Dr.Frank's XR take II CK Fly V1
 

Hello,

after running my Berg for awhile now and some personal circumstances i sold it :cry:

But RC Crawling is like a virus, once you get infected...

...so i will build me a new car for 2012. I'm short of time and so i'll give the XR a second chance.
It has a lot of advantages and meanwhile there are some realy good aftermarket parts.

Still waiting for some parts but i'm collecting some for now and can make a start:

The box contains parts for two front axles and a bit more. Her's a short list of what i get so far:

VP Chubs
VP Wraith knuckles
VP Rear lock outs
VP Upper link mounts
VP Upper axle housing
VP Servo armor
RC4WD Gears
RC4WD Housings and motor plates
Axial Front CVD's
Axial Lower axle housings
Axial SCX10 shocks
Losi Springs
Dr.Frank XR/Wraith steering arms
Dr.Frank Ti steering rod
Dr.Frank Ti rear straight axles
Dr.Frank Mini-T shock retainer and SCX shock cups
...more will follow...

I'll run 2 front axles and the "only" thing i do by my own were the Ti straights for the rear front:

I turned the rear lock outs a bit for more clearance and drilled new mounting holes:

I clocked the chubs one klich more backwards to get more caster. Therefore the Wraith knuckles are a perfect fit:

The servoe position will be changed the "Egressor" way, but next year:

...some goodies are still on the way to good old Germany and i've to wait til next year to go on with building :roll:

What chassis should i take, the Rockshow SS or "Q's" ahh "J's" special agent equipment:

Happy new year to everyone :D

I may be biased considering i don't like bodyless and i just got a S-A, but, i would go with the S-A. I run a front axle in the rear and the chassis works great set up this way. The only differences from krawlfreaks set up is the external limiters on the rear shock have to go on the inside and the rear lower links have to be made a little longer.

Nice looking build DR Frank!!!! Looks like all the right ingredients for a recipe of WHOOP ASS"thumbsup" Can you explain to me the benefits of rotating the C Hubs up more than stock allows, I have seen this done before but havnt had time to follow through with the reasoning.

Re: Dr.Frank's XR Take II special agented
 

Your sig says your a Chaotic team driver, surprised your not running their chassis. I would go with the SECRET AGENT for sure, it's the latest in innovation. "thumbsup"

Re: Dr.Frank's XR Take II special agented
 

Can't wait Dr. Frank, good parts list I'm sure it will be great.

I have to say I used to dislike the bodiless until I built one and I'll never go back to a body on a crawler ever again. They even look more realistic. "thumbsup"

Re: Dr.Frank's XR Take II special agented
 

Are those Dr. frank titanium rear straight axles for the front housing something thats available?? I would like to do a similar build on my rear axle!! Those axles shafts are the only thing setting me back at this point that i know of. Let me know if im overlooking something. If yours arent available do know of any that are? That seems to be that best route to take before dropping some cheddar on VP upper axle halves"thumbsup"

...you can't always get what you want...

...please don't worry when you see the build progress pics, the body is just for hidding the chassis :mrgreen:

...time will tell ;-)

During the past weeks it made some progress:

...as you can see, carbon, but no agent (BTW agent is at 49g, this one is at 52g). Guess which chassis it is ;-)

I made several tries to run all of the electronics on the front axle, but i didn't like it. So i did a quite clean "standard" wiring job with ESC, RX and BEC on the skid. To get rid of battery scraping, i put it behind the motor on a Rowdy Racing mount.
The actual setup is very close to my Berg, but has a bit more max ground clerance (100mm front of the skid and 110mm under the rear). Ride high is on 85mm in the front and 95mm in the back. Weight is at 2055g RTR (without wheel or knuckle weights) and it wil get some extra weights for a better balance.

Is that one big capacitor instead of two stock?

Re: Dr.Frank's XR Take II highflyed
 

Awesome Doc. "thumbsup"

Re: Dr.Frank's XR Take II highflyed
 

Looks amazing Dr. , What hubs are you running with your SLW's?"thumbsup"

Re: Dr.Frank's XR Take II highflyed
 

Sweet! Love the body. "thumbsup"

Re: Dr.Frank's XR Take II highflyed
 

Jep, 680µF/25V

Thanks Rick.

350 front => 280mm => 11.02" , 600 rear => 275mm => 10.83"

Thanks, but i don't know how long it'll stay on...

Greetings Frank

Re: Dr.Frank's XR Take II special agented
 

That is an inch more max clearance than I have under the skid :shock:. That would be like 4.25" at the front of the skid :shock::shock:.

Looks great though. How does it sidehill?

Re: Dr.Frank's XR Take II highflyed
 

Well since your asking for a guess on the chassis I will go ahead and guess that's highfly's carbon fiber work?? Highfly seems to be the German CF master... ;-)


Looks super clean frank....like all your builds."thumbsup"

Re: Dr.Frank's XR Take II highflyed
 

You've got a nice touch the rig looks great. "thumbsup"

Re: Dr.Frank's XR Take II highflyed
 

Thanks Mark and you've got a Bingo ;-)

Made some Wraight knuckle weights, 110g (3,88oz) each, so it's one 2217g (4lbs14oz) RTR now :mrgreen:

Greetings Frank

Re: Dr.Frank's XR Take II highflyed
 

Very nice work...super clean...really want to see it in action 8)

Re: Dr.Frank's XR Take II highflyed
 

Looks very very nice.

Re: Dr.Frank's XR Take II highflyed
 

The weights look phenominal. I'm especially digging the taper on the back side"thumbsup"

Now you just need to make some thick brass inner SLW lock rings with a coutnerbore for the hardware8)

Nad Why are you keeping the chassis under wraps? I wanna see what it looks like.
