Strawb's Beetlejuice 2.2 Comp Crawler Thread

this is my project for the coming new year ..... i'll be documenting the build for all and anyone who might be interested to try out 2.2 competition crawling ....

i'll be updating the specs as i go along and i want to fabricate and muster most of the links and small ittybits as much as i can .....

as of now what i have so far is:

Berg V1 Front axles with 86 jeep style steering with vanquish high steer knuckles .... clocked 20*
Berg V1 Rear Axles with custom aluminum lock-outs super 300's 3rd gear
JR DS8711 servo with robitronics servo horn
Losi Comp Crawler Shocks
Beetlejuice V4 chassis
Vanquish Pro DH's
Vanquish SLW V3's
Nova's Double Deuce Foams
HB Sedonas


the bergs set-up for 12.5" in the setting jig

Nice strawb!

Enjoy the build!

thanks paul.

i think its quite obvious now how i love building these rigs .... there aint that much of a following here in the UAE but its really big in other countries ....

im just doing what i like and hopefully along the way i get to influence a few people to come up and crawl with us ....


your LCC still needs to see the daylight of the Al Ain mountains though .....

chassis is here ...

Y-town Beetlejuice V4 ....

a little more black & white flava









shocks and rear links mounted to the BERG axles on my setting JIG ..... still fabricating my front lowers and upper links ....

wow! . . . . nice educational build. . .

thanks chard ....

i first establish the 12.5" wheelbase as per comp crawler rules standards on my setting jig .....

i then install the shocks to see whethere i need to limit them internally or externally .... by doing this ... i can estimate and come up with how much articulation i want and adjust accordingly with the clearances the transmission and the bottom skid provide me .... (you have to lift and twist to see if there is no binding between shocks links and chassis)

"too much articulation isnt always good" ...... one can of coke is more than enough to achieve desired functionality ....

with the shocks in place .... then i decide how much front bias i want .... thus the reason why i have my rear lowerss installed and the front lowers are still under fabrication ....

hope this helps ....

as you can notice in this photo



i had to reinvert my shocks to normal as the shock cap was binding with the transmission box .... added spacers to the front top shock caps as well to achieve the desired angle and flexibility ...

the V4 as to compared to my V3 has the shock mounts waaaaaay inside the chassis ..... pros is that it will clear locks better .... cons is that you have to put spacers in both the shock caps and rod ends to get the clearances you need

here are some shock mounting pics from my V3 XR-10 ... as you can see ... the mounting is around 40-50mm wider than the new V4 chassis

wow! nice SCALER you have there straw...oooppsss....are you goin to join the Worlds?

thanks bandik .....

no i have no plans of joining anything ..... just enjoying myself with building these rigs ....

skills cant be bought from ebay!!!!

i just bought my skills from RCMart but unfortunately its discontinued now...i need to buy some hop-ups in order to gain more skills...

Any updates strawb?

saw it personally. sick looking rig
, and it's already a roller, with electronics on its way i think. . . . .

hey paul. . . . what's up?. . . may be one of these fridays you can come join us for some crawling in al-ain. . . . i usually go around 6 or 7am, so i reach there about 8:30 then start my trip back to dubai around 2, so i reach around 3:30. . . . the rocks there are unforgiving. . . . costed me 2 spurs already, but its definitely worth the trip. . ..

sorry for OT. . .. .

cheers

hey paul ..... thanks for the interest


i'll be updating real soon ..... just cut up some of my losi crawler shocks to fit in some CO cap mods! ...

i'll post up updated pics as soon as i get more progress


come down to al ain ..... i got me some really challenging gates for your LCC

cool will make a plan to come out towards the end of feb, but will be in touch before to make plans!

keen to see the berg progress!

just a few updates .....

first off .... i had binding issues with the stock Losi Crawler Shocks if they were inverted .... ended up installing them upright but honestly ... i wasnt happy with that set up .....

i wanted the shocks inverted ... why? ..... lower COG .... better response for compression when articulating .....

ended up doing a shock cap mod which gives me the option of using the revo shock ends ....






do take note that if you do this shock cap mod is that your losi shocks will extend to about 5" .... too long for my taste ... solution is to limit the shocks internally using a 25mm to 30mm spacer .... it does limit articulation play but it just works fine for me

FRONT




REAR





the clearances with the tranny is a lot better plus the play with revo shock ends with the cap mods are smooth as butter!

got me a few motors as well ..... they're not matched motors but both are high end brushed 35T hand wounds ....

i'll be running a REEDY 4 magnet up front and a HH 35T 3 magnet in the rear ....



my front axle motor will be a REEDY Flash Modified Quad Magnet 35T Brushed Motor

Nice crawler there stawb

thanks jon

motors mounted!

REEDY 35T up front



HH 35T in the rear ..... i also outboarded the shocks and the rear lowers ..... there were clearance issues with the shocks and the tranny .... now its all clear ....

i'm sure this will sidehill a lot better with the wider stance in the rear

Looking good strawb!

What's the reason for the different motors?

no particular reason paul ..... just got a good deal with some motors in RCC ....

lets schedule a crawl session this friday .... i believe chard and the others might come up to do some crawlin

Berg in roller form .... removed the external limiters cos i needed more travel in the shocks ...





front axle with 86jeep style steering




the mandatory flex shot




electronics on the way and we'll be ready to hit the rocks

just some weight comparisons

xr-10 (w/ electronics but without batts)



berg (w/out electronics and batts)

Strawbs Beetlejuice 2.2 Comp Crawlers

those rigs look sweet strawb!

which one do you prefer xr10 or berg?
