 6mm Steel

I just figured out what to do with whats left of a 3mm sheet of 6061 I have left lying around...

Clever motor mounts- I've seen stock 3906 motor mounts doubled up to flip the motor around before, but thats only about the second I've seen that centers the motor in the chassis.

I wonder if FoFF cold take off in the states much like crawling did, would make for a much more exciting offroad scene (crawling and racing combined)...

[SnoopMaxx]

The motor mount are designed after the 4:1 reduction gears I made for my Clod Buster
and my Tamiya 3 Speed in 1987-88ish
It´s just a little bigger

I know that there are many 2.2 Foff builds on RCCrawler
(some of them are based on my 2.2 rig)

It would be cool to see more Foff builds in The UK and US

Update on the Tranny modification to mount 3905 steel idler gears in the 3906 tranny
2nd gear Idler is grinded down to 11mm


1st gear idler is 13mm wide, total with on bracket is 38.4mm


Idler shaft bracket is filed down to 17mm so the idler gears can spin freely

[JERRY2KONE]

On one of mine I just took the dremel and removed a few thousanths of an inch off the case where the idler shaft bearing sits. Everything rolls like a charm. I have the RC4WD aluminum tranny 1st & 2nd gears in it as well.
