Roborg's (Cast) Bully Build

[roborg5000]

Ive had Jarod's HaVoc chassis sitting here for awhile now and just got these cast Bully's to test so figured now was a good time to try it out. at the same time I got a couple electronics upgrades as well (Futaba Steer servo, PunkRCDig. 2 great additions!

More pictures soon!

Video uploading now.

I wasnt to hip to the use of the cast material but, we will see how it plays out.

V4 axles had no breaks or bends.

I took some pretty good hits Tuesday night without issues.

My only complaint to this day is the loss of screws from the knuckles but, I had that problem with the originals as well.

Just keep adding the threadlock and eventually they will stay.

I did keep all my wheel weights in order to put the axles to the test.

I should have mentioned I only used 2 cross braces in the rear of the chassis by my 2nd run to gain more flex up front.

I also needed to space my torsion links out on the axle towards the rim more to clear the servo and gain more flex.

Not really. It worked okay, but it can be better. He needs to tweak that thing.

I was tweaking there with a few suggestions . Remember ?

I need to order that set of shorter shocks this week and go from there.

I have been using "shake proof" washers on one side of my knuckle bolts....and on the other I am running cap head bolts and aircraft safety wire....both seem to work well...I was gonna try permanent loc-tight..but now that i have the shake proof washers I think I'm good...







Looking good Rob!!! Nice vid too!


I'm dying to get my cast axles now!!! I got a new top secret chassis I'm gonna throw them under!!
keep up the great work.

Thanks Jarod.

I would say I just need some 80mm shocks and I will be good to go .

There is minimal threads in the axle for the knuckle to mount so the screw tends to creep out over time but, not all the time .

Invest in some M3 x 7mm button cap screws.

so Rob how do you like that new dig unit???

I need to check on these "shake proof" washers

Looking forward to the TSC too

I uh, Dig it .

Works wonders man.

To lose one mechanical switch is a great thing. Especially when ive had nothing but problems with all mini servos ive used for DIG!!!

Flawless operation. Switches never got hot either .

Indicator lights are cool when its 1am and you forget which direction front and rear dig is on your radio

Id suggest it . Best $50 I've spent in awhile !

Thanks for the reminder i need to take a trip there as well tomorrow !!!

I actually did forget until you said Fastenal

Red loctite seems to cure the loosening screws pretty well. I was having them come loose pretty much every run, then some red loctite seemed to fix the problem. They are tight, but not so tight that you can't get them back out. Just my .02.

bah bah bah. It not gunna werk becuz yu dnt hav ur pink nutz rooobbb

Cool vid.
That's one aweome rig.

Gents,
One thing I have noticed is that no one states having degreased the nuts and bolts before the locktite is applied, in model helicopter circles this is de riguer, I'm not trying to tell granny how to suck eggs but it has not been mentioned as far as I can see. Normally Blue locktite is used because once Red is apllied it sticks like Sh!t to a blanket and the devils own to get apart again. With blade revs up at 3K RPM blue works, this almost sounds like a mechanical tendency to unwind the nuts in which case wire locking may be a good compromise between ''tight nuts'' and put together for ever

There is no grease on these bolts

I just switched all mine out to cap head with a 3mm head with blue loctyte and keep one in my pocket. I started checking for loose screws between each course after losing a weight out of my vanquish wheels so its habit.

I'm not suggesting there is but lubricant from the manufactuing process can remain in threads, cleaning with alcohol just give the locktite its best chance.
