"Twin 2" The Research & Development rig

[tomster]

After the fun i had building & running my "Crawl-Hammer", i kept my eyes open for spares and used ones.
Two weeks ago i came across a well beaten TH without electronics except the 15t motor and with a broken front dogbone pin and broken wheel hex pin.

I will use this rig to try a few things, mostly electronics, tires and TH parts.

After a few hours of disassembling, cleaning and fixing, the rig is running with some spare electronics i had laying around.
I installed a Hitec waterproof steering servo, a Turnigy 6V-3A BEC and a Hobbyking X-car ESC along with the stock motor with a 20t gear to improve crawling abilities.
The rig came with HR aluminium hexes and a front locker. I went back to the open front diff with some add of a sticky rubber based material i got from a toy (silly putty`sh). The previous owner installed a Losi Night Crawler driveshaft for the rear end, i didn't liked it and installed a Traxxas driveshaft mostly for the scale-look. to protect the shaft i made new longer upper links out of 4mm solid Carbon-fiber and Traxxas heims.
I also did inspect the transmission and it was in excellent conditions, no wear at all, so i lubrificated it an it runs butter-smooooth...!!!

Which traxxas driveshaft did you use?
Thanks!

[tomster]

Its the traxxas #1951 half shaft kit together with the Traxxas #4628X hardened steel yokes.
I used two female shafts and one male shaft wich i sleeved internaly with a 4mm Carbon fiber rod, to get a longer and stouter driveshaft.
Love the scale look of those on the Twin!
I already used these shafts on several AX-10 builds and are very happy with the weight/strength ratio they offer!

Cool! Thanks! Do you have a close up pic of the complete shaft? Good idea!!

Hi! I will make a pic next time it is open!
In the meantime i installed the Vaterra HD outdrives for the front diff:




They seem really beefy and well made!
To get all the suspension up-travel i had to grind the A-arms a bit because of the bigger OD .



While i had the front-diff open i filled it with 1.000.000 fluid from Hobbyking (trackstar),
but after a few tests on the rocks and a gravel road i will go back to the locker!
it is way too hard in the fast stuff and opens to early on the rocks.
For the upcoming European G6 in Austria i will install a 35t motor instead of the stock 15t, it seemed to fast for my style of driving...

Installed a 35t RC4WD can and love it!
I also got some new tires and wheels : Iroc RC4WD on Axial Beadlock and my own "Trail ready" rings:
